Question: Need a little help identifying my tiger salamander larvae

[BIGBODYBEAR]

I am new to the world of salamanders & i bought a tiger salamander larvae about 5 months ago , i got it at 5 inches ,it is at 7 now , im not sure whether its a male or female , it has a small little hump under behind the back legs but not a big one like ive seen online , also i would like to know what species do i have because when i bought it , it was called just "water dog" but i want to be sure , thank you in advance

ps. i attached a couple of pics to see if anyone can help

I'm no ambystomid expert but without adult coloring or locality information, its probably not possible to tell what species it is.

If you're new to tigers check out the Caudata Culture Articles Tiger Salamander 101 and Tiger Sal Caresheet.

I would advise you to remove those pebbles as soon as possible. The risk of your salamander swallowing some of the gravel is pretty high and impaction can be fatal.

Edit: Your animal will most likely be unsexable until it reaches sexual maturity.

You won't be able to sex it until in morphs. And no one will be able to give you an educated guess on the species until it morphs. Some you can tell what species they are, others have colors and patterns so unique that it keeps what species they are a secret.
