I just got this little fella 3 days ago. He did not touch air after I got him home and did not when he was being bagged at my LFS. I have moved it a couple of times trying to find a good spot so it would get enough food in the flow. It seems to be working as my tank seems to have much less matter floating around. Is it dying? It had them when I bought it but am thinking it may be getting worse. Opinions?
