Ive had a green carpet for about 2 weeks now. Hes attached, hosted, and mouth has closed. He is in a position where to powerheads direct flow and a small vortex funnels water down towards the nem. Ive been placing pieces of silver sides by his mouth and he never eats them. Is it not hungry or is there something wrong? Or is feeding off food fromthe other fish when I feed. It seems to be doing great in all other aspects. During the day it expands to twice the size.
