An Aquatic Froggy question ( verry important)

Question

I have an albino clawed frog in an easy to care for 5 gallon tank, I keep it verry clean and feed him often, theres nothing he can hurt himself on in there and I'm verry confused...

So this morning when i fed him, he had both his little hands but when i can home from my sisters, I noticed his left tiny hand looks like its been knawed off or something, I dont know what happened. but its gone..and i looked in the botton, ( i have clear plastic rocks, easy to scout about in ) and his hand is just... gone.

what could have happened and do frog limbs grow back, will he die, do frogs go into shock.

please answer :( i feel just awful for him)

Answer 1

As gross as it sounds his tissues could be rotting. I would go to the pet store and look at the medications they carry, and try to find something to treat him.  

Answer 2

it could be rot but he also could got it trapped and pulled it off or even bitten it off by himself (i assume he's in a tank by himself) i would get him checked ova by a herp vet keep a eye on the wound and clean everything in his tank (and the tank itself)
