Clownfish and Toadstool at Night

[jjjoey]

every night as soon as i turn my lights off
one of my clowns goes straight into my toadstool
he stays in it until i turn the lights back on, he bites at the other clownfish if it tries to come inside the toadstool
i was wondering if my clowns are not getting along and
will my clownfish ever host the toadstool when the lights are on?

My guess is yes. If she is using it as a night time host, she will likely soon use it full time. She should also let her partner in at some point. She is just showing her dominance and making sure its all in order
