View Full Version : Do your Chromis still school?

12-01-2012, 12:55 AM
Just wondering...

I want to put 5 chromis in my tank. I want to add them as they will move around a lot... and school.

I hear people say they stop schooling and why bother.
If you CURRENTLY have chromis, are they still schooling?

Never really have schooled

Do you have an active tank? Some people say a more docile tank gives the fish no reason to school. So I hear.

I wouldn't say my tank is docile but any aggression is never directed toward them. Tank mates are : powder blue tang, one spot fox face, copperband butterfly, cleaner wrasse, 2 clownfish, and 3chromis

I had half a dozen of them when my 90 was set up. 2 or 3 of them would hang around each other from time to time but that was about it. My tank was pretty docile, nobody chased after anyone. I had a foxface, yellow tang, 2 clowns, royal gramma and a solaris wrasse in the tank.

I have had up to 13 chromis that always schooled. They moved in unison like it was an Olympic event. Now the remaining 9 (little suckers jump!) don't school in the same way. Sort of a loose unorganized formation if at all. The change happened right after I gave away my large monodactylis argentus. My guess is that they don't feel as threatened.

I have six and always stay together as a loose group.

Started with 10, after 2 months they killed off each other. Now there is just one.

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. :neutral:

I have 7 and they are always in the same area of the tank but never really swimming as one. They schooled much more in the beginning. Couple tangs and a couple angels as mates plus several others

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 :)

My Chromis school at times but not very often. They tend to gather together when my Achilles tang thinks he needs some excerise and chases them around for a while. He doesn't seem to get aggressive, just chases them in and around my sps corals.

start with 3, schooling and now only one because he killed others and very aggressive at feeding time. He won't be on my new tank for sure.

I dare anyone to says their fish school in their aquarium to post videos/pictures.

Personally, I think "schooling" in all but the most mammoth of captive environments is something that LFS' make up to sell more fish.

I could be wrong, but I'd like to see some photos.

My group of 7 were always in one pack or two smaller packs.

Perhaps Snappy can chime in about what they're up to nowadays.

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).
