unfortantly we have the same problem here with people and aquariums.
gives me the s**ts to no end knowing people try raise amphibians when they dont know nothing about.
i went into a aquarium here where i live and the guy had australian banjo tadpole that had there front legs and was trying to find land to get out of the water and i told them and they didnt even seem to care. they have a fully grown australian Green Tree Frog about 7cm in length in a 6 gallon tank with little water and a tree branch floating in the water.
the sad thing was they wanted almost $100 for it.
