there are about 30 fish all together in this room. some in the under filter bit. its at were i used to work nd i tryed to ask if i could buy them all but they wont let me because they have been in coldwater and there tropical and he is not happy selling them to me. so they are just going to let them die. in these fish tanks there are platys, headstanders, an angel fish that has only an inch of water in its tiny tank!! and tetras nd danios. so they are just going to leave them there and not going to feed them or anything. is there anything i can do to save the fish before they die??
