Can Poor Flow cause Bleaching in BTA?

[stevetcg]

I had a beautiful 8" BTA. It was happy and healthy with his GSM pair for months. Then he split.

2 weeks later I changed the filtration on the tank. The water quality is better (0/0/0/8.2) but the flow decreased dramatically.

Now both BTAs are bleached badly. Is it possible that the diminished flow is the cause?

Can you post some pictures? Splitting can be a sign of stress as well as happiness. Given that the anemones have bleached and you say water quality is better, I'm going to venture a guess and say that the anemone split due to stress. Bleaching is also a sign of stress. I have not encountered an anemone bleaching due to lack of flow, but that's not to say it isn't possible. You should increase the flow, and target feed the anemone to help it get more food. Also, how old are your lights? what are they? color, watts, etc.

Bleaching bta isn't from low flow, if it's low flow they'd move closer to the flow themselves.

The BTA is stressing out, or lacking nutrients, thus losing coloration.

What are your parameters and photo-periods?
