Species Mixing Disasters

 

Mixing any two species of animal in captivity requires careful consideration. We are all accustomed to the idea of "community tanks" for fish. Naturally, many people assume that the same can be done with amphibians. Not so. Salamanders and frogs are carnivorous predators. They are also slow-moving and easily injured by other animals. Thus the potential for disaster is rather high.

For some general information about mixing species, we recommend:

In this article, we have attempted to collect photos and examples to illustrate species mixing problems. We hope that these examples will prevent people from repeating similar mixes.

 

newt eating frog
This Pachytriton makes a snack of an African dwarf frog at a pet shop.
interspecies newt amplexus
The mating rituals of one species, such as this Notophthalmus viridescens
can be dangerous to animals of other species that are not adapted to that activity.
newt eating axolotl
Given a brief opportunity, this Pleurodeles waltl ate a young axolotl. See Incident #51 below.
newt impaled by catfish
This paddletail newt was housed with a small catfish. The spine of the catfish is protruding from the newt's chin. The incident is described in a forum thread. A similar incident involving a firebellied newt is described below in Incident #28.
axolotl with snail in mouth
This axolotl tried to eat a snail, but was unable to either swallow it or spit it out. The snail had to be removed manually with a tweezers (by turning it around). The axolotl had a swollen mouth for some days but eventually started eating and returned to normal.
newt eating newt
Juvenile Tylototriton verrucosus eating a dead tankmate. Although this is not an example of a mixed-species problem, it shows just how large of a prey item a newt is able to devour.
axolotl eating cory
This axolotl attempted to eat a large cory catfish. The cory died and the axolotl suffered injuries due to the spines puncturing its head. Details below in Incident #59.
axolotl eating catfish
This axolotl attempted to eat a catfish. The fish died and the axolotl suffered injuries. Details below in Incident #72.
axolotl eating guppy
A juvenile axolotl eating a guppy.
axolotl eating goldfish
An adult axolotl eating a goldfish.
tiger salamander injured by pufferfish
A larval tiger salamander injured by a pufferfish. See Incident #77.

To everyone who has debated wether keeping FBNS and FBTS together, i would like to share my little story with you. I had my FBN and FBT together for a while. I was sure that keeping them together would be fine. Then one day while feeding them, the toad attacked the poor newt and took off a toe or two. It was then i decided to seperate them. Only good things have come from this. My newt seems much more active and less stressed. He eats more and appears more healthy overall. Same with the toad, who never spent time in the water... now he does! Keeping these species together only causes stress to both creatures. Thanks so everyone in this forum who convinced me to seperate them, it was a good choice.

Hi,
I'm pretty new at the newt thing. I originally had 2 firebelly newts. One died of what appeared to be a white infection on his foot, which eventually fell off, then he died. While his foot was injured he didn't eat either. Now, a few months later, I've got one newt and added a little albino frog in my tank - and my newt has a foot injury/disease. He isn't eating. What is going on here?

Twice, I tried to keep African dwarf frogs in with my tank with 4 eastern newts. Both times the frogs died after only a few weeks or months. The frogs were often swimming frantically and became skinny, so I think they were just stressed by being with the newts. Also, the frogs may not have gotten enough to eat because I was feeding the newts only twice per week.

November 08, 2001 at 13:16:43:

my very first salamander ever was a mandarin. i had no idea how to care for it, so i put it in my red-eyed tree frog tank. needless to say, the 80F degree temps alone took their tole on the mandarin. not only that, but one of the red-eyes died in the same week i put the salamander in, probably because of stress and/or foreign pathogens. so, i quarantined the mandarin and did my research on how to care for her and what went wrong. she stopped eating and began to develop white sores on her head and lower back, which i treated with kanacyn and neosporin. i think that the only reason she lived is because i got her out of there just in time. i learned a hard lesson about researching species before purchasing them

... you got problems. First of all, look at the source...Petco? They mix species to cut down on space or are just following some stupid retail schematic. I was actually dumb enough to buy a newt from Petco and drop it in my tank w/ 4 FBT's. Two days later the thing was walking around w/ only 3 legs. So I took it back and haven't bought any live animals from them since. Besides, I believe newts don't really like anything above 72 degrees.

"Newts with ADF"
Received by e-mail

Hello!
I recently purchased 3 tiny fire belly newts from a local pet store. I thought to make a good home for them. According to the people at the pet store I could house the little newts with African dwarf frogs. In fact, they had both in the same tank at the pet store. I brought home a few of the frogs and newts and find out the next day that a frog was attacking the newts. One died, another has lost toes and a small hand and looks to be loosing another hand, and the last one lost a few toes and has developed mouth rot. I've had them for only 3 days. It has been horrendous.
Due to kind people such as yourself I've been able to do much research on my new, yet very ill newts. Thank you for sharing your knowledge.

