Over the last couple of months what appear to be little purpleish almost fuzzy looking spheres have started popping up on my rocks. They don’t scrub off easily, I’ve taken a toothbrush to them to see and it doesn’t really seem to have any effect on them. They don’t seem to be causing issues, but...

Guys!!! It’s been months! But I finally got a decent video of that darn work thing that’s always poking out the rock at night!!! It always comes from the same spot and seems to eat the left over food which is great! I am terrified that it’s going to take out some live stock though! Any ideas...

Hey y'all, was at my LFS and saw this little dude in a box with Trimma gobies. The guy told me what it was called, but I can't seem to remember the exact name. If I recall, he called it something along the lines of a "banded cave goby" but I can't find any info on it using that name. It's the...

Hello everyone! This is my first post, I decided to reach out and see if anyone can help my ID what is growing on the base of my torch? It has been slowly getting larger for the last 6months or so, now I am noticing a little bit of color loss in the torch and I’m worried this could be the root...

Hey all, created an account just to ask this. A few weeks ago I bought some urchins from my local fish store; The owner referred to them as "Spiny Urchins" informally, with the actual label on the tank being "Long-Spine Urchins (Diadema spp.)." They had red and greenish-black color variations...

Does anybody have any idea what that white stuff is growing on my frogspawn? Should I be worried? I’ve had it for about a month and a half and it seems to be doing great and it’s growing too. The stuff looks and feels like thread..

Hi, Would anyone be able to identify this species? It’s motile, green, and oval shaped. I cultured it in standard salinity saltwater. Other than that, I only have a Chinese name 扁藻. Sorry for the poor quality microscopy. Thanks, Adam

Hi all. Long time lurker, first time caller. Can anyone help point me in the right direction in ID ING the items in the pictures. All of these are currently in my QT tank. Seems like 2 odd things growing of my Favia and some stuff on my hammer. Any help is appreciated.

This was sold to me as a gbta but now I’m starting to wonder if maybe it’s something else. It has been the same color since I got it and it has not moved since it’s been in the tank. All of my water parameters are where they should be. It’s been in the tank for almost 1 month. I use an LED...

Hi anyone know what this could be growing on my rock…. Defiantly getting bigger. Cheers

Hey guys, so this thing is stuck on the inside of my tank’s glass. I have no clue where it came from and I have never seen it until just now, today. It moves with the flow of the water, but it doesn’t move locations. It’s just stuck in one place. Please someone tell me what this is, because I...

I have no idea what this thing is, i just noticed it on my frag, i dipped the frag before hand as i do with all drags but???? It’s creepy and I’m not sure if i should be worried. I tried to get a good picture of it but the lighting is kind of temperamental sorry.

Anybody have a clue what this long black tube thing is living in my live rock? Saw a clear looking one aswell

Can someone help ID this clam. I have 3 others 2 maxima and 1 Darsa but mantles look nothing like this one. If you zoom in the bumps on the mantle have an opening and look like mini bi valves

Can anyone I’d what’s growing in hermits back?….. looks like worm or brittle star….. there’s very fine fur coming of them

I just noticed white spots on the rock and snail right by the rock? I’m assuming some type of egg but i don’t really know? It’s just in that spot i haven’t seen it anywhere else in the tank.

Hey everyone! So I have this freshwater tank that I've been taking care of for about 5 months now, which I inherited from former club members (tank is school property, I just do the feedings and maintenance). It has had a green hair algae problem for years now, but we manage it with weekly...

I have absolutely no clue what these things are. They came on some LFS live rock, which I believe originated from the Indo-Pacific. They have no holes, feel quite tough, do not bend, and have small “tufts” on their spikes. They also do not appear to have grown since I introduced them a few weeks...

Weird mushroom looking things. Theyve been growing in that spot for a while. Not sure if bad or good or neutral?

I have a swarm of free swimming little white bugs in my tank and it’s tripping me out. They look like little white shrimp but hang upside down like mosquito larvae. Are they some type of pod? Or do I have a problem?

So today a cobweb like fluff has appeared I am unsure whether it is good or bad. I have trochus snails which have bred before which is a possibility. I have a pair of clowns, lawnmower blenny and Diamondback goby. I did have a big conch and nassarus snails but they never come out I don't know if...
