Thanks Chin, tried this already, my CBB would not touch it.

Day 8 and still not eating! The CBB is thin but does not appear stressed. It is adapting to the new tank. It occas picks at the liverock but I don't think it is eating anything. All the aiptasia is still present. It didn't touch the clams in the 1/2 shell. I have tried 3 brands of mysis shrimp and two brands of brine shrimp also without success. I will keep trying.

Did you try adding garlic ? How about blood worms ?

I tried soaking the mysis and brine shrimp in garlic and adding garlic to the tank during feeding with no luck. I have not tried blood worms but will see if I can get some locally.
Thanks for the help.

Update
 

Well it is 21 days today. After 2 weeks not eating I finally found some blood worms locally and he likes them. I have been adding garlic and Selcon. I don't know if he would thrive on just blood worms? I am going to try tubifex worms next. I am scared to move him into my main tank with several damsels and tangs as he likely will starve if he only eats worms that are lying on the sand.

You can try adding in other food stuffs to the bloodworms and serving them togther, to see if that illicits a response. Sometimes you can get fish to acknowledge that one item is food, and generalize that knowledge to another item (seeing it as food), by serving them together.

Have you tried mixing in any dry foods, such a cyclopses (sp?), pellet food, etc.?

I'm just wondering if maybe adding it to the main tank would actually improve its eating habits. I know by watching some of my fish, that they learn what/how to eat by observing the other fish eating (e.g. my chromis are now constantly pecking at the seaweed clip). If it was eating frozen brine shrimp while in a "community" setting, perhaps it will do so again once amongst other fish who are doing the same.

Just a thought!

Thanks for the advice. There is also a few green chromis in the tank that eat everything. The CBB watches them eat but doesn't seem to increase his desire to try these foods. I have tried frozen and flake cyclops without success. I will try adding different foods at the same time as the blood worms.

Have you tried an oyster or clam (live oyster or live clam from the supermarket if you have one that sells that sort of thing, it sure is fun going up and asking for "one oyster please" :lol: )? Or a mussel ..

I buy about 4 or 5 at a time, throw them in my sump, and about once a week I'll crack one open and throw it in the main tank.

Probably not great for water quality, but .. well, at least he's eating something this way..

I have tried cracking open a clam with no success. I was too embarrassed to ask for just one clam, so I bought half a dozen instead. Maybe I will try muscles next.
Thanks
