Green Chromis question

[Nydus]

I have 2 green chromis in my 105G tank, one chases the other one around then they start "kissing". Are they just playing or is one bullying the other one around? Very entertaining but I would hate for them to bully around any new smaller fish I decide to introduce at a later date. I plant to have a passive reef tank.

They're attacking each other. The kissing is a form of aggression. Generally it's better to keep Green Chromis in schools because one feels lonely and two fight. I don't know what your fish load is like already but if you haven't had these chromis for too long you could probably add two or three more to make a school.

Hope this helps.

Iv had them for 2 weeks now and they just started doing this. I only have 2 cardinal fish and one yellow tail dansel in at the moment. .. do you think its too late to add 3 more chomis to make them school? thaks!
