Tank has been set up for 6 months, BTA is about 2 weeks old (but has been fine till recently). It has been acting this way for the last 2-3 days. Cranky in the morning fine in the afternoon, evening, and night (even with lights off). Everything else is doing fine. He found this spot day 1 and has not moved.
Maybe I am worrying over nothing... maybe it is just not a morning anemone.
