Are there any indications of when an anemone is going to split? I have read that they crawl into a dark area in the back of the tank and do their thing. About a month ago, my rose BTA moved to the back of the tank behind some lr and stayed there for about 8 days, and then moved back to where it had been and has seemed just fine since. I was hoping that it would split but it didn't do anything. My water parameters are pretty good except my nitrates are a little on the high side (about 20 - 25). Could this be the reason?
