What are those!?!?

I have a reefer 250 G2+ Max that has been going for about 3 months, have some minor hair algae in the display I’ve been working on. I was getting ready to do my weekly maintenance and noticed some stuff living in the crushed coral in my sump. One of them appears to be possibly a feather duster, one may be a pineapple sponge (but I’m not sure and have no familiarity with them) and one is translucent spaghetti looking things that are in the crushed coral. I have moved some of it and it doesn’t react to being moved or touched.

The one is definitely a pineapple sponge, the others are probably some other form of sponge.

Anything to be concerned about? I’ve never had sponges appear in my reef tank before.

If your tank is only 3 months old it's still getting into the swing of things (assuming this is your first saltwater tank, apologies if it isn't)
They are a typical sign of a healthy tank. Shouldn't harm anything. If they grow too big you can remove them as needed. The pineapple ones should disappear on their own.

Perfect, I figured they were probably ok. I had a reef tank in the past (17 years ago). I’m just getting back into the hobby so I’m a little rusty.
