pest hitchhiker

I noticed this little guy this morning when my lights first came on. Is this a baby turbo snail or something I should be worried about. I have 2 turbos in my tank. Thanks for your help. I haven't added new coral for about 6 months.

Anyone know what these white objects are on the base of my torch coral? They extend perpendicular from the skeleton of the coral

Hi Everyone! I wanted to share my recent success with using hydrogen peroxide to kill Aptasia and Manjos in my reef tank. I couldn't find a whole lot of details about how to do it so here is my success story. A warning to everyone concentrated hydrogen peroxide. This stuff is dangerous it can...

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

Hello my name is Kasey and I am new to the saltwater hobby. I have been in the freshwater hobby for 10 years and have finally converted to the dark side . I currently have a new tank set up (2 months running) with live rock, a bicolour blenny and a PJ cardinal. When looking at my tank I notices...

I have these “worms” in a few spots in my 55 gal reef not sure what they are or if they are a pest or not.

Hey everyone, I picked up a warpaint scoly last weekend at Reefapalooza Orlando and only noticed afterward that it has a chunk of flesh missing, which seems to be worsening each day. I already gave it a 6-minute dip in Revive when I brought it home. I have a couple of questions: 1...

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...

ID ?? Thank you in advance!

Hi Guys lately i have seen in my salt water aquarium in the return tower this small dots i don’t know if they are eggs or small pests do i need them or do i scrape them off. The fish don’t seem to be interested. Sorry for the quality of the pictures it’s impossible to zoom close enough for the...

Checking on My year old 75g as per normal. Looking at the glass and i see this thing on my glass. I’ve been pretty good with not having nasty hitchhikers in my tank. At first i thought it was some sort of flatworm. However, when i went in to remove it the exterior was hard and when i pulled it...

Hey all! Relatively new to the hobby with less than a year of experience. Noticed my lepto wasn’t looking too hot and shortly after, I noticed these guys hanging out on the underside of the frag. My searches through the forums lead me to believe they’re hydroids, but I was hoping someone with a...

Looks like a shrimp of some sort. It’s it coral safe is the question. Don’t know how it got in the tank but it’s there. Found in the refugium Photos of video doesn’t play. Main question/issue why happens if it populate the tank

I’m looking for a strictly academic/ best guess. Is the imadcloprid or is the cyfluthrin in Bayer ….( since they are 2 very unrelated insecticides) responsible for eliminating any unwanted guests as a Coral dip/treatment. Also, any anecdotal information on what exactly your trying to kill as...

These guys are all over my tank. I have looked everywhere and asked many people, and no one seems to know what these are. They seem more active at night and when trying to touch the tentacle it retracts. I know it is definitely not a bristle worm or vermitid. And I do not think these things...

Pest id please

I was cleaning my coral with hydrogen peroxide solution and 2 worms dropped from the holes. I don't know if it is a bristle worm which became fat due to hydrogen peroxide or it is my nightmare: a fireworm. If these are fireworms are there any easy hacks to get rid of them.

These little white-gray friends are spreading rapidly through the rocks. They dont look like they move (aka dont look like barnacles) and are a bit see-through. Some of the corals that are in contact with these are a bit angry. Anyone know what it is and how to get rid of it?

About a month ago I noticed white specs appearing on my ulva and chaeto in my sump. They’ve now grown to be quite large. Initially I thought they were trochus snail offspring, but I am more concerned now that they might be a pest. They are eating holes through the ulva and have almost devoured...

I have these little dudes in quarantine and wasn’t able to pop them off their plugs. These survived their dips and I’d like to know what hitchhikers I’m dealing with as my display tank has none! On the acan hitchhiker one is part of their skeleton. On my encruster, hitchhiker 2 are on bottom...

Frogspawn not opening

What are they and how to get rid of them? What product to use safe for fish and coral. Thanks

i have heard that blue sapphire damselfish (the peaceful ones) eat flatworms, and i was wondering if they (or any closely related species) have been known to eat bristle worms? obviously im not expecting this random 6 dollar fish to have the appetite of a melenarus wrasse, but i do just want to...

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!

Hi All, I am new to reef keeping and I thought it would be fun to share my introduction (horror) story to the hobby. I started out with a 10g tank that had an arag-alive substrate bottom. I then bought 2 chunks of live rock and let the tank go for a few weeks while monitoring the water...
