Anyone had luck getting a copperband to eat? Mine was doing well, wouldn't eat any of the Frozen I put in the tank but he was grazing on my rock pretty heavy. I just put a yellow and a sailfin that were tank mates in a previous life, now my copperband it just chilling in the corner staring at the wall... Not sure if it's stressed from the new additions or if it's because he hasn't been eating. Let me know what you guys think.
