That's some sobering statistics. It makes me think that indeed the importation of wild-caught fish needs to end altogether. That's simply unsustainable practise.
My CBB is now about 2 years old. I would have to say that the people who are beating themselves up in this thread should not do so, I don't think the problem was your "skills" per se but something further up the retail chain. I didn't realize how horrid the hit to miss ratio was with this fish, I just picked up a small guy one day at the LFS. Very picky eater but is easy enough to satiate with a few staples such as mysis, aiptasia (I let them run rampant in one tank so I can move rocks over once in a while), and grocery store shellfish. Unfortunately everyone loves mussels and oysters so it's hard to make sure he gets enough, I stick it in a narrow crevasse that only he can fit in and so on. Anyhow point being I don't think I do anything special and I don't consider my husbandry at a level any better than anyone else. I think the source must be a factor here.
Anyhow sorry to hear how bad it really is out there. Does make me have some second thoughts about what impact the hobby is having.
