I purchased my first fish for my 55 on monday and I got 4 electric yellow labs. They are only about an inch long and thats really what I wanted so I can watch them grow. Everything was good until today I noticed that one of them looks pale and seems to swim sideways along a flat rock every once and a while, like he is itching himself. Although he is still very active with the other ones especially when eating. He seems normal except he is'nt exactly the same bright yellow like the other ones and the occasional rubbing along the flat rock. Could this be ich? I don't see any white spots or anything else on him except the different color and he is the only one acting like this. Anyone got any ideas? Thanks.:help:
