There is a third major food source for BTA. That is the direct intake of nitrates from the water column. It is how some BTA farmers feed them.
My BTAs will have both bubbles and long tentacles on the same anemone. The long tentacles clearly have more surface area to be absorbing light then when they are bubbled.
I normally do not feed MY BTAs at all. I have high nitrates(20-30) and some get food when I feed the fish. I did a little experiment on feeding BTAs krill a while back as a couple insisted feeding them krill would make them bubble. I was skeptical but it was easy enough to try. I started feeding select BTAs krill every other day for over a month with no change at all in their bubbling behavior.
IT IS CLEAR TO ME AT THIS TIME IT IS NOT ANYONE THING THAT MAKES THEM BUBBLE!
