I have a clown loach that is about 3 inches long. it is in a 10 gallon tank along with two other small fish. i have an air filter its a pipe that has bubbles creleasing at the top that rise to the surface. i just changed the filtration rocks in it. anyway my clown loach is swimming vertically just idling with its mouth at the surface. what should i do?
why does my fish swim up to surface for air.?
