During a water change about 3 weeks ago something very weird happened. I usually siphon out 4-5 buckets of water which is roughly 35-45% of the water. After i siphoned out the 5th bucket 3 out of the 6 harlequins immediately and simultaneously turned upside down and laid on the substrate. I've never seen this happen before and it's the weirdest thing to watch. The other 3 stayed schoaling while these 3 laid on the bottom and were moving slightly. After about 1-2 minutes they 1 by 1 gradually turned the right way up. 2 re joined the schoal and 1 stayed by itself for a while. Since then i haven't seen any other weird behaviour. Any ideas what the hell this is?
