creature

Today i looked at my favia and saw what i thought was debris, until i looked up close, it looks like it has a clear egg sack in between two black dots (eyes?) i took it out with tweasers and its about as soft as a brine shrimp, and same size. While pulling it out, it sticks pretty well for its...

Hii, I just found some really strange strings behind some rock work. It literally has the structure of spaghetti. My guess is that it is some kind of a sponge. Any guesses? Thanks!

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...

Hi, Put a new piece of rock in the tank recently and this thing has suddenly appeared at some point today. Anyone any ideas?? It looks as though it’s “breathing” in the video but I can’t be sure with it being on the power head. Every days a journey with a new reef tank

Hey everyone, my aquarium is about 1 year old, this thing growing on the glass since the last month or so. it would be great help if you could help me ID it. in the video in the last 20 sec, it is a bit blurry sorry, It is shot with a magnifying glass since it is so tiny. thanks

My tank is fallow right now and with no fish around, I decide to focus more on the tiny things around the tank. I am seeing 3 creatures that I am not sure what they are. Whatever they are they are all over my tank, one grain of sand can have around 6 (yellow line) every spot you see in the sand...

Found this 10 mins ago. There are a bunch of them. Seems like when the lights go out, they come out. Are they good or bad. Also, what do they eat and what is it? What do they do?

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...

We all like to treat our Coral with dip and maybe some of us don't do it or never have at all. I would like to know, what is the coolest hitchhiker that has made their way into your tank? Through buying Coral, live rock or live sand or anything. It would be interesting to find out if anyone has...

So I know the picture is blurry but I can’t get a great shot. Found this little Slug looking thing in my tank today out of nowhere and wondered why if anyone can identify it and tell me if it could harm my aquarium?
