Thought I would tag along on this thread. I bought a big CBB from my LFS about a week ago. I saw him eating brine aggressively at the store. The first day or two, he would eat a few frozen brine shrimp, but was shy - food would fall right on top of his head and he'd just sit there. The next 2 or 3 days, he was much more aggressive - actively seeking the brine shrimp and eating quite a bit. We use a turkey baster and spot feed such that food can definitely get near him. During this first 3-4 days, when he was eating the brine really well, we didn't notice him eating any aiptasia (that's why I got him).
The next day we saw him cruising around more, and he has definitely gone to work on the aiptasia (yay!). I have seen him eat little ones and work on big ones. I see him all day picking at things. I love this fish!
Now yesterday and this morning I noticed he's not taking the frozen food as well. He'll just sit back and watch it fall - eventually his tank mates will get it. He will go after a few pieces, but then spit out, take a bite, spit it out, and then finally keep some shrimp in his mouth. It's noticeably different than from last week, when he would attack the food. I've tried brine and PE Mysis - he takes to each about the same. He is eating some, but not as much.
My wife thinks it might be because he's eating more aiptasia, maybe he's just not as hungry. That makes sense to me. I'm just a little worried, because I know how hard it is to get these fish to eat, and it made me so happy seeing him go after the frozen food at the beginning. I'd hate to see him stop eating. It's almost like he wants to eat, but then changes his mind. (As opposed to my mandarin who doesn't even appear to be aware of any frozen food around him).
Is this a bad sign? Will a CBB that was eating frozen food suddenly stop? Will he go after the frozen again once he clears up all the aiptasia? There is a TON of CBB knowledge in this thread, and I'd love to hear your thoughts on this. I'd love for this fish to make it because (a) he's a beautiful awesome fish and (b) I've always wanted a long-term natural solution to aiptasia.
Any thoughts?
