Aptasia surprise.

[Crotalus]

I've put peppermints, berghia, and a file fish in my tank. None of them ate the aptasia. I don't have a lot of them, but I've been worried about them taking over. So about once a week I make kalk paste and cover the 3 or 5 I find in the display. It's a hassle.

Then I noticed an explosion in the sump. I had tried to kill the dozen or so I saw in there by draining the sump and spraying 12% peroxide on the ones I could see. The result, 3 weeks later there were 50 or more in there. Some were huge.
I had bought the file fish specifically for that reason, so I caught him and put him in the sump. Eat aptasia or starve. A week later they were all gone.

Now I don't know if I should put him back in the display or just start feeding him in the sump.

You’re answer is a kleini butterfly BUT IT MUST BE THE blue face- Not yellow version which will eat softies.
The blue face is pretty, friendly… eats all foods flake and frozen, eats aptasia like candy
