Just thought I would post some of this info again for all those asking about keeping copperbands lately.
I had good luck with this one, except he liked to sample ornamental clams. You need to find a healthy looking specimen in the store and after its been there for a bit. You could tell almost with in days which ones we got in would be healthy.
If it was me, I would want to see them eating mysis first. Mine was a good aiptasia eater but also ate mysis and Marine pellets. After participating in a thread elsewhere, I decided to try fresh water clams for him. They are called Manila clams and sold in a bag, here at Superstore.
He/she, just loved them. I used the clip shown in the pic after attempting to recover half shells from the tank bottom. Kept the clams frozen. Took one out at feeding time, cut it in half, put the other half back and the other part on the clip.
All the other fish also loved this and lined up behind the copperband for the particles falling away.
Others have said this is one way to get finicky eaters to eat. Those of us whose ate aiptasia also, never seen any difference after they started to eat clam halves.
Now the big thing I question. Does feeding fresh water clams, induce them to eat ornamentals also. Most say no. Mine was already a clam nibbler when I started to feed the Manila,s so I cant comment on that and he/she never changed in that respect.
If no ornamentals are kept then no problem but if so, then keep an eye on them. Mind you Copperbands can turn on clams regardless.
So I hope this can be of some help.
