critter id

Could you please help me id this snail? It was caught off the turkish coast of the mediterranean sea. It seems to be a scavanger, they all gathered around a dead molly or meat but they don't seem to eat any algae. They are very inactive and somewhat nocturnal i guess. Sometimes they randomly...

Strange object on back glass, anyone have a clue as to what it is?

Had these guys start to takeover my tank anyone know what they are? They are about 2 inches and extend and retract their body to eat and have very small hairs on them like a bristle worm.

Doing a water change in my 12g cube and found these eggs. Anyone know what this is? I have never added any snails. LIVESTOCK -Firefish Goby -2 Percula -Unknown Crab

I have a few critters to ID and I hope none of them are bad. I have supplied a slew of pictures, with no clear meaning or direction. 1. I have a few clear/gray blob things around my tank that are just popping up and I’m not sure what they are. 2. I have a few root-like structures around the...

Hey guys, hoping someone can identify this clear flat worm like creature I found in the back chamber of my Biocube. It hitchhiked from Tampa Bay Saltwater Live rock/sand. It looks like it has a skeleton structure, is extremely sensitive to light, as is super fast moving.

Found this little guy wandering my tank glass this morning when putting up some new frag racks for some coral I had coming in. He/she was not one of our purchased cleanup crew. Did our clean up crew multiply or possibly a stomatella snail? Or is it something else that should probably be tossed...

Got new corals, dipped them properly and i’ve just seen this right now at night. Any ideas what it is and if it’s bad ? looks like a starfish or something similar. quite small and white and pink/ red bands ?

Purchased some live rock from KP aquatics about 3 weeks ago and was trying to spot and catch a possible gorilla crab but I found this instead. I think it is a fire worm but not sure as it could maybe be a bristle worm too. Anyone have any ideas? Sorry for the loud noise in the video it is the...

I was cleaning my glass and noticed an abundance of these small Star like critters on my glass. They’re tiny - like a thin point to a lead pencil. To my eye they look like 4 pointed or Star shaped, but my phone was able to take a pretty detailed photo. Here are two different ones. ‍♂️ curious...

There is something semi transparent under one of my zoanthids, anybody know what it is

No idea what this critter is been trying to ID but can’t find anything. I’m new to the hobby and hoping it’s now bad for my reef… thanks in advance!

Hello, I recently started noticing 2 small white centipede like “bugs” on the glass of my tank. They have antennaes, many “feet” like a centipede, move slowly, and are completely white. The bugs are very small but still bigger than pods. My tank has been fallow for 8 weeks now following a...

Is this a group of small feather dusters on my frog spawn?

I had a friend that is getting a new tank, so had to get rid of a lot of his corals. Some of his zoas have feather dusters, which I’ve heard are healthy for a mature tank. These pink cat eyes are the only corals that have these. They’ve been in my tank for about a week and have now popped up...

I’ve just discovered this weird critter on a rock. It was latched onto it super tight so I unfortunately crushed it to remove it off said rock. Looked like one of those centipedes that roll up into a ball on land but in the water. Any ideas ??

Hi! Could someone please help me identify what this is? It’s in my sisters tank and I’m stumped! TIA

Hello! I run a 5 gallon PICO tank that until yesterday had no fish. I also feed phyto daily, so there has always been an abundance of wee beasties that have fascinated me. Most I've been able to identify (copepods, amphipods, munnid isopods, spinoid worms, spirorbid worms). However, there have...

Hi all, can anyone help me identify this white mass in my GSP? I noticed two of the masses have holes in them.

So, I noticed these kinds of white bulbs popping up a bit back and I took a closer look at it this evening and noticed it's starting to develop neon green. I like to let my tank go all natural and really thought nothing of it when it first started appearing. Now, I'm curious about what it is or...

Hey guys! My friend found this weird critter in their tank and we have no idea what to ID it as. Looks like some type of worm. Unfortunately there’s no pics of it in the water but I’ll attach a couple of pictures from outside of the tank. The spikes along it move almost like an urchins spikes.

I noticed in on my rocks. I have no idea what it is. I have 2 clowns, cerith snails, nassarius snails, 2 scarlet hermits, 2 blue dwarf hermits, and an emerald crab.
