identification

Can anyone help me Identify what this is on my hermits shell. I just ordered a clean up crew and this was on some of the shells.

I’m trying to identify this “thing”. I noticed it about a week ago and idk if it is a baby anemone or what. It could have been on this rock all along since we have bought it and we are just now are noticing. We currently have 2 anemones in our tank

I bought this bundle of zoa (I think? I'm very new), and after I got it home, I noticed that--in addition to the "main" polyps--there is a tiny patch of tiny TINY corals. (See the arrow/circle in the pic.) The main polyps in the pic are maybe half a centimeter tall (looks bigger in the pic for...

So I bought this thing that when happy, it looks similar to a rose bubble but it's got what looks like multiple mouths. Any ideas? Pardon it's so unhappy right now. Just swapped to a larger tank.

Hello all, I am looking to clarify exactly what each grade of RFA (or any nem for that matter) means. I know there are ultra and rainbow versions, what are the difference between the two? Are there more grades as well? Thanks in advance my reefing friends!!

So I’ve had my tank for about 6 months and finally added some “Beginner” corals. I have 5 new corals in my tank, 3 of which I’m not sure the name. Please help me identify the name of these corals! Thank you.

So came downstairs to my office where my reef tank is. Started the morning ritual of cleaning the glass with a coffee in one hand when I saw this little guy on the glass! So excited, I assume totally safe in a reef system? Anything I can do to help it out?

I recently bought a damselfish from petco under the dubious label "assorted damsel". I think it's a female because if the clear fins, and it has no yellow whatsoever. I'm thinking either a yellowtail or fijian blue devil. I need help :(

Hey, didn't know where to post this, but I was looking at this fish and was trying to figure out what it is and I basically can't. I've seen it offered for sale by multiple places as "vampire pseudochromis- Maldives" with the exact same picture. Thing is, it doesn't look like the typical vampire...

Just fragged these zoas that I picked up from a buddy and need to know what they are before I post them up for sale or take them to the LFS for a credit. I tried looking around to find something online but no luck. If anyone can help ID them it would be greatly appreciated! (Only need to ID the...

Today in my local fish shop I asked for easy corals to handle and he gave me these 3 mushrooms. He never mentioned what type, just said they were mushrooms. Does anyone know what type they are and how to handle them?

Hey All, I added a frag to my tank and have noticed some questionable algae. Can you please help me ID. I will share 3 different patches of Algae so an ID on each one would be helpful. To me pictures 1 and 2 look like Bryopsis and possibly 3 as well. If so, should I be removing the frag and...

Hello there! So not going to lie here I'm a little concerned about my father's reef tank. He started a tank last year in December, and after I considered it fish friendly. He went out and got a couple fish and a couple corals, threw them in the tank and called it good. I visit when I can but he...

Hi, When I turned off the light, this little fellow can crawling out of a rock! Planning on keeping shrimp larvea in the tank, but would like to know if he is harmful. Who can help identify this hairy friend?

I added a piece of macro algae to my tank yesterday evening and my one fish in the tank (clownfish) now has bumps near his gills the following morning. Did I introduce a parasite? Any help with IDing it would be helpful. The tank is just the clownfish and a piece of macro algae. Tank is 1.5...

Hi there! Can anyone help me out and identify the type of algae this is? My current solution has been to try to scrub it out of the rocks but in some places, it is in the crevices and it makes it very difficult, especially with the amount that exists. Someone had suggested it is purple algae...

I believe this came in hitchhiking on a zoa colony from vietnam but not to sure, I tried to get the best pictures I can and weirdest of all it seems to only be growing on the glass... maybe Bryopsis? But it has like a foot base then spouts little almost fans, very hard to scrape off Any ideas?

Hey gang, I’ve been running a Fluval 13.5 since March. My first two corals from Biota came with these little grass-like things on them, and being a total noob, I thought nothing of them. They grew to be quite long in one spot, and they’re starting to spread like little threads on my main...

Hello, I did an order though Live aquaria's Divers Den, and the fish I ordered was switched in their warehouse by accident... whoops. They told me I could go ahead and keep it, and that it was a Caribbean Striped Parrotfish. Looking at it though, I believe it is a Princess Parrotfish. Is anyone...

Picked these up yesterday, the guy at the LFS had no idea what they were.

I was thinking, and I want to revolutionize the hobby and start giving identification numbers to corals and the lineage to help preserve each species

Recently, this pink/purple foam thing started overgrowing zoas in my zoa garden. What is it? What eats it or removes it aside from manual removal? Here are photos of it on zoa frags I removed to clean. I'm thinking it is a sponge. I have been removing the impacted rocks and frags and...

Photo of algae from my sump. Backstory - chaeto didn't grow well. This popped up in DT few strands and began to spread slowly. I moved the rock with this on it to sump since it was obviously happy with my parameters. It has grown consistently however, nitrates remain high. Added ulva from...

I was dipping my new christmas tree rock and this guy came running off. Want to play it safe so I have him in a breeder basket right now. Haven’t heard of any brittle star pests before, and I love to have them as they are great for taking care of detritus. Just want to know if it’s a pest and...
