As far as I know from what I've read they do stay in a school unlike chromis. I hope they will because this was the whole reason I wanted these guys.

I had 4 and I found they tend to pair off and rather then school together they just hang out in the general vicinity of each other.
They don't swim very much and they probably wouldn't of noticed if they were in a 20g instead of my 175g but the colour around their eyes is the most amazing blue

My chromis still stick together after about 4 months now. All 9 are still with me (none have been killed) and you rarely see one go anywhere without the rest except sometimes at feeding.

Not sure why mine are so 'close' or feel the need to school but they do.

Interesting. I've had not much luck with keeping bigger groups of chromis. I've had up to 15 at one point and the number always ends up at three.. I don't know what it is but when I add more.. it always settles at three.

Yeah thats what everyone told me but this is the second time I have kept a larger group and so far all are still around and the first time I tried years back, only one died. I guess I have just had good luck with chromis.

I've had 12 for about 3 months and they school probably 50% of the time. I also have not seen any pecking order in the group; no signs of chewed fins or aggression. Couldn't tell you why.

good luck with them, they have pretty short life span, somewhere between 18 - 24 months. But otherwise beautiful fish!

They are a very cool looking fish but very timid and not too bright. I used to have some and it's the only fish I have ever witnessed being nabbed and eaten by a nickel sized aptasia. If you have a non aggresive tank I'm sure they'll do great. I wish I could keep them. For the record my chromis tend to school the majority of the time. I have 16 of them in my 400 gal and they sometimes split into 2-3 schools but usually stay all together.:smile:

I always tend to hear about chromis not staying in a school as they get bigger, guess that's not true. My tank will be non aggressive & I have no apistaisa, thank goodness. I want it mainly sps and I have some small shrimp species, pom pom crab, porcelin crab, a pair of ocellairs clowns and maybe one other peaceful bottom dweller so all should be good.

Dawn that sounds like a nice peacefull mix so those cardinals so do great. As I said I wish I could keep them in my reef.
