    Tiny shellfish attached to my turbo snail?

    Hello, My turbo snail flipped itself over this morning, and when I was helping it back upright I noticed it seems to have a very small critter with a shell attached to it: It has a curved shell that looks a bit like a cockle but seems to only have one side, and a little black 'neck' that is...

    Fish Identification.. Yellow with purple lips.

    I’m kicking myself for not asking while I was at the store but.. does anybody know what kind of fish this is? It has bright purple lips, fins, and rings around its eyes. I’ve tried googling the description (in various terms) and haven’t found anything. I can always call the store in the morning...

    Help identifying this coral

    I received this frag as a Christmas gift and I have no idea what it is. I'm hoping someone can help identify it. Sorry for the image quality. If it's too tough too see I can take a picture under the day lights.

    Are these harmless or problematic?

    Hi all, In relation to ticked off corals from time to time, coupled with being able to sleep late and wake up late (vacation for the holidays), I’ve been looking at my tank more at night, i.e. during total darkness. I noticed quite a large population of these, and they seem to be congregating...

    Algae ID

    I woke up this morning and saw him hiding sideways in rocks. It lodges itself but then swims erratically. I need help. Everything else in the tank seems fine and he was eating yesterday but isn’t today.

    What are these weird growths near my Mushroom coral?

    Looks like tiny tubes that each have two tendril things. I think they could be Vermitid snails but none of the pictures online looked quite like them. Another guess is Hydroids but that seems very unlikely. They have only popped up in this certain area next to my Mushroom.

    What kind of coral is this?

    Hi! I'm pretty new to reefing. I recently ordered a mystery coral online because it was such a good price. I had hoped they would say what it was on the receipt that came with the coral so I could research how to care for it, but unfortunately they did not. I was wondering if anyone might be...

    Mushroom ID please

    I’ve had these mushrooms for a while and just realized I don’t know what they are. With having so many I wanted to possibly sell some, but can’t price them correctly without knowing what they are the photos are of them under a white light and with a filter under a blue light

    LFS says this isn’t velvet….

    Hi all! This Saturday, I got a small adult chocolate tang and a tomini tang from my LFS. Tomini has been fine through all of this. I put them in my quarantine tank for observation. They weren’t picking at each other at all, and had actually come from the same holding tank at the store. On...

    What on earth are these?!

    They look like limpets or chitons the size of pinheads, attached to my refugium’s glass pane, but they jitter and have pulsating appendages like isopods. What do you guys think? Below: location of pulsating appendages, circled in red.

    Zoa ID

    Usually I wouldn’t ask but these look kinda bleached out. Anyone have any ideas what the one on the left is? The middle one reminds me of my armor of gods but it’s not the same exactly. It’s got a lot of speckling in the orange on the disk whereas my AOGs are pure orange. But it’s reaching like...

    About that Red Encrusting Algae (not Cyanobacteria)...

    Up until a little over a year ago, I always assumed all the hard, red encrusting algae we find in our marine tanks was just another variant of Coralline algae. Boy was I wrong! I eventually came across this site which made me realize that this "red Coralline" might actually be of the genus...
