i dunno, maybe they are the same thing, but i have always seen them as African Dwarf CLAWED Frogs... *shrug* maybe that are in the same family? But they dont get big, and i have only ever seen mine eat a tetra fry that accidentally snuck into the net when i was getting ghost shrimp. lol, didnt notice it till after i got the shrimp in the water, and then it was too late.
But i digress! lol, i have looked at that page, but i still cant tell... I dont have another one to compare to, so i dont know how long the 'tail' is supposed to be, and it rarely ever holds still long enough for me to look under its arms. ;^;
