hey guys I've had my clown knife fish thats around 7 inches right now for a year now and i got him at about 3 or 4 inches. is it normal for them to be growing this slow? he usually hides in a little cave in the driftwood and only comes out during the night time to investigate my payara or at feeding time. is he growing slow because the cave is too small? all of the large clown knives I've seen don't have any hiding places and just swim around, so should i remove the driftwood? thanks any help is immensely appreciated.
