    ID assistance appreciated! Tube worm?

    Was checking my tank under red light last night and noticed some kind of tube worm (?) on one of my softies. It looked a bit like a feather duster at first, but zooming in on my camera I noticed it has a forked appearance. I just want to know if it is something nasty - has already been through...

    Hitchhiker coral or pest (or both)?

    I'm looking for an ID on these little purple buds that appeared on my zoa frag. They survived a coral dip when I first got them, so I wasn't too concerned about them until I found more elsewhere in the tank. I'm thinking they're some sort of clove polyp as I think they have multiple arms, but...

    Are they corals?

    Hey, i'm so fascinated by hitchhikers than i could buy live rocks everyday to get new ones! But here are the one i still have doubt on what it is. I think they may be corals for 1 (the thing with big filaments) & 2, they are open when lights are on but maybe a pest anemon for 3? Thank you for...

    What is this? Clove polyps or some pest?

    Hello, I obtained a zoanthid frag which included a small piece of rock the zoanthid was on. I dipped and quarantined the coral and put it in my my main tank two week later after it looked free and good. Now a week later I notice these are popping there heads out of the rock to get light but...

    White worms on zoanthid. Filter feeders possibly? Please help.

    Hey I am trying to figure out what exactly these are. They covered the base of this zoa (my personal favorite of the tank) after a cyano outbreak. After multiple months of work and a uv sterilizer that is under control but this seems to be left behind. Could this just be like a ditritus worm or...

    Growing sedintary hitchhiker bothering Zoanthid

    I have an interesting hitchhiker I would like to identify. It has been growing here along side this zoanthid and sponge. Originally when I placed the frag I had dipped, brushed and thought it free of all but the sponge which I decided not to bother removing. However a few months later noticed a...

    I don’t think it’s aiptasia…

    From what I’ve seen from Google images, I don’t think this is aiptasia, but I could be wrong. If not, any idea on what this is? Seems to be a very thin tube protruding from rock with short red/orange tentacles coming out of end of tube. 8 month old tank with live rock. Hopefully this zoomed in...

    Red/orange bugs at nights

    I shined my flashlight on my tank at night and seen these weird worms that burrow in sand when I shine the light on them. In the video one was swimming... well wiggling and at the end one was burrowed. Does anyone know if these things are dangerous?

    What is this critter?

    https://youtube.com/shorts/fIXCgW_Su4o?feature=share What is this creepy crawly critter? Found him near a small piece of rock I recently removed from the reef tank for my Algae ID post. Hard to tell from the paper towel, but he had a white sac-like thing on his behind. I had given the rock a...

    What are these? Cannot figure it out. Hitchhiker ID

    Small roundish soft thing sitting on a “nest” of tentacles similar to that of a nudibranch or bubble tip anemone, however they do not move freely and are stationed where they are, have not moved an inch in almost a week. I think Nudibranch is ruled out When I touch them they react and “extend”...
