Fish that do not approach the surface sometimes work with African Butterfly Fish, but no guarantees. The ABF is an ambush predator, and a very effective one; I had a pair for many years, on their own. I once had them in with other lower fish (temporary need) and within seconds they had fish in their mouths.
My advice is to keep the ABF in their own space. And depending upon space to get more than one, they are somewhat social...distinguishing male and female is relatively simple (the anal fin is the guide), and a pair are interesting. But even so, they do not swim at all, except when food appears. They must have floating plants to "hide" among or they will be severely stressed. They also can jump out of the tank through any opening when startled, which I found could occur at night in total darkness.
