Wow I didn't know ccb eats majano too. I'd notice today watching all my fish as it swim around & caught my attention on ccb picking on majano. 1 of my sps base rock full of majanos colony as well ate all my feather duster:)too. So I don't have to use this joe juice to kill all these pests thanks ccb. But I've seen it picking on my brains & acans kinda worried about it now. But what's good today all majanos starting to disappear in my tank really hate these pests:)!
