I've just read an article on albino frogs and I was wondering if they get on with any tropical fish or do they get the urge to jump on everything that swims past?
Albino aquatic frogs are usually African Clawed Frogs and yes these do eat fish. African Dwarf Frogs are much better and don't grow as big, but are not commonly found in albino form.
The African Clawed Frogs are great pets, but not a good idea to keep with other fish.
They are very fast and have very large mouths. I feed mine rosey red minnows and they can jump up from the bottom and swallow most of one faster than my eye can follow them. I just hear a splash and see the end of a tail sticking out. I've yet to see one actually get caught.
