Hey guys, i just found those 3 guys that i’ve never seen before. It’s been at least 3 months that nothing went in the tank because i was busy with school and my time for tank went south. First 2 pics are, same guy, different angle (i think limpet). Middle 3 pics are, same guys different angle...

Hello I found this little bug / insect thing I’m my saltwater tank. There are also much smaller white ones in the tank and it looks like its offspring. Anybody know what this is?

What is this? I saw this on my rock. Is this a bad thing or a good thing? If bad, how do I remove it?

I just got this frag yesterday and I saw these today

Hey guys, I have got hundreds of these little critters on my tanks glass. I have no clue what they are. Please assist.

Was chilling in front of the tank this morning and observed some spawn being released. At first I thought it was brittle stars spawning which I’ve seen them do before. When I looked closer I saw a small round critter, with antenna, and these two pink protrusions where the spawn was being...

Hello there. If anyone can help identify what this is on my glass. It's not air bubbles. They seem to be swaying and sticking to the back of my tank. Also note that we have added trigger pods about a month ago in the back of our AIO tank. Tried getting a better picture in clearer lighting but...

Just noticed these hanging off my Zoas today. Tank has been fine, I’ve got 10 trochus snails and 2 clowns, zoas, and an elegance. Found 1 aptasia and a majano which I’m dealing with, just in case that could be the cause. If you need parameters, let me know!

Hey all, I’m transferring some stuff into another tank and seen this guy slithering? Anyone know what the heck this creature is?

I woke up this morning and found 14 of these strange little guys creeping up my glass in my saltwater tank. Can anyone help ID these? I have searched high and low and can not find anything similar. https://studio.youtube.com/video/5a9Hveudz3s/edit

Noticing this thing growing in the tank out of nowhere. Not sure what it is?

Pretty much what the title said. Looks similar to a mite and appears to be attacking dinos. I attached a video below. Please pardon the random movements because I lost the creature and was looking for it again. I can’t attach a video because the file I have is too large but I will attach a...

I try to look at my tank at night when everything is off because that’s when everything comes out, I saw these crawling all over my frags of zoas one of them is kind of fluorescent with I did not like because dosent that mean it’s eating my zoas? But they just look like pods of some sort to me...

I’ve had my tank set up for over a year, and never had added any crabs. My tank is a mostly fish only tank, with 2 anemones and some GSP. So I was caught by surprise one night when I spotted a mysterious crab on the rocks. My theory is that maybe when I was adding pods to the tank, there might...

I keep finding these white fuzzy type things all over my rocks and I’m concerned about what they are, hopefully you can tell what they are in the pictures, if not I will try and take better photos

Hi All - I have these tiny critters running around my sand bed. They look somewhat transparent but with a red/brown body. Look to be more walking vs. wiggling and tend to see more of them when I feed. In the attached video you can see them in the middle to lower third of the video. Any idea...

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...
