Anyone ever seen nemo and the part where he has to go through the filter? My hippo tang failed doing that and now has this hole around .5cm away from its gills. The size of the hippo is around 2 inches, and it seems like it's swimming decently but the second I placed into the tank again, it crashed into a coral. Breathing rate seems to be increasing majorly as well. Any recommendations of what to do?
Nurse him back to health and make him fat!
