I have had my Copperband for 1 month now and am starting the think if what I am feeding is sustainable in the long term. Currently, I feed chopped clam, oyster and scollop which I push into cracks in a rock that is lowered into the tank with a piece of fishing line. The Copperband devours it instantly and looks nice and fat, although I am wondering if this could be considered a complete food or do I need to supplement its feed somehow to avoid future issues. TIA
