Maybe I have the 'wrong' dither fish right now. I have 6 rummy noses that are always hiding, 6 fire ring danios 3 white clouds as well as 3 odessa barbs and 3 mollies. As I said, leftovers from previous setups LOL. I previously had 14 odessa barbs as my primary school and didn't really see any improvement with the clowns. I do think it may be a bit worse since I got big hossiena though. I think she was in too small of a tank with only 3 clowns in her previous life. In the year I've had her she's grown a good 2" and that's a LOT for a clown that was already a good 6".
I'm thinking maybe if I filter the light it will help. I just ordered some frogbit. IT's pretty bright in there right now. Also, if I add a powerhead for a spot with good current, it might help draw them out??
The tank is in our living room, behind the couch. My Shih Tzu sits there on the back of the couch all the time and they don't even notice her, but when I sit on the couch BOOM they all take off.
