Maybe a snail or an African Dwarf Frog. They (AFD) like cooler water and are very amusing to watch. Whatever your friend chooses, it would be nice to put a small live plant or two in the bowl, as they add oxygen to the water, as well as giving a place for the frog /fish to rest while at the surface.ecnaj143 said:Thanks for the suggestion. I have another question. One of my work mates is stealing my idea, but his is actually smaller. Its like a 1gal BOWL. What would be a good fish. No gold fish tho.
