Ah ok thanksIf it’s not all of them and just a few of them, it’s probably its sweeper tentacles. It uses those to sting other corals.
Thanks for the info!They tend to open more when they get full spectrum light and close when the lights go more blue and dim. But if its not receiving enough light they tend to stretch more as well.
I noticed that the polyps have gotten longer and are spread out more.I don’t see that in your pics but the long, stringy ones would be sweeper tentacles. That a good thing as they are feeding and protecting the colony. I’d only worry if everything seems to be going stringy which is not normal. Not that sweepers sting other corals, protective move, so just be careful what you put next to it. Other hammers and frogspawn are fine!

Is this what you meant by everything going stringy?7

Let’s see if this loads for you.

Going stringy would be tentacles that are noticeably thinner and longer than most of the colony.
I think your polyps and their tentacles look good. Let me see if I can show you what I mean with a frogspawn where it’s much more obvious than hammers! I’ll post a pic if I have one in my library or I’ll take one and post.

See the long, flowing tentacles? Those are sweepers. Hammer ones won’t be as thin but they will be noticeably different from all the rest.
