Someone put Chromis in the corner

[cwiggins]

Hi,
I'm seeking advice. In Feb. 2016, I purchased 3 Blue Green Chromis. I'm down to one. The Chromis that is still around was the aggressor of the bunch. In Nov. 2016, I purchased a pair of Maroon Clowns and in July of 2017 I got the clowns a BTA that host them now.

The Chromis is currently in the corner of my tank and I don't know how to help it. (Been there for 2-3 months now) I think it's stressed bc. my Maroon clowns are territorial. The clowns seem to own the right side of the tank with their BTA. My diamond goby and Lawn Mower Blenny can visit that side of the tank. As well as my Banggai Cardinal and Ruby head wrasse (but he swims quickly past the clowns or goes behind the rock to avoid them)

Is the corner isolation behavior exhibited by the Chromis stress or something else? (He eats great at every feeding) Can I somehow get the Chromis to realize it has the left and middle of the tank to swim in? Do I have these Maroon clowns in too small of a tank to allow other fish to live happily?

Thanks for any advice you might have!

another chromis is doing the aggression,,Ive read an article about chromis aggression on the forum before.
If you buy a group of chromis,,eventually youll only have 1 or 2 overtime..
I have 3 tanks on my system,,all tanks had groups of 10 chromis each,,sadly I have 2 in one tank and 1 in the other two tanks...mostly all chromis ended up in the corner like yours and moved on to the after life..

But I only have that one Chromis in the tank now. The other 2 died because of the aggression from the one that is now in the corner of the tank.

Karma??? Just kidding! I had this issue with a damsel, unfortunately, it was too far gone by the time I caught it. Is it in the corner after lights out maybe you can catch it when the lights go out?

Funny Yes, it is in the corner even when the lights are out. What would I do with it when I catch it? Maybe I'll try moving it to the other side of the tank and putting in a tank divider for a little bit.

Mine was doing the same thing. Just put him in the frag tank yesterday, and he looks ecstatic about having a space to himself. I'd either re-home him, or whoever is picking on him.

Maroon clowns are mean

The chromis has been fighting for its life against the other chromis.

I would remove the chromis.

Happy reefing!
