lol no africans dont go in 10 gallon tanks. "Africans" is such a broad term. do you mean lake malawi (mbuna), haps, lake tanganyika or victorian? shellies might do as a pair in a 10 gallon-but i even doubt that. i dont keep lake tangs so im not sure.
how about a 35 gallon tank to start with? go with shellies or a small group of dwarf malawi species fish...
can you get a bigger tank? or are you stuck with a 10 gallon? what species of africans catch your eye?
