Question: Salamander ID and Health

[Charlotl]

I got three "Water Dragons" from someone who supposedly kept them in a shallow aquatic environment for at least a year after they morphed and should have been terrestrial. From reading this forum I have heard that doing things like this is really bad for them and decreases their life span. I am new to salamanders so I know very little about the effects of their previous situation. Are there certain health problems I should be looking out for or any way to estimate how long I should expect them to live?

Most "Baby Dinosaurs" from (you guessed it) Oklahoma were IDed as tiger salamanders I was wondering if one of you could confirm that they are. Could you also tell my why (or why not) you know what they are? Most other posts I found didn't give explanations and to me all mole salamanders look the same. The three are labeled as A, B, and C in the pictures. B is 7.5 inches from nose to tail, A slightly smaller, and C at least an inch and a half longer.

They are all tiger salamanders and should be housed in a fully terrestrial tank with only a water bowl for water if anything.
Here is a caresheet that should answer some questions you may have:

That was the first thing I read after I got them. They have been in the proper environment for about a week and are doing great. Thanks for the link anyway though. Also, can you explain why you know they are tigers?

Most "water dragons" or "baby dinosaurs" end up to be tiger salamanders, its pretty common.
They also have typical patterning for some of the subspecies, I don't think any other mole salamander looks like it, at least to me anyway
