pest

I found this little creature crawling on my glass at night, and I believe they’re flatworms. Can anyone help ID this? Or at least tell if they’re harmful or not? It looks transparent/white with black dots on them. Doesn’t look like brown flatworm unless it’s a baby.

Just noticed a few of these popping up in my tank i can’t really tell what kind they are and what’s the best method removing?

ID ?? Thank you in advance!

cool video of my 1.5 year old mandarin eating some kind of worm from the rocks … what do you think it is ?

Hi ! I have a 18 years old 150 gallons tank. I never had any issue until a few months ago, everything went wrong at the same time :/ Probably got a power outage that went unoticed: my skimmer died + my heater went rogue (82°F). I was not there ... My wife did not notice for a week. At the end...

Hello, I'm (once again) struggling with poor PE and some tissue loss on my Acropora. First of all my tank parameters and my setup: 430L Tank Volume Very recent ICP: https://lab.faunamarin.de/de/share/analysis/115340 KH, CA and Po4 are fairly stable and I measure about the same as the ICP...

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...

Got a poccilipora colony the other day. Did an initial dip in 100% perxoide to clear algae then 15 minutes in CoralRX which blew off some debris. 2 days later on observation I noticed a lot of very tiny (pinhead sized) spots. I pulled the coral and did a 15 minute lugols dip and a ton of these...

I was trying to see if anyone knows what these are? I wanted to see if they were flatworms and if so are they harmful to my corals? Hard to see I just noticed them today

I don't know if these images are clear enough. New Zoa frag in the tank four days. Starting to open, but struggling a bit. Noticed these brown strands wrapped around the Zoas with these little black heads. Are these just zooxanthellae from an acclimating coral or something more sinister? The...

Hey all, assuming this torch is fine but curious as to what this is, not sure if it caught some food and is eating or if irritated, hasn't been retracted lately and all water params are in my standard range. Just curious to know if this can be identified.. TIA!

Clear tube looking things and a clear/opaque bulb looking thing on the bottom of my Alveopora

This guy crawled out my torch coral during a dip. Not sure what he is. Checked the guide and its not on there. Taken Coral RX 30 mins to kill it.

Hey, I've noticed some white spots on some of my acropora recently and I've caught some worms out of my tank using a turkey blaster - I'll attach some images. Any opinions would be greatly appreciated

Hi all. Only been into reefing for a couple of months. Watching the tank from a distance and seen my zoas starting to close. Saw this creature moving extremely slowly under them. Moved like a snail with really long hair like tentacle poking around. Photo to follow. Was searching as fast as...

What is this thing. I saw it the other day and thought maybe the coral was sprouting a new branch (still new to reefs) I realize that's probably not it. But it's like a orange swirl last night I saw two antenna things sticking out. Any one have any idea? It has a hard shell and it's like an...

Found in my sand bed. Never seen anything like it before.

Does anyone know what this slug looking red spec is. Just pulled it off my recently introduced Maxima clam shell. Little horns or eyes poking out from its head. Thanks everyone!

Looks like it’s stinging one of my dscisoma mushrooms back.. multiplied as well over the last several months.

This is my first tank and I have been keeping it for almost 1.5 years. I have no idea what these small black polyps are that are growing like crazy. They seem to be a small fast-growing coral that closes when I touch it. My LFS told me to basically perform surgery and get the zoas off that...

Looks like mojano to me but want to make sure as it is next to a ricordea Yuma , can anyone help ID here are the best photos I could get it is very small right now

Hello! About a week ago I took over a 4 year established biocube 29g. Wondering if this is aptasia or xenia. Water parameters: Temp: 77F Salinity: 1.026 pH: 8.2 Nitrites: 0 Ammonia: 0 Nitrates: 40 (they were 160 before a 50% water change and i’m still working on getting it down) Phosphates: 4…...

So this fellas is growing....fast. Like in a couple days double in size and showed up from nowhere. Any ideas? Growing on an Acan skeleton.

Hey guys & gals , happy weekend, hope everyone is doing ok Recently found this growing underneath one of my scolymia, appears to be some sort of sponge / truncate but wanted to post photos just to make sure it’s not something more invasive which warrants removal Here is a photo (attached) the...
