Hiya guys, I picked up a green lash goniopora yesterday, but today I have noticed these black hair like things at the bottom near the frag plug, is this a pest? I dipped and acclimated the coral properly. (The Goni is still closed because it’s first thing in the morning)

Hey guys, I’m quite new to corals in general and was given these frags by a friend, they’ve been fine for the first 2-3 weeks. However, I have just noticed these long threads about half an inch with a white ball on the end of them. I have tried to take some photos, I hope they are clear enough...

Sorry for the potato quality pic but these guys are pretty small. Most are the size of a large grain of sand and completely white. I have a standard 55 that’s been up since 12/20/20. I’ll find around 30-40 on the front glass. Scrape em off and a day or two later they’re back. Thanks in advance!

I’ve been seeing these all over my tank at night and there are quite a bit

Hello - I have had my 1500 Cade setup since December and to be honest, I am struggling. I have had some livestock die for no reason, but for the most part, all of my fish are thriving. My corals are touch and go - some of the harder ones to keep are growing strong and some of the easier ones...

hi y’all, quick question.. in the attached video there’s a coral that’s clearly not happy and on its way out, but there’s a weird ‘wing’ looking thing coming out of it, literally reminds us of ‘fly wings’.. could this be a type of pest and if so, are our other corals at risk? any ideas and...

I recently added a bunch of coral and dipped with coral RX I'm not sure what this is or if its harmful thanks in advance

I got some secondhand corals and I’m trying to clean them up. Are the white tubes anything to worry about? I know the brown tubes are feather worms. Backstory: Yesterday I bought a tank and I didn’t realize it still had fish and corals in it. The tank was nasty and very under maintained. I...

Hey guys I’m new to the saltwater scene and have had this 20 gallon tank for about 4 months so I’m not sure as to what hitchhikers are good and bad but I just seen this guy today and wanted to know on what to do with it.

This is my old dt I haven’t gotten to emptying yet but I noticed this on the glass never seen anything like it. Any idea what this could be ? I used the live rock from this tank hoping it’s not anything bad I just put in my new tank.

I've had my tank for about 1 1/2 years, never had any problems. I have a rock flower anenome, spiny star snails, blue leg hermits, clownfish and an short spines urchin. My pump transformer exploded about a month and a half ago. Killed my emerald crab, shrimp, zoas and I've had problems ever...

Hello! I was looking at my corals today and saw this guy on my candy cane. Tried looking online and I’m not sure if it’s a vermetid snail or a type of sponge. Can anyone offer any clarity and advise of what to do? I’m currently in the process of slowly transferring corals to a new tank and...

Hello Everyone-- I'm hoping I can get some help in identifying and getting rid of an annoying pest in my tank. I think these are dinos but would like to confirm. Been battling this for a year now. First it started out as snot on my rockwork but that's now cleared up after significant effort...

Hey guys, I’ve had these small zoas for a couple of weeks in my new tank. They’ve been dipped with “the dip” by fauna marin and then inserted in the aquarium. After a day, they started thriving and some polyps doubled already in size. However, its been a few days since many polyps haven’t...

I’ve noticed 3 of these in my tank I’ve tried using aiptasia x on this and it didn’t work but this thing has a hard skeleton body. If someone could identify this for me it would be really helpful to know what next steps I have to take to get rid of it

I have asked on 4 different sites and haven’t gotten any answers. Does anyone have any idea what this is? Small and comes out when I feed or at night mostly when I see it.

One last question. I had a couple of things growing on my euphyllia coral stems. Also some fishing line sized worm looking pests on my live rock that I took a polyp off of. Are these pests to be worried about? Thoughts? I really need some input, thanks!

I need your help! What are these tiny worms? I noticed a ton if these smaller worms, there are thousands of them. Looking for an ID on them.

I found this critter today. I am not sure what it is. Good or bad? Should it be killed with fire? Seems like a small orange worm with small white tentacles, or hairs, on one end and pointy on the other end. I hope the pics help. Thank you for your help!

Copepods or something else? Quite a large and dense population. I’ve seen copepods before but never this big. I have some on my glass which are very small.

I have tons of these all over rock and want to know if their a pest, bad, or hurt anything? And if there’s any crab or fish to get rid of them. Setting up a bigger tank and I wanted to know if I should bleach the rock to get rid of them and start over

I am new to the reefing hobby, and I just set up my first Mr. Aqua 12g Long aquarium. After the cycle was finished, I threw in a few test zoas, and they did fine, so when I saw a large frag of an acro labeled "garf bonsai" at an LFS for a good price, I couldn't resist buying it. I didn't have...

Need help with if of coral/pest on side of my Xenia.

I have been noticing that my hammer’s skeleton has been decaying/being eaten for the last few days. I didn’t want to unglue it to inspect it but my emerald crab knocked it over this morning. I picked it up and saw a clear/white curled up worm or something sucking on the skeleton. It was...

Hi everyone. Need some help with an ID on this guy, and if it's a big deal he's their. If so, best action to take? Thanks!
