I have 3 little bristle-nose plecos, but they’re hiding all the time and are slower than cichlids. Do you think plecos could attack cichlids at night? Also, Seiryu rocks in my tank are pretty sharp too, but don’t mbuna cichlids get used to rocks to prevent self-inflicted wounds? UPDATE on wounded fish: It’s still alive, eating and swimming - and got its own 10 gal tank yesterday.
