identification requested

I purchased what was sold to me as a Carpenter Flasher Wrasse almost a year and an half ago. It originally had deeper colors with almost a purple hue and blue lines that don’t show well in the picture. It also had a longer dorsal fin. Once acclimated the colors pretty much faded away to what it...

Can anybody help me identify what’s hanging out on this coral in the front? I just got it in. I know the one piece is bubble algae and I should just take it off but what’s the other stuff? Thank you!

Anyone know what the little stars are?

This orange stuff appeared in a new tank (1 month) overnight. It looks almost like something was dropped in the tank but it is pretty secure and we wouldn't have made a mistake like that without noticing. It is right under where the urchin has been sitting so maybe its related? The copepods seem...

Buddy of mine gave me a monti frag , he thinks its a detonation monti. Anyone with more experience can give some input? Its my first sps and first time dipping into sps after being nervous about it for so long. It looks red and dark green polyps to me.

First time posting, I hope this is the correct sub forum. I found this little hitchhiker hiding in my GSP rock. Today it was snacking on my hammer so definitely not friendly. Can anyone ID it, please? It's not a gorilla crab, and someone on Reddit said it's a Calico crab. I'm in Southeast...

Hi All, Today I pulled out the stock media shelf in my BioCube 32. I bought the InTank media basket to replace it. I was very startled to see all the creatures attached to the shelf I removed! There were a lot of pineapple sponges. And some other creatures?? They almost look like unhatched...

I got these guys all 50% off from my LFS and have a vague idea of the types but wanted to get confirmation from more experienced people! Also, for those who ID them, could I get some advice on placement/care? My ID’s: Front (green, metallic/stripy): green leptoseris Left (red with lavender...

Hi there, I seem to be having a slight bloom of algae in my tank. It looks red in my tank which makes me believe it’s cyano but it’s not like slimy, more like hair algae. I have included a picture of the algae under the microscope and what it looks like under white light. Let me know if anyone...

Hey Everyone! I came back from a vacation to notice what looks like a bunch of dragonflys swimming around in one of my tisbe cultures. They swim around in pairs like mandarins with little 'wings' on their backs. I'll try to get better pictures and videos when I'm home later. Any idea what...

Hello! I've recently purchased a coral which I removed from its plug. saw a small dot and thought no big deal, 3 months later it's a bunch of tiny mushrooms alongside feather dusters. I was told it's a expensive mushroom such rodactus, it's an anenome, and the such. does anyone know what this...

I'm a little confused about the names of corals. Please help me figure it out. The first question concerns the briareum and clavularia. How to distinguish them and who is who? The second question relates to the clavularia. Do I understand correctly that both of these corals belong to the genus...

In person it looks like a white blob with little spiky looking extrusions. assuming its a sponge? I've noticed it not filling out as much as usual. TIA!!

I am having issues battling dinos and I finally got them under a microscope. Think they may be Prorocentrum? Need some help identifying and treating because I really don't want to break down the tank and I cannot remove sand bed because I have wrasses. Equipment: Red Sea Reefer S1000 G2 ~265...

I have a few critters to ID and I hope none of them are bad. I have supplied a slew of pictures, with no clear meaning or direction. 1. I have a few clear/gray blob things around my tank that are just popping up and I’m not sure what they are. 2. I have a few root-like structures around the...

Hey guys this guy was a hitchhiker on one of my feather dusters. It appears to be a type of mushroom but I'm not entirely sure. It was attached to a very small pebble so i glued it to a frag rock. Base color is a blue-ishbrown with green tips. Any info will be appreciated, Thanks

Can anyone identify what this new brown substance is growing between the heads of this blasto? Recently started feeding heavier to increase nutrients for my SPS which were losing color. I've been seeing more algae and Dino growth, but this is new. 200 gallon mixed reef Live rock is 2 years...

I was at a local aquarium fish market a while ago and saw a super interesting type of "dragonet" as the person in the shop said, although they call anything they don't know what is a dragonet. It looked almost like a puffer fish mixed with a mandarin? It had the size and complexity of a mandarin...

This white translucent mound popped up overnight. Tank is well established, without any major issues for the past 2 years. Any ideas? It seems rigid and sprouted from one tiny stem like branch. There has been no change in size over the past week.

Noticed this scurrying around my glass recently. Are they flatworms and are they cause for concern? I have had a string of bad luck lateIy and I am currently treating the tank for Bryopsis and Dinos.

Hi guys, I suddenly found some small creatures on my tank glass and they are eating like a snail (but without shell). What are these? Should I keep them or eliminate them?

No bubbles in this stuff except when matted on algae. It is a fluorescence orange when under blue light. I'm stumped and thinking it's cyano or maybe some kind of dino. any help is greatly appreciated

Please help me identify this Conus species found near Kapalua, Maui (I think). No, I am not the Darwin Award wannabe holding it.
