My Copperband has been in for 3 months, with a slightly larger yellow and kole. The yellow was definitely more aggressive, kole could pretty much care less. He wouldn't strike, but he would flash and show his dominance. It took about a week or so for him to accept it. Since then everybody has been fine. The Copperband was also eating frozen s. shrimp at the LFS
, and still eats it and Mysis. Between feedings he grazes, mostly on pods
and I think it's some form or Carribean Tube worm? Which is what I was hoping, the tube worm is becoming pest-like! Under yellow in pic. If you know what it is, please let me know. If not, I'll put a better pic of it on ID. Anyway, love my Copperband, and you probably will too! Good luck with the feedings!
