I have a major aggression problem that suddenly erupted in my tank...over the past week or so (2 fish dead and 2 hiding/not eating). I am trying to find the culprit and fix the problem. I have a 77 gal tank with 4 acei (1 holding), 4 yellow labs (1 hides in the top corner), 1m and 1 f msobo deep (newest additions...I got them end of Mar), 4 yellow rock kribs (2m,2f...1 f hides in the top corner), 3 syn petricolas.
My demasoni has completely disappeared and 1 m msobo deep was killed...shortly after he started showing male colors.
My best guess would be the male msobo or the dom m rock krib as the aggressors. I havent seen any chasing or bullying except between the 2 male rock kribs...they really scrap badly and I need to get rid of one of them very soon.
Do I get rid of the dominant male rock krib or the other one?
My f rock krib has taken to hiding bihind the heater and has stopped eating..could I put her in a breeders net in the tank? or would that even work.
Do I have too many fish in the tank...or not enough?
