When I wanted to keep featherfins in a 72" tank I was told to give them the whole bottom.
I would want the Cyathopharynx, LOL. But at the time I was asking about Opthalmotilapia along with fish like calvus and julidochromis. What say you?Well sure, they'd love that, but it is not necessary, especially in a large tank. Ophthalmotilapia will coexist quite happily with Xenotilapia; large Cyathopharynx may be more problematic.
