I was watching my mimic tang and hippo tang chase bubbles in the tank last night. It dawned on me that I have nothing in the tank that really causes bubbles. So I watched more closely. The Hippo would go to the top, suck in some air and then blow it out his gills. Then both he and the mimic would go on a bubble chase. Does anyone else's fish do this? It was honestly the weirdest thing I've ever seen a fish do!
