This system works??

These species can live in the same water, but in the separate tanks??

And this tank dimensions(0.8m X 0.3m X 0.3m) are appropriate to reproduction for this species??


Please, I need suggestions!!!

My concern would be cross contamination of any possible disease outbreak by sharing same filter system and water. (But then maybe I don't understand your setup?) Looks clever though.

Also, the cristatus need cooler water than the pleuredeles prefer - you could only have one temperature with shared water.

Hum... Thanks!!
Temperature and disease problems are risks that everybody here are susceptible...

In the ornamental fish trade, this setup is very common, for possibility the control os parameters...

exists toxin problems??

(sorry for the english!!)

You asked if the tank dimensions are appropriate... it depends on the number and age of the larvae. In my estimation, that size would be OK for a maximum of 15 Triturus cristatus or 10 Pleurodeles waltl (at the size approaching metamorphosis).

One other problem: when metamorphosis approaches, they need a very secure lid.

I would not expect toxin problems, but I do not know for sure.

Would you use some cleaning (siphon) in addition to the filtration? Your filter system does not remove garbage from the bottom of the tank.

Good luck with the project.

Hi Jennifer, thanks...

This setup is for the adults only... The supposed eggs are remove to other tank for eclosion, without circulation (with light air pump)...

These two species can copulate in this setup and in this dimensions tank??? I don´t have experience in these species, anybody have here in Brazil!!

sorry for the English..

For the adults, I would recommend a little deeper water. In your diagram, the tank is 0.3 m tall (about 12 inches), but only half full. The overall size is enough for the adults (one pair) to mate and lay eggs.

Both tanks will need secure lids. And will there be a screen to prevent the animals from going from the upper tank to the lower tank? They can climb.

Is the brown square some kind of island? T. cristatus are mostly terrestrial in summer. They need a large island, or else they need to be kept in a completely different (terrestrial) tank during the summer months. In contrast, P. waltl do not need any island.

I would say that this could work... but two separate tank systems may be easier to build and reduce the possibility of cross-contamination (both toxins and diseases).

Jennifer, thanks again!!

Lids are necessary... I'm provide this! The island portion (symbolic brown square) have been installed according to specie requirements... (T. cristatus with 1/3 of land and P. waltl with a just little portion)...

I'm revise the dimensions tank... According to the support (rack), the aquarium can to reach 0.9m X 0.3m X 0.4 (height)... Can I keep 4 adult specimens in each tank for reproduction? Who sex ratio?

Sorry for the poor English and all questions!! I'm a newbie...
