Hello please help me identify this on my GSP coral. It doesn’t seem to bother my GSP too much as it still fully opens up during the day. But it’s white and semi transparent. Looks to be firm and doesn’t move with the current. Web like appearance.

I just cleaned a bunch of algae out of my sump and found these critters that look like tiny smooth (no hair or bristles that I can see) caterpillars. I’ve never seen these. In the photos they look flat, but they aren’t. They are nice and chunky. Any help on an ID is appreciated!

Coral Only tank, no fish/inverts. Any idea what this little tentacle is? I recorded one of them but I see 2 short ones and 1 slightly longer one. If a pest, any advice on how to remove it?

I got a good deal on some live rock from a gentleman on Facebook probably about 50 lb for about 80 bucks. The rock looks good supposedly he was storing it in a container with a powerhead and heater I don't know if I believe the heater part but besides that The Rock is definitely covered in...

So I have a large population of asterina stars. I appreciate some people have no problem with them and actually value them as part of their cleanup crew. I’ve noticed them eating my Zoa’s and I’ve been doing some manual removal but never thought they would pose a risk to fish. Checked the tank...

I’ve always noticed small fine red hair sticking out of my sand every now and then , especially when lights out . But today I was doing some sand bed vacuuming and notice something move in the sand bed and i ended up sucking it up. After I was done with the task, I went back and looked in the...

This guy just showed up in my 6 month old nano. Any ideas? It looks like a work with tons of stringy tentacles.

I just dipped some new frags and found this Anemone in with them. It doesn't look like any Aiptasia I have ever seen, I'm unfortunately really good at getting them in my tank... But this is definitely some kind of Anemone. Thanks for the help in advance! lol.

Hi guys, Recently started my first saltwater tank, and having difficulty identifying what pest this is. I assumed aptasia but looks different from the aptasia pictures I see online, it’s thinner and has small balls/heads at the end of each little thread… I introduced some Berghia nudibranches...

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!

Hi Reefers, So I bought this colt coral few weeks ago, and I noticed that there is somewhat looking thingy next to it, so I though oh maybe that’s his kid or something (don’t judge me please ) But at night I realize it doesn’t scrunch in like the colt. Does anyone know what is that? should I...

What is this thick white spider web like stuff on the live rock? What can I do to rid it?

Hello All! I have attempted to take a few pictures of some sort of Algae? That I have growing in my sand. It looks red under blue reef light. It has threads up to 2ish inches long all comming from a central point. The threads are very fine and blow around constantly. Does anyone know what this...

Hello,I found these hitchhikers that came out of my live rock. The first one is some sort of strings that are in between two rocks. The second one is one string coming out of this tube on a rock. And the third one is a weird slug looking thing that was on the glass. Any ideas as to what these...

Hi So just got some montipora setosa, it's been doing fine for a week. Today the polyps where mostly closed, and can't remember seeing this white on it before. It's very very small, is it a nudi baby?

Hello, I just found a mantis shrimp in my new tank that came from live ocean rock. With what I’m seeing online I’m not sure if this is a good thing. It’s pretty small; about the same size as a large amano shrimp. It’s also constantly making a clicking noise; I’m not sure if it’s just punching...

Hello everyone, i noticed this stuff growing on the flesh of my Trachyphyllia. Is this a sponge? Because if you zoom in, it kinda looks stringy, like a ball of nematodes or something. Thank you all in advance

Hi guys, I have this SPS frag - acropora granulosa. I dip all my corals in reef primer before putting in my tank. I saw some small white dots moving about on it today, prob more notice than on other frags I have here as it's a lot darker. Polyp extension was okay, not amazing. Once I saw this...

Hello! Rescued a sizeable pectinia that had a couple pests on it. It had a large vermitid that I glued over, a majano which I injected with lemon juice and covered with CA glue. There is a red sponge which I hope lives! BUT...What's in the picture? It looks completely different from the other...

What are these Little Critters that are appearing more and more in my tank? Are they a pest or good ? If a pest what if best way to remove them

Hello everyone So in the beginning of February I broke down my 75 gallon display tank bleached all the live rock except for one that had a mushroom coral attached to it. In preparation for my 125 gallon upgrade. I removed some substrate along with that rock to house long tentacle, my bubble tip...

Hey all, I’ve recently noticed these tiny brownish worm like creatures all over my rock. If you look closely at the picture, there’s these white strings as well that seem to be trying to grab food off the sand. Any idea what these are and how to get rid of them??
