Is this info correct

i have just visited this website
http://www.pollywog.co.uk/qanda.html
this site is telling people that they need a heat mat and uv light to keep tiger salamanders.
I was advised to use neither of these things when i bought mine. (i have had him for a year now and he is thriving in his environment).
please clear up this matter for me and possibly advise the site on their info (if incorrect).

In the wild, tigers spend most of their lives underground, coming out only at night and to breed. How could they require UV with that kind of lifestyle? Underground burrows stay cool year-round (think about what it's like in a cave). So how could they need a heat mat? If your house goes below freezing in winter, then sure, they need a heater.

See:

I have already answered this in person to Nathan but wanted to answer on hear as well.
The care sheets are to be used only as a guide to the care of a species and I always recommend that a person reads as much as possible into the species they are interested in, not only to go by my care sheets.
The temperatures given in the Tiger care sheet where advised by a friend who kept them for many years and cross referenced with a number of books, however since keeping Ambystoma maculatum and Ambystoma opacum myself I would agree with you that the range I give may appear a little high but still should do no harm. If you look at my recently added sheets for the Spotted Salamander and Marbled Salamander I do not recommend the use of additional heating if kept in a warm indoor location. I have altered the Tiger Salamander sheet to show this. As for UV light, the importance of UV light to amphibians is a discussion I have had many times. I have discussed this a number of times with many scientists, traders, breeders and keepers from across the world and we never have come to a conclusion as to whether it was needed or to be recommended or not. It is my preferance to provide a UV light and I do so for all my animals and therefore I recommend it.

Can you supply the temperature references for the recommended husbandry temperatures of the tiger salamanders? I would be interested in seeing how the recommended values in these books goes with some of the recorded thermal maxima in the scientific journals.

With the use of UV with amphibians are you referring to the use of UVB for vitamin D3 sythesis or to the use of UVA for behavioral stimulation?
This is a different subject when referred to anurans as opposed to caecilians or caudates.
Exposure to UVB is known to cause Triterus cristatus carnefex to develope epidermal hyperplasia, erosions, and ulcerations. Increased shedding was also recorded in newts exposed to UVB. Additonally UVB exposure to prevent "metabolic bone disease" has long been suspected in causing keratitus in amphibians. (Both of these can be referenced from Amphibian Medicine and Captive Husbandry, 2001, Krieger Press). I would be very hesitant in providing UV lighting to any caudate.

PS: I am unaware of any reason to supply additional heat to marble or spotted salamanders as long as the temperature does not go below 40F (4.44 C) as these salamanders are well documented to be active and to feed at these temperatures much less be kept in a warm room.

Hi Andrew,
I notice that on your website mentioned on your post above, that you advertise animals "available to order", taken from an importers trade list. (Last update 29/05/04)
I find this somewhat misleading, as he clearly differentiates from WC and CB animals, as indeed you do, but not necessarily the same species!
 
I can not quote the books given temperatures off the top of my head but will happily look them up for you when I get time at the weekend. I am not aware of the problems you state with using UVB light for Caudates but will check up on it, I have been after a copy of the book you mention but have never managed to lay my hands on one.
I do not recommend additional heating for the marbled or spotted salamanders I recomend them to be kept indoors, I am sorry if this is not clear, I must admit I am not the best at explaning things, but I do try. As I say, the care sheets are done to the best of my knowledge and obviously at times I get the odd thing wrong or word it incorrectly, I'm sorry. Thank you all for your input I will be sure to look at the care sheets and change accordingly, If you would all be so kind as to check my other care sheets for mistakes I would be more than gratefull for any comments as the last thing I want to do is missinform people.
The livestock list on my site is correct to my suppliers list, I change the "common" name on a few species occasionaly like this week my supplier has T.montandoni as Montadons Newts, I changed the name to Carpathian Newts as I think it is easier for a potential customer to find information on them if they look for the Carpathian rather than for Montadons Newt, it is the same animal, just another name for that animal, I do not mean it to be missleading.
Many thanks, for all your comments,

"Herptoculture" in recent years has improved immeasurably, with many reptiles being captive bred in all shapes and colours. Wild caught is very occasionally found on dealers lists of the commoner species, as healthy "better do'ers" are produced in enough numbers to satisfy the hobbyist/pet market.
Likewise, Dendrobatids, Mantellas, and other frog species, through necessity, are now bred very successfully for captive/conservation purposes.
"Caudateculture" I feel is still in it's infancy, and many common species are still imported in large numbers, (mainly from Asia and the former Soviet Union), often languishing in squalid, overcrowded conditions, in uninformed pet shops, and dying an early death.
Care sheets, with the correct information, is admirable, and these should be encouraged.
I feel Forums such as this, educate anyone who is mindful, to keep and breed these wonderful animals, in the correct conditions that they require. The many knowledgeable people who contribute to this site should be admired.
I remember when I saw my first fire salamander, some forty five years ago, in the back of a Florist's shop.... he used to collect moss and ferns in France for the shop.
Then there were european pond tortoises (Emys orbicularis) and tree frogs, (Hyla arboria) in the shop. I kept the frogs in tall glass sweet jars, and fed them on "bluebottles", hatched from maggots, collected in a bucket full of sawdust, under a piece of rotting meat....my mother was not amused. When Autumn came, and the food source ran out, I released the frogs around the pond in my parents back garden. The colony survived for twenty five years, when my parents sold the house, now directly under the main flightpath of Heathrow Airport. The new occupants filled the pond with gravel, to create a low maintenance garden. There are still chirps at night though, from the midwife toads,. (Alytes obstetricans)
In the following years I journeyed Europe extensively with my parents, and collected many species/subspecies of Salamandra, the offspring of which I still possess.
Both releasing non-indigenous animals and collecting salamanders, are now of coarse illegal.
Sorry, I'm rambling again....it's my age you know!

Andrew, my point was that, two species mentioned on your CB list, are in fact WC....the muelleri are in fact probably Xenopus laevis poweri, not that you are expected to know that, as you probably haven't even seen them. There is also a caudate on the CB list which is also WC.
My personal opinion is that Caudata.org, being a non-commercial site, should not entertain adverts or links, directly or indirectly to Petshops.

Mike,
The list I receive has X.mulleri as being captive bred. You are correct I have not seen any of the mulleri myself as I don't have much room for holding stock so most is to order so can not vouch for them being of that species. The other species you mention I can not identify because the list on my site is correct to my suppliers list (please note I am only acting as an agent for Worcester Reptiles and the list is sent to me by them therefore I do not always get to see the wholesalers list) and therefore is correct to the best of my knowledge. Also I apologise for the fact that I have linked to my site but as a new member I was unaware that that was against the rules of the group.

    Dear All, I would appreciate some help identifying P. waltl disease and treatment. We received newts from Europe early November and a few maybe 3/70 had what it looked like lesions under the legs- at that time we thought maybe it was the stress of travel- now we think they probably had "red leg syndrome" (see picture). However a few weeks later other newts started to develop skin lesions (picture enclosed). The sender recommended to use sulfamerazine and we have treated them 2x and we are not sure they are all recovering. Does anyone have any experience with P. waltl diseases and could give some input on this? Any input would be greatly appreciated! Thank you.
