Can ONE Jewel go with my Mbuna? I know they're African and are a pretty tough fish so I thought it would do okay in my tank. There are Yellow labs, a johanni, electric blue, a socoloffi and a cobalt blue but more to come. What do you think...yay or nay? The Jewel I like is about 1.5-2inches big and the biggest fish in my tank right now is about 2.5 so they'd all be about the same size. Thanks.
