I picked up some Mastick for my Copperband. He will eat Mysis, but seems to wait till he finds them stuck on a rock or on the sand most of the time and I was just a little concerned that he might not get enough food that way especially as I'm adding a few more fish in the next week or so. Anyway I searched for a "paste" that I could rub on a rock and found Mastick. The CB went right for it and picked away at the rock for about two hours. (So did every Nassarius snail that could reach the rock. I'll place it off the sand next time.) Problem is that when I received the package I found out that it cost $15.00 for about a weeks worth of pasty food. Does anyone know of any reasonably priced sticky food?
