pests

Anybody have any input on removing or reducing this yellow sponge? Surprisingly very little info on it on the internet. I read someone say that it can take the calcium and carbonate from rock and cause it dissolve. Well, I have it on my dragon soul torch colony stalks and one day one stalk...

Hi All, So I moved a coral today and noticed the below! There were a few 'shells' I had seen a month ago, but now they seem to be overtaking! Any suggestions for complete removal??? Thanks all!

I’ve been searching the web on this and see a lot of info on the do or don’t dip. I have a newish tank build that I’ve been careful to not introduce especially - bristleworms, spinonid, vermetids, spaghetti worms and detritus worms to because my first tank is filled with that and I hate it. My...

So I just bought a mushroom from my LFS, and I did my first reef dip. Before my second reef dip, I cut off the frag plug and saw that there were flatworms crawling off and out of the frag plug (2-3). There were two frag plugs stacked on top of each other and some of the worms came from in...

So to make a long story short a couple of my digis were not doing too good. I didn't think much of it and I ended giving them to a fellow reefer. These digi have not done good for me for like the past month or 2. Everything else is fine. He got back and said I had black bugs?? So I immediately...

I have a fairly new mixed reef with only 3 fish and some CUC, my combtooth blenny has been flashing for about a week, previously he was swimming around all over the tank and now won't eat and is always hiding. He was in observation for about week before adding to the display tank, did a FW dip...

For starters here is the link to their website: https://killercorals.com/ I was looking for some cool zoas to add to my tank and this company has some that I like and I was wondering if anyone has ever ordered from them before? Since I prefereably want to order from a reputable source as I...

Hope everyone is doing well , just wanted to get your opinions. I took a very long break from the hobby and recently got back in about a year ago. since then , I have spent nearly 5 figures with a large/popular company that is supposedly quarantining their corals in an attempt to be pest free...

My favorite torch started to retract a bit recently, and after dark I shined a light on it to see these little critters. Gave it a good dip and moving it to the bottom of my sandbed to recover until I get it into a clean tank I'm starting. Does anyone know what these are? I don't have acropora...

Welcome your thoughts/advice. I picked up a cleaner shrimp and psammacora frag at my LFS last weekend and put them in quarantine in a small (betta) tank in an abundance of caution: my nano has been running pest free for over two years and I'd like to keep it that way. I am now seeing what I am...

So i noticed this weird tenticle pop out of one of my rocks. Kinda looks like a bristke worm but its huge. This is the best video I could get.

I have been in the hobby for five years. I have been able to achieve good growth and color from both soft and hard corals (lps & sps). I was feeling pretty good about myself. Maybe a little cocky. I have never had a significant aquarium pest. I had aptasia and bristle worms. I researched...

This is literally just to sate my curiosity because I like asking questions - I don't have aiptasia nor majano in my tank so I don't need help eradicating it. Anyway, I have a few pest 'nem questions! I know I could just google these, but I would rather ask people who are actually passionate...

I have removed this in the past but it keeps consistently growing back, wondering if it could be identified and the best way for me to remove it permanently. (white slimey things in the image)

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...

I used to be pretty active on here, years ago. Excited to see if some of the OG's are still around. Firstly, thank you for your help in figuring this out! My Tank is a 29 Gal JBJ Cube with Eshopps Nano Cube Refugium Sump Roughly 33-35 gallons overall. Parameters are pretty stable (I will...

Hello all, I have a 125 gallon LPS dominant barebottom reef tank. Recently I've started noticing some red flatworms (planaria) on my live rock and want to do something to combat them. They haven't been noticably affecting my corals, but I'm sure it would be better if I get rid of them. I've been...

Please help me iD this guy. One of my hammers is struggling and when I decided to cut one of the heads this guy felt from the coral. Thank you in advance.

Hi folks. I need help identifying this pests. I’ve seen them before on my DT on a few rocks, but now they are all over the place and specially on all surfaces of my sump. Please help me confirm this is aptasia or something else? Thanks

Noticed some of my acro frags have head really bad polpy extension lately and decided to dip some of them in coral Rx. I was trying to zoom in on this really small black dots, can anyone verify it is a black bug or do i need better zoom? Hard for me to tell if its just debris or something worse...

So I asked this when I first started before I knew what Aiptasia was. I have since observed Aiptasia in every single LFS retail location I have visited. They all have it in their systems. It's not a lot. It's not covering everything. But it's present. I understand and agree with the idea that...

I have quite a few of these over my glass bottom and in my rockwork. They are probably up to 1/4" in size and are hard to scrape off of the glass. Everything in my tank seems to be doing well, just not sure what they are and if I should do anything to remove them.

So our frag tank is just filled with detritus, algae, hydroids etc. We failed to dip the original frags which was the downfall, new ones will be dipped in reef primer and lugols, but how can we clear the tank of all of this? It looks disgusting struggling with phosphates, calcium and alk...

Hi i know it’s a very odd question to be wanting a pest anemone but I’m starting a pico tank in a couple months and wanted to add those for it as a species only tank. I got the idea from Reef Dork on YouTube.

I'm 5 months in, and my little aquarium is happier than ever, with tons of biodiversity. I've got spaghetti worms, amphipods, copepods, bristle worms, and stomatellas.... And Aiptasia. The one thorn in my side lately. dang aiptasia! I've been using Aiptasia F for some time to deal with Aiptasia...
