My clownfish host my BTA at night, but once the lights turn on they aren't caught anywhere around it. Is this common for clownfish? Will they eventually host it during the day too? They've had the anemone for over 3 weeks now.
It may be a security thing, at night the clown feels safer when sleeping in the anemone. If it is threatened or insecure in the daytime or when the lights are on, it will probably go to the anemone for safety. just my .02
