pest

I kept observing everyday and I didnt see any sign of it, but after a short travel I see packs of flat worms on the polyps of my goniopora, I took a video of it, but they are literally all of it. I am assuming these are the harmful flat warms and should be dealt with? If I am correct what would...

After being visibly pest free the past year I believe I’ve just spotted a fireworm. Can anyone brighten the night and say it’s a bristleworm?! If it is a fireworm, I plan on swapping out my scape to all new dry Marco rock - didn’t want to change the sand though. Any suggestions?

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...

Hey guys I just got a new hammer and Duncan from my lfs. After I dipped them these little worms came off the hammer. Are these the flatworms that eat euphyllia? What’s the next move on this?

Noticed this patch of zoas tonight after a herm ran them over. Seems to be quite a few only on this portion of the rock growing all around the base and stem of the zoas. Any ID help would be much appreciated! Thanks in advance!!

Saw this on my damsel this morning… impossible to catch the fish so far ☹️. Can anyone tell me what type of pest it is and if it’s going to come off on its own?

I just got home from a trip and noticed some small black dots on a little frag I have. Does anyone recognize these? My first thought is a flatworm or something but I can hardly see them. I took it out and dipped it as soon as I saw it, but I'm considering if I should dip the rest of my frags. I...

I’ve just bought a pyramid algae snail (tectus snail) from my LFS, i put it in my tank and i’ve come to realize it has this weird looking thing on it shell. Whatever it is seems to retreat quickly back into a hole in the shell when i move the snail when it feels endangered. can anyone help me...

Hi guys. My tank has been running about 3-4 years now. I haven’t seen these worms at all really. In the past few months their population has increased rapidly. Are they bad? I’ve had a few polyps die off on my LPS, but that could be from something else. Are these things bad? What are they?

Hello Everyone, So I am currently concerned but not too concerned about these weird pests that I have found living on my Zoa Coral. I am not sure exactly what they are but I would like to figure that out sooner then later. This way I can take care of it if needed. So far from what I have...

ID what’s living inside the Acantho and how I can get rid of it. Bivalve clam? Burrowing clam? Is it a worm? how do I get rid of it.

Hello, this is the predicament I am currently in: I contracted Acropora Eating Flatworms in late 2022 and have been dipping three frag racks full of Acro frags and colonies for the past 7 weeks in Potassium Chloride. I dipped in 1 TBS Food Grade KCl per gallon for 10 minutes each rack. The...
