Anyone else find their clown loaches follow regular routines? I have a school of 6 clown loaches (each around 4 inches) in a 200g with a few large pieces of driftwood. They dug out the gravel to one side of the largest piece of driftwood to make a cave under the wood. They emerge about 7am each morning as I feed them around 8. They forage round the tank all day, or just lie in the shadow of a few plant pots. Then, at 8pm, they return to their cave. You could set your watch by them. Is this regular routine common to this species?
