Lol,
I actually spotted 2 aptasia yesterday, U think the CBB can't access the foot of the aptasia, so they recluse when it's close by. No worries, but otherwise, it's nice to see those ugly pests being harassed, lol
Yep, it's good they know who's Boss! I had a couple underneath some rock work that he couldn't get too. I added an aiptasia eating filefish and he can get into those areas and take them out.
I see your response to Alex about eating flakes. It took a little while for mine to eat flakes. They are very finicky eaters until they get over it. Once you really get them eating then they will go after most food other fish eat. Mine wouldn't touch anything I gave it except for Masstick and also Blackworms. They are obsessed with Blackworms. My LFS sells live Blackworms and I started it eating off that. It used to come right up to the turkey baster to eat them out. Then I switched to freezedried blackworm cubes. You can get these off Amazon and all the fish including the CBB go for these. Eventually he started eating flakes and hasn't looked back.