"Fire belly toads with fire belly newts"
16 May, 2002 - 05:00:

Can this be possible? I added the two newts to the tank with the toads. All the animals are the same length (not including the newts tales). After a few hours they all seemed happy together climbing and jumping around very close to each other.

About 3 hours after I added them to the tank I feed the toads and newts pinheads and worms. One newt ate a worm and the other was hanging around on the wall so he missed out. The one decides to come off the wall. This is when the bad happened. One of the toads struck and got the newt in it's mouth head first. It went do to the newts front legs. I took the newt by the rear section and pulled him out of the toads mouth. The newt seems ok and swam to the shore to hide in a cave. He hasn't come out and the toads don't get close.

Did it strike because it looked similar to the worms it ate before or should I seperate them immediatly?

Thanks!

I had a Pleurodele newt that was the "runt" of the batch and was the last to morph. He was small and I literally had no place for him; all the other siblings were 2-3 times larger. I thought I would put him into my Red spotted newt setup. Well planted setup and the newts were the same size as the spanish ribbed newt (pleurodele). I also thought, hey this species is very "docile" and "mellow". To my surprise, the Red spotted newts ganged up on the pleurodele immediately and chase him around the tank! I had to keep this little guy in a generic setup until he put on weight.

I knew Ambystoma larva not only eat other conspecifics larva, but also their own kind...I thought because they were the same size and the setup was large enough, it would be ok. Wrong...very dumb mistake. The axolotl larva swallowed the maculatum larva whole! He found a home alright...not what I had in mind. I felt very bad about this.

Right now i am having a big problem where my newts and a salamander are being aggressive to the others. I had a Jap. Fire Belly newt, Paddle tail newt and a tiger salamander. With these together i noticed that the fire belly ended up losing 2 legs(at different times). And the tiger salamander had lost a little tip of his tail (about 1cm lost). I had heard that paddle tails were aggressive so i seperated him. Every thing seem to be going good until i got an California newt today and the tiger salamander was trying to bite off his hind leg. Luckly i saw it and save the newt.
Right now i have the tiger and the paddle seperated from the other 2. I am wondering which one is the aggressive one? (or is it both?)
Any info would be helpful!

Ps-The main tank is 15 gallons (long) and the tiger is about 8 inches. The others are about 5-6 inches long.

I noticed that the cfb seems very territorial at times--biting the newts, yet other times they all lay together. Why does this happen?

Also, I noticed that the two new newts werent eating. One of them was very small; he was most commonly attacked by the cfb. I've had the two new ones now for approx two wks. Yesterday, the small one died. I thought it was bc he had not eaten. Do you think this is the case?

And finally, I noticed a small white sore on the cfb tail. I originally thought it was a possible bite, but with further examination I believe it could be an infection. Today I noticed that the remaining eastern newt has a similar sore on his tail yet much more severe.

I lost a dear little 10 year old Fire Belly Newt (Wayne) when I didn't know of the spines and added a small algae eater to the aquarium. Wayne died 2 days later with the fish impaling his throat.

Then one day I noticed the betta take a peck at one of the newts. I didn't think much about it, but the next day the betta was pecking viciously at the head/eyes of the newt again and the newt was swimming to get away. I removed the newt, which, over the next few days developed a bruise-colored head, but did survive. Then the betta started picking on another of the newts, so I immediately removed the betta.

November 08, 2001 at 16:45:27:

I tried to cut feeding expenses and started using feeder fish (rosies) for my Spanish Ribbed newts. I lost 3-4 newts from bloat or disease. The only source that I could trace this to is the feeder fish. I also tried to add corey cats (fish) to eat the left over waste in my pleurodele tank. My reasoning was to keep a well balance tank and decrease need for water changes (these newts are big eater and poopers). By day 2, I noticed one of my breeding females had eaten one of the fish...but it got stuck in her mouth. Most fish have sharp fins. The newt suffered mouth lacerations and developed a nasty infection and died several weeks later, despite antibiotic therapy.
I lost a beautiful paddle tail newt by feeding them diet of rosies (fish). He died from infection like the spanish ribbed newt. He linguered on for 2 months.

My other newt is a CHinese fire-belly. He was doing well, but recently I noticed that some of his tail had been bitten. So I put some healing liquid in, and feed his favortie food, bloodworms. After a couple of days, I got worried. Then I looked closer at his tail, and relized the white that was sticking out wasn't flesh, it was bone!!!

They are both fire bellies, but I thikn the new newt is Japanese. I bought a few more gentle fish with the new newt. But, the bite was there before, so I will list the fish I had when I first noticed the bite.

Fire Gourami
Neon Tetras
Corydara
Black Phantom Tetra

I suspect it was the gourami, but I cannot be sure. Since the tail was bitten, the newt has been curling his tail upwards. What should I do? Please help!!!

