coral beauty ....

[blueyota]

Well my beauty started picking at my coral:cry: but the weird thing is as soon as he started picking at one all of the acros pulled there polyps in and havent been out....Till now!!! caught the little bugger and put him sump side ..and within 5 mins of the beauty being gone all the acros started to extend again ...
The coral beauty must put off some weird energy or smell that the acros pick up .....

I expect that a stressed acro releases compounds that are detected by other acros. I'm willing to bet that something similar happens during mass spawning times.
