Chromis Kissing

55 gal with plenty of rocky overhangs. 2 already died...

 

I am guessing your cycle has completed and params are all good. In a tank that size you should not have a problem. I had 7 in my tank with little problems. I think I did loose one to aggression because it was hiding all of the time. How long have you had the fish?

Sorry about the loss.

 

same thing happened to me with clownfish....than they paired the next day...ever since they dont leave each others side

 

How often do you feed? Chromis should be fed at least twice a day. This might help lessen the aggression.

 

I've noticed when my fish are hungry, and around feeding time, they have some serious aggression issues. But all other times of the day they get along really well.
