I’m sure this is a stupid question, knowing how delicate nems can be. My clownfish, which I’ve had for about 4 months, have finally paired up and as of the past 48 hours, started hosting my BTA. It’s a relatively small nem, probably 1.5-2” diameter when open. Tonight, I witnessed what I assume is them “getting ready for bed” and being rather rough with the nem, both head-butting it. It’s foot is in a hole in the rock, and if it needs to, it can retract into the rock work. I went out and purchased a second BTA to hopefully share the load, once it acclimates and adjusts obviously. Do they only host at night, hopefully allowing the nem a chance to heal, or should I keep a cautious eye out? Again, sorry if this is a dumb question. Though not new to the reef scene, this symbiotic relationship is new to me!
