"Clownfish are social animals" is an understatement
This short video from 2007 is an oldie but a goodie (back from the days when "regular" captive bred clownfish were still the norm). Juvenile CB clownfish will often ball up in what can only be described as a Clownado. We need to trademark that word.
Another Clownado! These beauties were bred and photographed by Dr. Sanjay Joshi.
