pest control

Are these copepods/ amphipod or something else bad?

My gsp has not been opening fully for the last 2-3 weeks I just noticed this clearish looking thing growing near the bottom I thought it was aptasia at first but it doesnt really look like it. Could anybody identify what it is? and is this the reason my gsp has been closed? I attached a couple...

Aquacultured coral is coral that’s grown in controlled, aquarium-style environments instead of being taken from the ocean. These systems use stable lighting, flow, and water conditions, so the corals grow up already used to the type of environment we keep in our home tanks. Because of that...

Hi All, I’ve had quite the journey with Aiptasia & I decided to start this thread as a thread of support, for people currently overwhelmed by this demonic entity…. I am currently in the process of setting up a new tank - due to Aiptasia being in the old one. Instead of seeding my new tank...

What are your experiences with these wrasses? Any opinions on which is better? Which is more peaceful? Which one has a better personality? I have found that pink streak tend to be less available and more rare. Is there any place that sell quarantined pink streak wrasse? Which wrasse is better...

I posted this previously with some crappy photos. I finally got my phone to focus. I will be editing the old one also but I hope this gets some traction. Have had this white fuzz on my rocks and i have a feeling it killed off my hammers and it's moved it's way to my zoas. In fact the only hammer...

Hello, Are these ball Anenomes? They are all over my reef tank and seem to be bothering my corals and stay open all day. They also attacked a baby hermit, and seem to be really aggressive. Also, any natural predators? (For a 40G tank) Or other alternatives to remove? Thanks in advance!

Hello R2R, I have a lightly used AquaUV Classic 15W with 2" to 1" unions. This UV is guaranteed to work and was tested on a Reefer 250v3 with custom return pipe and Apex COR15, getting 220gph at the 35% range. This is an ideal UV for anyone that wants to control or manage pests while also being...

There are tiny worm looking things on my clam, they are hard to the touch, what are they? I read somewhere they could be vermitid snails or tunicates but I’m not sure, and should I remove them?

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

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...

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...

Hello all, I have a new tank with no inhabitants. I had some red ogo I rinsed well and kept in some fresh salt water for a week or two before adding to the tank. I didn't see anything on it and thought I'd be fine. Nope. I now have literally thousands of these crawling hydroids. They're the star...

Hello guys, I have this struggling hammer . I’ve done entire due diligence ( gradually increasing magnesium, adjusting flow… ) but it’s still doing poorly and it seems a pest problem. On it there is a feather duster, some sponge like things and I noticed today one very tiny worm ( baby brittle...

I got this almost new reef delete when buying a used setup, supposed to destroy pest DNA so they will not be able to reproduce and eventually get eliminated. I dont think I would use it. New ones sell for $350+; selling it for $280 with shipping included.

Hello Everyone This is a thread to hopefully finally figure out what these strange worms are. These have appeared in many threads in the past several years but so far we have no true ID , as it seems they are becoming more prevalent in our systems , I thought I would put together one final...

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.

Hey there I have a 35 dsa lagoon tank and in the recent weeks I’ve had these random things pop up not sure what they are. I asked other forums and no one knew any help would be appreciated thank you !

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?

Hi all! I have seen baby aiptasia pop up in my tank very infrequently, I usually spot about 1-2 a week (if any at all) and I’m a person with really good eyesight. These baby aiptasia have always been on a rock or frag that I was able to pull out and treat out of water, however in this case, I...

So I have had this coral for over a year, and this frag in a branch from its original colony. I was doing ok for 2~3 months, and suddenly it stops growing and I can observe zero polyp extension even at night time. It does keep encrusting on the rock as of now, and start to show some fluorescent...

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

I’m looking for some recommendations as to how to rid my tank of these pests. After being told to let them run their course I’ve had no luck in them disappearing. They now cause my zooanthids to constantly shut. Have read that it’s due to their stinging nature. Looking for an invertebrate or a...

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...
