Oh gotcha, I didn't know if it was a widespread issue or not. I like the way they look and your tank looks good with the butterfly fish.That's just the thing, everyone overblows how butterflies eat any and all coral and if you put them in a reef you're basically throwing all your coral in the trash. I'm saying that's clearly not the case. Just look at everything in my reef in that video. You have to know butterflies from each other so you can plan your coral stocking accordingly.
