pest

Just moved a rock with some zoas from my older tank recently, into my newer tank where it would be seen more. But anyway noticed today some the heads not opening all the way and noticed a whitish mound at the base, not sure if it's a type of sponge or fungus?? Thank you

I bought a small zoa frag about a week ago that had some “string” coming off of both the stalk and the plug. I pulled off what I could, but, after returning from a week long vacation, they’re all back and there’s more than before! I’ve tried looking this up but can’t seem to find an answer. The...

I bought my first ever coral about 4 months ago, a small 2 head Torch and a fungia plate coral, I dipped them both and got a small flatworm off the torch luckily. A few days into owning the torch and watching it get used to the water and extend, I noticed a little section of bristly exoskeleton...

I got some nassarius snails from a seller ive bought nassariusses from but they were much darker in color hoping its a different species. They are much more active in the tank than my all white ones. They do move quickly on the sand but i have never seen a whelk so im not sure how fast they are...

We all like to treat our Coral with dip and maybe some of us don't do it or never have at all. I would like to know, what is the coolest hitchhiker that has made their way into your tank? Through buying Coral, live rock or live sand or anything. It would be interesting to find out if anyone has...

Need some help identifying this thing. I recently have had a issue the past month with something eating my pally zoas. Could this be it??!?

Doesn’t look like a normal bristle worm

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)

Hi there, apologies as it can’t get a picture as it’s so small. I picked up a large GSP colony attached to some live rock. That is doing well and I am happy with it! However, I looked underneath the chunk with my phone light as I saw something scuttling upside down under the rock, It is about...

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...

What would you do in this situation? I'm out of ideas, and at the end of my rope..... My 210G tank is COVERED in aiptasia.... i mean literally Thousands of them. and some of them are LARGE, like larger than my hammer corals polyps, and in every corner, on almost every coral, and they seem to be...

Noticed these in my tank today, what are they, are they dangerous should I remove them?

LPS a ting funny last few days, pulled sample off an elegance, 400x showed this guy. Doesnt resemble a pod? What am I looking at?

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.

So I’m doing some maintenance today and I was moving my chalice when I noticed this growth on it. I’ve seen these guys on a rock I have in my sump that has fan worms on it so I figured they were baby worms until I saw them on the skeleton of my chalice. One was heavily infested while the others...

Hello, Would really appreciate some help identifying this hitchhiker on my bird nest. It’s got two antennas which seem to be coming out of a polyp and coral has turned dark brown around it. Would a Coral dip help? Appreciate your guys help!

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...

I’ve got a 37 gallon live rock and live sand only things in the tank as of now is a feather duster, astraea snails, nassarius snails, and a tuxedo urchin. I recently introduced a frag of zoa but I did dip it and inspected thoroughly before placing in tank. I noticed today a little critter...

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...

Hi guys I found this snail under my coral drag of torch and really worried if this is a sundial snail or not

Hello! I run a 20 gallon tank with a few easy keeper corals. I’ve had the tank for close to a year now and last night I noticed a crab hiding between the rock work in my aquarium. Based on what I’ve read it’s rare for these guys to be beneficial and was wondering if anyone had advice for finding...

I was topping off my tank and noticed these little white specs crawling all over the glass. Not sure if they are good or bad, please help identify and share treatment plans if needed. Would be much appreciated thank you!

Hi guys, Could someone identify this bug on my zoa? Friend or foe?

Hello, Can someone please identify what this is on my Ricordea Florida? It has been opening up so large that I normally wouldn't be able to see it. It's normally real happy and covers a good bit larger area than the plug. It's closed up because I was picking up skin from my cleaner shrimp that...

I’ve recently noticed pest in my tank and my corals have became unhappy, i also see bubbles on the sandbed and a lot of algae on the glass, paramaters are okay, although cant tell for phosphate or ph, its been an ongoing thing with the pest so i wanna do a tank restart. I wanted to get some...
