Well I finally figured out why all 4 of my acans have been closed for several days. I sat and watched tank today just to see if anything was bothering them. Well let’s just say my Foxface,flame angel and 2 bar rabbit fish began picking at them. I’m sure this has been going on for a while which now explains my deflated acans. Ended up taking every colony out and putting in my breeder hopefully they like their new home.
