Not get them anymore because they can be aggressive and quite disruptive if your community is happy. Price is appealing but I just don't think it's worth the chance.

Ignore me!!! I was thinking of the Damsels I had. Chromis were fine, I just couldn't keep them alive. I've heard they are hit or miss.

Or my damsels stressed them to death.

With Chromis, you WILL wind up with 1 sooner or later.

They fight amongst themselves to form a hierarchy. Often results in death of “weaker” ones. I had 15 in my 240 gallon and they whittled themselves down to 2. I have heard feeding more frequently will subdue the aggression but I feed 5 times a day so I don’t know how true that is.

if u want 6, but 8 as 1-2 will die within the first month. i currently have 5 after starting with 7 about 1 year ago. having healthy chromis to begin with helps.

5 will become 4, then 3,2,1
Lots of disease with these fish lately.
Be fore warned.

Thanks for all the replies. May give them a miss. Go for Foxface and maybe copperband butterfly.

Yes that is correct. They can manage in a duo.
I have 2 as well for a few years now, but I started with 15 or so on a number of occasions.

Most all come in with urenoma and will need to be treated in a QT tank with chloroquine phosphate. Like mentioned above they will fish and slowly pick each other off until you’re left with a few. I had 30 and when I got rid of them there were 7 left
