That's what I thought about the discus. As for the Africans, they are mostly little babies. Most of the tank is less than half an inch, and a few inch sized guys. The same with my centrals. They are a little bigger but still young. I figured that's why they hide? Also I have a ton of deco, rocks and drift wood in both tanks to keep aggression down. They have lots of hides, so I don't see them much but they don't hurt each other As for the tank suggestions, I agree a lot of small active colorful guy would look nice. Tetra make me nervous bc I've heard they are nippers?
