critter id needed

Any help with an id for this critter that has decimated half of my papaya clove coral

Hi, I just woke up and while doing my morning tank inspection, I found these little critters floating/swimming in the corner of the tank. Can you please help me ID what are they? Thanks

Found this red critter on my back wall amy idea what it is? The picture makes it look more brown sorry. By the way it doesn't move.

Found a cool looking critter on my Tampa Bay live rock. About an inch and a half long. Not sure what it is. Good or bad? Does anyone know what it is?

I saw this long black filament coming out of my snail earlier today and can’t seem to find what it is… It’s the size of a long chaeto filament but black and I only have some in the sump, which would be interesting if it got all the way into the dt and in the snail… also the colour doesn’t match...

Hello everyone, I have these very small white things on my glass that are moving around every few seconds. My clownfish seem to be eating some of them. I can't get any clear pictures but I do notice that they have really small antennas on their head.

Anyone know what these tiny bug/shrimp looking things are? They are all over this rock and under the coral. Are they good for the tank or are they about to kill everything in sight? Thank you!

I have heard everything from pistol shrimp babies to bad isopods. To good film algea eating isopods. Can someone help me ID these please. If you zoom in it looks like mandibles on the big front end. I disturbed the back chamber of my AIO and these are now all over my display. Thanks!

I’ve been noticing these here and there. Didn’t realize they are everywhere at night till recently prob 50+. Move pretty quick for their small size. Any thoughts would be much appreciated!

Good morning all! Rearranging a Zoa colony found this guy. Is it around 2” long. Quite cute the wanker. Is it friend or foe?

I found this on my tank today. Anyone happen to know what it is?

It came on my gsp and jumped off while I was dipping. Should I put it in my display?

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...

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...

Found this worm looking thing on the glass? Looks like it survived a dip at some point, very dead now but thinking where is the other 100? Thanks!

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...

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...

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...

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 have this squishy translucent sponge like thing growing on the side of this coral. On the top, a bit to the right of center, is a small tube with two small translucent white tentacles coming out of it. You can only see one tentacle in the photo. The large cut on the sponge thing is from me...

Let me know if you need better photos. These keep multiplying and I’m wondering what the heck they are. They are little white pills that have been very very slowly move and quickly multiplying.

New here.. tank is about 7 months, have some torches, fireworks, hammers, and xenia. Tank is in recovery stage from velvet that wiped out all fish but 2 which are in copper QT. Found some aiptasia on larger firework frag and took it out to grab it off and super glue. These tiny quick, shrimp...

Hey guys just a quick question. Monthly, I add @AlgaeBarn ecopods. A couple of months ago I used one shipment of the Galaxy pod mix. Today while feeding my corals, I noticed in my chaeto overgrowth box these little (1/8 inch?) critters. I've looked around at some pictures but I can't seem to...

So I noticed yesterday that my galaxia coral had what looked like bubble algae on it so I took out of tank and got it off and then noticed this creature that looks like a Rolly Polly gliding under the plug . It has a hard grey shell that has some dark markings on the front and back of shell. It...