As long as it was not a danger to the newts, I thought all would go fine..The crab was twice the size of the newts..too big to get eaten..the pleco had spines on its back to keep it out of the mouth of a newts...WRONG

MAN WAS I WRONG!!!! I the crab lasted a week, came in one morning & the newts were having a feeding frenzy. the big female was really fat with crab.. The pleco lasted only 3 days..I saw a strange tail in the mouth of the male. Guess the spines were not a problem.. I have also tried big apple snails...just to have them pulled out of the shell. Ghost shrimp...gone in a day..AND I WILL NOT EVEN START WITH TINY LITTLE FROGS...tiny newt food.

I have learned NEVER mix animals with newts. I am just glad that the newts were never hurt in all of this..

Hi, I recently add some hatchet fish to my fire belly newt tank. During the day there were no signs of problems, but the next morning all the plants were shredded along with the newts! I never realized these fish were so aggressive. Its too bad my newts had to pay the price for my ignorance. I thought I'd pass this info along and see if anyone else has had a similar experience.

36. Axolotl + Apple snail
"Snails--Advice?"
March 14, 2004 - 03:24:

I recently acquired 4 axolotls. Ranging from 1 1/2" to 2 1/2". I also raise apple snails. Apple snails have an operculum or door to their shell that they retract inside when they pull in their foot. The operculum is made of the same material as the shell and therfore hard with sharp edges.

After settling the axolotls into their tank with a few apple snails, I left them alone for about 30 minutes, and when I returned, the largest axolotl (also my only leucistic) had its head inside one of the snails. This particular snail was around 3" in diameter. What probably happened was that when the axolotl investigated, the snail tried to close up into its shell.

Well I pulled the shell open enough to get the axolotl out and the operculum had cut its throat, of course killing my axolotl. If I had left it in the tank the snail probably would have eaten what it could and the other snails would have joined in. If you have a weak or injured fish, newt, etc. or something that simply cannot get away from a snail it could very well be eaten.

Please also add, that while snails may be slow, they are still very interesting and amazing creatures to keep. Also, that while larger apple snails pose a danger to soft bodied creatures (and this only because of the previously mentioned self-preservation ability) their are many other species of snail that do not have a "door". Therefore being safe for any, but slow, sick, or injured creatures.

More recently I have fed Danios purchased from someone who cultures them. The newts ate the smaller ones, but the larger ones just ended up stressing the newts... so I removed them.

I agree with Kaysie... fish aren't a very good idea in general.

I "rescued" a White's treefrog, a pair of green treefrogs, a barking treefrog and a firebelly toad. As if this weren't bad enough, I put them in another 29 gallon tank with a firebelly newt. I still have the newt and the FBT (in separate tanks) but all of the treefrogs perished.
The same store had another tank with sliders, anoles, garters and rough green snakes.
I thought they had a clue but they were just trying to move their product. My new petstore generally keeps single species only tanks :)

"The dangers of Otocinclus"
30 December, 2005 - 16:02:

Something very terrible happened.

This morning I looked into my tank and saw Grimace go up for three or four breaths of air right after another, then sink to the bottom and flop on his side. His head was very swollen like he had something stuck inside of it or his throat.

I removed him quickly and put him in a bucket with fresh declorinated water. I know normally one should not hold an axolotl, but I had to hold him to look into his mouth, and sure enough he had tried to eat one of my Otocinclus. Its sharp little fins has become lodged in his throat, so that he could neither swallow or spit the fish back out. He was suffocating. I successfully removed the fish, which took about two minutes with a smooth metal stick and now Grimace is in the fridge with a little salt and is doing much better. If I had not seen this happen this morning, I probably would not have noticed because I have been so busy, and he would have died.

The little fish survived, and I am glad for that. I am not sure how Grimace was able to catch it, but he did, and is suffering for it now.

For anyone wanting to get these fish... Don't. I finally see why. They are small, they stay small, and can get stuck inside of the axolotls mouth and cause death.

[Question about adding a crab as a tankmate for a firebellied newt].... This particular combo is a bad idea - I've tried it. I had to seperate the two within 15 minutes. The crab didnt move for the first five minutes or so, until the newt got close, at which point it lunged for it and settled down again. Stupidly, I didnt split them up then but kept watching. The newt climbed out and retreated to his burrow (a partialy buried cork bark curl against the side of the tank, siliconed to the back wall), the crab followed shortly after. By the time I'd literaly ripped the tank apart to get to them, the crab had the newt in both claws, the rear third of its tail was completly mangled and one of its back legs missing. Despite my best efforts, the newt died 3 days later. I later moved the crab to a community aquarium, I'd lowered the water level so there was some wood it could climb onto. I'm not sure how it managed it but two days later it had chopped a male betta's fins to pieces, that died as well. It was a viscious little git.
