So for some reason this is the first time I’ve truly looked at my tank with a flashlight in complete darkness. Well I turn the flashlight on and these massive spaghetti like tentacles (6-8+” retract back into the rock. There was two origins of these tentacles and couldn’t see whatever creature it was. I couldn’t get a good pic or vid because they haven’t fully extended again. Second I have these things... pic below if someone can id. Those little spaghetti things have me more worried. Super creepy, I’ve never read anything like it one here

Guess I should’ve done research first before freaking out. I guess I was spot on with spaghetti like tentacles, I think it’s a spaghetti worm lol. They say the tentacles can get up to one meter and just catch detritus so I’m assuming it’s harmless to all other coral and inverts and fish? And those small things are chitons? If any one can just confirm that they’re good and I’m right just to make me feel better lol.

Spaghetti worms are good if that’s what they are, great cuc members. Cant tell what the pic is, maybe chitons? Too blurry
I’m 99% sure they’re spaghetti worms after looking at pics online. Those other things I can’t really tell. Here’s a couple other pics but they’re still kinda blurry idk if they’ll help much

this is a tunicate possibly genus Botryllus

yeah the terebellid worms are pretty fascinating and very beneficial
