pest

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...

I have some acros/Millie that started looking bad. I dipped one and these worms came off they don't look like planaria though I do believe I have some in my tank. What is the best course of action?

I can try to get a better picture once the lights are on, but i've recently lost 1 hammer colony, and another that looks like it's on the way out. Params are all normal (Alk has been stable at 9.3, Nitrate 14, Phos 0.09, Ca 435, Sal 1.0255) and have been stable. All other corals are thriving...

Any idea what this is and if it’s going to be a problem? A few came in on a coral frag.

I have 2 mysteries today: 1. What is this? I saw it the other day looked like a very fine hair around d my zoa base. Thought, I got 2 long hair dogs, maybe a hair got in the tank and settle there. But today there are more about 7. 2 long 1.5" other short. See photo 2. Aphasia or feather duster...

Got you — here’s a smoother, blog-ready version that keeps your tone but cleans it up and flows better: I’ve noticed these worms in my sand bed from time to time during the day, but lately I’ve been having issues with some of my corals. Because of that, I started checking my tank at night to...

Hello all. I am starting a new tank due to pests I got when i was new to the hobby and didnt dip or QT anything (aptaisa, blue clove polyps, bubble algea, vermetid snails, red planaria) I am wondering if you all think dipping and scrubbing the skeletons ( mostly lps corals) and using hydrogen...

Sorry for the lower quality videos, it’s hard to get a good video as they tend to hide whenever I pull my phone out. I started some tanks with maricultured rock from Florida. Everything was going great until members of my CUC randomly died and corals seemed to deteriorate, despite parameters...

I’ve got an unknown creature invading into my ZOAs it doesn’t bode well and seems to really be irritating their growth in that spot. Google is failing me and all my searches end up at GSP. I am certain it’s not GSP and they almost look like mini palys. Any help would be very appreciated, and if...

Fowlr tank and im dabbling into corals to see if i like it and gonna be upgrading tanks sort of soon so, got a hammer and this "gsp"(its a branching one i think i dont see them too often) and only on the gsp im noticing these tiiiiny black dots kinda look star shaped but they are SUPER tiny i...

What that heck is on my urchin?? He has been carrying it around for almost a week and it has not moved. Its fluorescent and only appears yellow under blue light.

I realize I'm not going to win any Pulitzers for my photography here, but these popped up recently enough that I noticed them just 20 minutes ago. I have never had an issue with flatworms other than the ghost ones that don't cause issues, and that was years ago. I haven't added anything new to...

Hello all. Iv noticed my torch coral has been stressed recently for no apparent reason yet evething else is doing well. Yesterday i noticed this cluster of something and a small hole in the flesh of my torch. I came down this morning and the cluster of highlighted spots are gone. Are they pests...

Strange spindly white legs all over blasto. I noticed them after I fed and all the polyps were closed up digesting. Does anyone know what those things are? I sat and watch them for a while and they dont seem to be moving.

Hello, was inspecting some frags because I’m kind of OCD. I don’t have any pests in my tank as far as I can tell—except maybe THIS?! What is this? I used to think this was just a cutting mark where the piece was fragged but it never changed color, never got covered in the brown/green/purple...

Hi guys anyone can help to ID this white worm? No idea where it came from. Should I remove it?

Is this Aiptasia ? Good or bad for the tank ? It was small and started going so big and I see many new one started growing near by. Please suggest if I should remove it or leave it alone.

Hello guys, since one month, my Euphyllia started receding and doesn't extend anymore. Today, I saw something on the coral. I tried to take some photos to show you guys. Anyone can help me identify what pest is this? Seems like something is exiting from some sort of a nest! I don't want to...

Hey Guys ! Can you tell me what this is and if it’s dangerous? I’ve already scrapped it about a months ago but it came back, it looks like feeder worms but not sure

Hi, was just wondering if someone could ID this flatworm? At first I thought it was a Euphyilla eating flatworm but this one is on my Acanto.

Should I worry about these guys? Is it aiptasia? They don’t look quite the same and are staying rather small. Thanks!

How’s it going professionals! Been a while! That’s the good news, right? I just got these really beautiful Smurf blood zoanthid and hallucination zoas. Quarantined, acclimated, let sit in a little floater quarantine tank. About 1-5” from surface. They were fine for about a month. Keep in mind...

Was blowing my sandbed today and noticed this work with long tentacles, red/orange with black dots. Also attached to the bottom of my rock. Anyone know what this is and how to deal with it? Thank you all in advance!

They’re white, spreading, all over certain rocks and some of my snail shells. Before anyone suggests nerite egg sacs, I do not have any nerite snails. I don’t believe they are worm or snails themselves because they are flat, round, and with any orifices. I was able to break or “pop” one with my...
