I picked up an awesome looking male GT a local fish event friday night and he doesn't seem to be doing very well. He is solo in his 55g tank and has been totally hidden all weekend and when I catch a glimpse of him his color is totally gone. Water parameters are Ammonia 0-0.25 (some where in between but low), nitrite 0, nitrate around 5ppm. I know you want 0 ammonia but the tank should be cycled properly as I got some well established filters from a local club member at the event. The fish also won't eat at all so I have to remove the food a little while after feeding. Is this just normal acclimation? Anything I can do to help him along?
