I currently have a trio of Clown Loaches and they are having a fun time with each other swimming together. I just added two more clowns to the previously one I had and I realized that the one that was in alone for a few days is pretty pale in comparision. Does anyone have any ideas or will it just take a couple weeks for him to adjust and get his color back? He has been eating well so I know he's getting food. My 2 firemouths and severum have good colors. Could it have anything to do with him being alone by himself for a few days. I've only had him for about 5 days. Any Ideas?
