My Endlicheri bicher is mellow. Laying around at the bottom of the tank. But, when it comes to feeding time he bites and tugs at the stingrays to pull them off the food. He looks like a crazed water snake pulling stingrays away and taking food from under them
My african butterfly fish sits still all day sulking, but when he's fed he comes over, snaffles the food and then goes and sulks in his corner again. He's just grumpy.
My silver dollar can be quite moody at times other times he's fine and will feed from my fingers! I'm starting to wonder if its not a he but a she going on its mood swings
