This is the group of fish I know least about, sadly. I was never that interested until recently. Just looking for any advice and wisdom on keeping these guys. I don't care which lake is suggested, but Tanganyikan interests me for their behavior more than colorings. What would be some good beginner species, and minimum tank sizes (can't be huge)? I'm aware of the aggression, rock work, and alkaline water. Any do's and don'ts?
