well heres my dilemma... i had my jd since he was 2" now at 4", he still just hides in his little "house" and rarely comes out. when i feed the other fish, they all come up to eat except him. he will come out and just watch. the only time he eats is when the food falls to the bottom. the weird thing is hes the "boss" of the tank so i would think he would be roaming around the tank.
