As I'm watching my mixed tank of young L. Caeruleus, Auloncara sp. and Haps, I've noticed my fish seem to really enjoy brushing their sides against the sand. My guess was that it was a behavior inherited to remove parasites in the wild. Does anybody know what the real reason is?

The behaviour is called flashing. Could be a change of water conditions. If you did a water change recently or added different rocks that would explain it. It can also be ich. If you see little white spots like grains of salt on the fish body or fins, than treat for ich.

I knew it wasn't ich, I just had never heard of flashing before. I did a 40% water change and rescaped the tank. Is flashing as common in the wild?
