Should I use my 56 zoa colonies as food?

[Delphinus]

Yeah, the first trick will be getting him to accept that what you offer is actually food. There are the occasional CBB's who take to flake or pellet, but they are rare. Mine never did, but at least he loved mysis so it was easy to get him to eat that everyday. Another treat I'd give him was mussel or food clams or oysters, but tangs will love that stuff too so make sure he gets some somehow.

Just basically keep an eye on your acan's. I never pieced it together at the time because I never saw him pick at them, but they stopped flourishing and started receding and there was no other reason for it - now that I think about it, I think it was happening at night when they had their feeders out.

Zoanthids were fine though. Good luck with him! This is one of my favouritest kinds of fish, I have a soft spot for all butterflies but CBB's in particular. Mine learned to recognize me as a provider of food, I could cup my hands around him in perfect trust. It absolutely broke my heart last year when he suddenly displayed a weird lesion above his eye one evening, and he was dead within 4 or 5 hours of my noticing. A few months shy of 3 years I had him.

Anyhow, definitely a beautiful little fish. Good luck!
