I went out of town for 4 days and came back to a few problems with my tank. The one good thing I noticed was that my 5 inch bta split into 2 healthy anemones. Then 5 hours later I noticed I have 3 healthy anemones. 2 do not have a mouth yet but is it normal for a BTA to split and have more than 1 split. I've heard of it going from 1 to 2 but never from 1 to 3. Is this normal?
