Do your Chromis still school?

I have 10 that are schooling but they have only been in the tank for 2 weeks.

As they got bigger, they started to get agressive.

I have and they usually do their own thing... From time to time , a couple may decide to hang out together in the middle other than that I would say no.

I have had as many as 13 in my tank and they just end up killing each other off over time, down too 3 now... they schooled in the beginning but now they just chase each other around most of the time instead of living in harmony

I have had 6 since August. They keep fairly close together some times spreading out but then tightening up.

I have had mine in the tank for 18 min now and they have schooled the whole time

[Evilweevil]

19 min mark they are no longer schooling lol

[Delphinus]

Mine only schooled when very small. I started off with 6 I think, although 1 was a big old guy I had for a few years already.

I like the look of these fish especially when they school but even still by themselves, I just like their colour. So when they stopped schooling I didn't mind so much.

But like many many many other stories I hear of these fish, mine eventually started getting nasty to each other. And one by one, they die off, or jump, and in the meantime you see them with all with torn fins or scrapes and bumps, or just spending their life hiding out in a hole.

I don't think I'd ever bother getting any more, pretty colours or not. I can think of a couple other fish species that would do better if the schooling fish effect is what you were really keen to observe go on.

I saw the same thing with my batch from the 97. All the ones from the 404 were pristine and gorgeous. Hit or miss maybe (or the big tang tricked them into thinking they needed friendship).
