Is this what I think it is?

The anemone that strikes fear in the hearts of reefers everywhere?

It's on a large plug leftover from a frag I purchased. It's been in my tank about a week. Note the other small polyps.

Should I remove these guys immediately?

Aptasia on the left - I can't really make out the bottom right, might be algae.

Thanks.

I think I see tentacles on some of the other polyps so I'll assume they are as well. Guess I should trash the whole plug or should I remove the anemones as I identify the polyps?

As I said, the plug has only been in a little over a week and it's most likely what they rode in on. Should I assume the tank is contaminated by now? It's been up and running for about 7 weeks.

I can't make out the polyps on the upper right - I guess they could be either. Can you get a better pic?


I would definitely remove the anemone by any of the common methods - kalk paste, burning, epoxy, etc...

This is a better shot. I pulled the piece out. The bugger was superglued after this pic was taken. A snail came along to witness the execution.

The other polyps look different than the anemone so they're probably ok? I don't see any tentacles on them. They are closed but I'll also keep an eye on them when they open.

0083 = apstia without a doubt

Looks like aiptasia to me. The polyps look like some kind of common palythoa - harmless except they can overtake some other corals and come in a whopping variety of brown, brown, brown or green and brown usually.
