again what are all the fish in the tank, tank size, the chaser, the chased.... amount of hiding spots, size of fish... Need a little more info to really be able to help...
well i have about 8 rocks the has holes thru them its a 72 bow chipkoa.blue peacock(female),1 kennyi, 1 duboisi something called ice blue,2 lace cats and 3 small plecos.the chaser is a mix
ok what do you mean the chaser is a mix
with kenyi's and is it the red top ice blue mbuna you are talking when you say ice blue even these guys are pretty aggressive towards other fish
i used to have that problem until my wife bought the great equalizer! if you dont have a great equalizer of your own, add lots of stacked rock. I have also found that overstocking african cichlids decreases aggression. my 150 has 30 africanses, 3 plecos and an eel. Also keep them well fed. I had a problem last week where i lost a big portion of my beneficial bacteria for unknown reasons so i could not feed the for a while. 3 got eaten.
