    Jellyfish taking over my NUVO 10

They spawn out of nowhere and now i might have a hundred or two in a cup of plastic with holes i made for them inside the tank. I currently feed them rotifers and planctonic copepods but i dont really see them...

    What kind of starfish is this?

    It had to be hidden for a few months. I don’t want it if it’s going to eat my coral. Sorry for the fish in the picture, he would not stop begging for food in front of the camera lol.

    ?Worm? ID

    Hi all needing some help IDing this worm/cucumber/tunicate looking thing that came out of ocean aquacultured live rock. The larger side slowly moves and changes length (more inflated/less inflated). I haven’t seen any sort of mouth or feathers etc. Any ideas? Thanks JF

    Spanish shawl nudibranch?

    Found this little guy roaming on my zoa rock just now. Thought it was a bristle worm at first but after it moved into the light, it appeared to be a nudibranch of sorts. Can anyone confirm?

    Hitchhiker on live rock, ID if possible

    Purchased some live rock from a tank breakdown. Was going to boil it but had a spare tank and thought why not, let's see what happens. Day 1 this guy sprouts. Any idea what it may be? 34 years off and on saltwater aquariums. Planning on using in a coral only tank.

    A few hitchhikers I would like some Id confirmation and advice on

    Hello everyone! I'm relatively new having a fish tank, let a along a reef tank! I started my tank around a year ago, but have only recently started to populate it with more corals and fish. I've read through some of the different guides on hitchhikers and those were all super useful! Thanks to...

    Weird Cartilage looking tubes in tank

    Hi, my tank is around 2 years old, and these weird things have been growing slowly for a while and I never thought anything of it. Today I decided to remove them and they almost felt and looked like tendon when split. Would love to know what they are, thanks !

    Tiny Clam ID

    Hello, I just received a cleanup crew shipment and in one of the bags with a whole mess of dwarf ceriths there was what looks to be an extremely small clam. It's no bigger than a centimeter and I'm wondering if anyone knows if it will get larger or remain small. I placed it in my sand bed...

    Tiny pink crab

    Finding hitchhikers (benign ones especially) is actually one of my favorite things about reef-keeping! And today I noticed a new friend in my 1.5 gallon that I most definitely did not add. It’s a beautiful little crab, but not particularly active— I’ve never actually seen it move, just sort of...

    Feather duster or pest?

    Hello all! During a sand bed cleaning I just bumped my trachyphyllia that I've had for about 2 months. It looks like there is a feather duster worm hitchhiking on the bottom. Is this a feather duster worm and it's harmless? Or is it something else? Should I remove it? If so, how? Thanks in advance!

    Couple of weird things...

    I was culling out some vermetids snails today when I noticed that there were some weird "bubbles" hanging off my zoas and some of the stems of the colony had turned yellow. I poked at the bubbles a little but nothing happened. Obviously I had irritated the colony so they were mostly closed .the...

    Good or bad snail?

    Hitchhiker on Fighting Conch

    Received a Fighting Conch from an online delivery today. I noticed what looks like a snail of some sort stuck to it. Any ideas? Can or should this be removed? Seems healthy and has been out and eating since it hit the sand. Thank you for any advice.

    Worm identification

    I am in the process of moving my tank to a larger one. While removing the rock and sand I caught 3 large worms. I can’t tell if they are large bristle worms or possibly Oenone fulgida? They don’t have the large tentacles of a eucilide. It has a black mouth/head which doesn’t match my other...

    Coral? Barnacle? Cucumber?

    And here I thought I was at least decently familiar with most hitchhikers out there. I haven't the slightest clue what this could be. Weirdest part is that it wasn't there just a few hours ago. Bare rock this morning.

    Possible Spaghetti worm?

    Hello! This isn’t exactly new I saw the hair like feelers a while ago but now for some reason it has really moved around the tank a lot. I’m pretty positive it’s a Spaghetti worm but I want any other opinions as I’m not too versed in hitchhikers. Thank you in advance!
