Any one had this problem with clown loaches not eating? I had a few tiger barbs in the tank, and I feed them with floating flakes, some dropped down to the tank base, but many were eaten by the barbs, but the clown loaches doesn't seems to be eager to eat, they just swim here and there and hide in the ornaments holes I placed in. What should I do in order for them to eat? Btw those flakes are suitable for all kinds of tropical fishes.
