Moving this to the reef discussion section....
In my 24g I had a bubble tip for a couple of years that grew, split, and kept on growing. Ended up taking both of them back to a LFS due to them stinging too many corals. And this was under CF lights.
Now in my current 75g tank, I am not having a lot of luck with anemones. My once large bubble tip has shrank, and then split into two smaller anemones. They are under MH, but still do not have a lot of color.
