thats a cool vid. I always see these little critters all over my SPS. my tank has been fallow for nearly 10 weeks because of ich so they are multiplying at an alarming rate. My fish wont know what to do with themselves when i drop them back in.
Although you have already stated that a wrasse may be sleeping at night when they are out and about, it will still help control populations during the day, lessening the numbers and likely decreasing the occurrences when this happens.
just a thought.
