I think anemones are one of those animals that a lot of think they just got to have to have a reef tank.They dont think about what it takes to keep one healthy.Or how much trouble they can be later on when they take up half the tank.(If the nem survives that long).
I kept my BTA for a little over a year.And it got huge in that year.Doubt very seriously I'll ever keep another anemone,unless I deceide to set up an anemone tank,and that aint likely.
