identification

Hey, I just got a new frag ( very excited! Getting my first sps corals) I noticed that it had something on the side of it Lfs said detritus It’s crusty and hard feeling but broke up quite a bit in the Dip Any ideas if it’s an issue? Sorry I couldn’t get better photos

Found these hitchhikers today. Are they the bad stinging Anemones? Should I 86 them? Thank you.

Top part of the frag, translucent, never closes.

I got this gorgonian at an LFS and I’m not sure what kind it is. The polyps look purple and the spine looks white. The guy at the LFS said it was photosynthetic.

hi again yall! weird mucusy, matted web looking stuff in a low flow low light area in our tank.. been around for a little while, doesn’t seem to be bothering anything but it’s ugly & we are curious if we should remove this or leave it alone.. it’s somewhat like an algae growing.. fish, cuc, etc...

Picked up a new acro at the lfs they didn’t know the name of it, anyone can help me ID it?

Newbie clownfish questions (video below): *He's small, about 1", and been in the established 37 gallon tank for about 3 weeks. 1. Please help ID -- is this an Ocellaris? 2. To buy a friend now, I assume I need to get another small one the same size but does it have to be the same species (if I'm...

Does anyone know what this is? I found this worm just sitting out on the open on a frag tile in the frag tank. Their is now sand and zero live rock. It could have been introduced on a frag plug but I dip everything before it enters this tank. I’m just confused on how I’m just now seeing this...

Hello everyone i got sent two unidentified anthias by my seller a while back which at first i wanted to introduce to my fiji lyretail but found out they look a bit different. I do know they don’t always do well in pairs so if something suddenly happened i can move one of them to another tank. Is...

I bought a mushroom frag today which actually grew on a snail shell. I was debating on dipping it when I big Orange work came slithering out for the shell! Is this something I should try to get rid of with the dip or introduce to my tank? I currently don’t have any in my tank It actually looks...

I purchased this blasto during World Wide Coral's anniversary sale two weeks ago. After one week I noticed a red egg / growth appear on the base of the coral. The egg / growth in question is round, large enough to stick out from the base of the coral slightly, and has a small white thing...

There is a dozen or so of what seems to be flatworms on my favia. There don't seem to bother the coral at all. In opposite, it looks very healthy. And considering the number of them, it is not a recent development. I am not sure where they came from. What should I do about them? Dip the coral...

Hello, what algae is this and how do I get rid of it? thanks ;)

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...

I assume this is a clam because it opens and closes every now and then, but I don’t see any eyes. Bought it from a LFS as live rock, but it much have gotten mixed up. Any chance on ID/ how to take care of it in an establishing tank.

Anyone know what kinda tang this is ? Down here the locals call it a pepermint tang ‍♂️ what yall think! He is wild caught/collected it also hase some sort of fin rot ? Or what can that be ?

Can we compile a list in this thread of the different types of "Pulsing Xenia Corals". Please include common names and scientific names if you can along with a picture that you think is representative of that type. Any additional information/personal experience with that type of xenia would also...

Hi everyone, Does anyone know the species of this SPS? The owner of one of the lfs said he wasn’t sure what it was but it was super hardy (not sure if that helps). It’s my first venture into SPS and I wanna make sure I get it right. Thank you and Happy Reefing!

Need some help with what this orangish brown algae is and how we can fix it..if we need to? Tank is several years old, nothing has been added recently other than water for a water change. Seems to be spreading all over everything..

Hello, Not sure what this is and its all over!! 250 gallon fish only Nitrate 25ppm Alkalinity 9.5 Salinity 1.026 Phosphate .08 It does blow right off the rocks

So I noticed my clam was closed up today and upon further inspection I see these little rust colored what I assume are flatworms on it. Are these cause for concern?

Anyone can ID what type of Xenia this is? It was pulsing in the greenhouse when I bought it and when I first got it in my tank. It's been there 2 weeks now and hasn't started to pulse again.

Hello, New to the forum, so I’ll give an overview of my experience and self. I’ve fully immersed myself into this hobby for about three months now. I guess it was just a hidden passion that I had no idea I had. I am in the Navy! I’m stationed in Okinawa, Japan and am very close to the ocean...

Spotted this fleshy bubble looking thing growing from the skeleton on my torch. It’s the same color as the torch so I know it isn’t bubble algae. The pics aren’t the greatest but it’s glued down so it’s the best I can do for now. Any help on the ID would be appreciated.

I bought a coral from a place that only sells coral. My dad thought it would be cool to buy this and the employee who worked there said "its easy to care for". I don't know the name because my dad is the person who bought it. Can I please have help identifying this coral? I was thinking it was a...
