identification

Can anyone help me identify what is growing on the bottom of my acan? Almost looks like slime but it's the first time I've seen it. First timer in the hobby so not family with all pests or diseases. Thanks in advance.

We've had this toadstool a while now but never figured out which species it is. It is big and extremely wavy in the flow. Thanks

Hi all, I purchased a new fish yesterday, thinking it was a 6-line wrasse. It is not. Any help on the ID would be appreciated! White body with lateral black lines, 3 per side. Dorsal fin also has black lateral line. Some black spots at rear coming from the lowest black line. Head and neck...

This thing has been growing between my sand and aquarium glass. There are two smaller ones like it that I can see. What is it?

Trying to id these things on the glass. The close up is 10x zoom.

It's been a while that these white dots started appearing. At first I thought they were copepods so I just let them be. But looks like they could be snail eggs or something. I have astrea and trochus snails, bristleworms, lots of copepods and amphipods in the tank so could be one of those...

Hey, noticed this fuzxy growth growing on my clove polyps, the polyp that has the most of it won't open. Any idea what this is or what to do about it?

This Acropora was sold as a WYSIWYG colony, simply under the label "Acropora Sp." A month ago. A month later, Coloring up Any thoughts? My own best guess is Acropora tenuis maybe?

Won this coral by bid just over a year ago. It was listed as ‘yellow eyed favia’. It was like 1 inch in size when i got it. It grows slow but it suddenly will have a growth spurt sometimes. Its now on a 2 inch plate cause it over grew the one it came on. I realised the polyps are getting bigger...

Got this head of tank cultured ‘bicolour hammer’ from a home based coral aquaculture guy. I swear it has tips like a hammer but they’re small, thin and are so long? Like 1-2 inches long. Anyone have a hammer like this? Its like a hammer had fun with torch lol. It does not open and sway like my...

I’m going on a month and a half of Dino’s. I finally picked up a microscope to help identify what kind they are. Can anyone help ID these? It appears like 2 different kinds. Too hard for me to tell. Thank you

I just noticed this orange glow under the night lights of my aquarium. It’s extremely difficult to get a good picture of it under any lighting. It is located at the bottom of a base rock. it has orange polka dots around a dark middle part. It doesn’t move at all either. Super curious as to what...

Hi, Hi, i’m currently batteling dinos and I was wondering if you could help me id these. Zoom is 250x. My guess is amphidinium small cell.

Ahoy, I added a Duncan to the tank the other day. And when I was on the way home, I looked at the bag and saw a few hitchhikers. Was already planning a coralrx dip so wasn’t really concerned. seems I bumped of a snail or 2 which I wish I would have kept. But I also saw this thing that looked...

Lfs just calls these guys African clownfish. Are they clarkii or allardi? Or something else? Thanks

I had been eyeballing this guy for a while. I have a thing where I will pass fish through many visits and of they are still there they are apparently meant for my tank. The lfs said he was some sort of saddle back but I can not for the love of me remember the name he said. I appreciate it.

Hello all, first post and first tank. While I have a bit of experience maintaining other's tanks, this is my first personal tank. Any and all advice is welcome It's 27 gallons(or so I was told), and has a 3 chamber filtration system in the back. Standard cube tank from what I've seen, and I am...

I recently inherited a saltwater tank with this coral in it. The previous owner did not know the species of this particular coral. Its health has been declining over the past year, and I would like to know what specific coral it is to determine how best to take care of it going forward. Thank you!

Found dude bro in my tank. Not sure what he is, if he’s harmful or what he eats but I didn’t put him there and my puffer is very interested in him. He took a couple bites out of him in the video. But he has tiny little black eyes and what seems like a hard back the puffer couldn’t bite through...

Found this little guy while dipping my newly bought Trachyphyllia. Can anyone confirm if this is gorilla crab or any other species? He is very small, body is ~5mm in diameter.

Hello! I received this skimmer from an acquaintance and it looks rather old. However, since it was free I’d like to see if I can use it. I’ve noticed it is missing some pieces. I haven’t taken the time to clean it yet either. I just want to know what model it is so I can see if I can run it on...
