Missing Chromis School

[Cod Fish]

I added a group of 5 blue green chromis to my tank 4 days ago and all but one have disappeared. I did a long drip acclamation and they seemed happy when I first put them in but now there is just this lone chromis swimming around for 2 days now? Are they know for hiding? Or are they most likely doomed? Weird

I don't think chromis really school together. Since i added 10 a long time ago ti always seems to dwindle to like 1-2 over time.

That seems to be the experience of many people

Yeah but they have dwindled to 1 in two days

That one is the winner. You may never find traces of the others.

How long did you think it would take?

 

[Cod Fish]

so i take it this is pretty normal. Should i bother re stocking?

Not with blue/green chromis!

they don't really school and are brutal to each other...I added 10 to my 250 and had 1 about a week later...and the one left is tough...

Sometimes drip acclimation can cause ammonia burn http://www.reefcentral.com/forums/showthread.php?t=1939508

true true

I had around 15 starting, then after 1 month it was down to 8, then after 1 year down to 3, now its down to 2 pair. They are very brutal towards eachother, especially when they mature. I watched one attack another like a stealth bomber, repeated dive bombs on one target, in quick successions.
