identifcation

Hello, I just got this leather coral from LFS and put it in my tank but im not sure what species it is. Could anyone ID it for me? Thanks!

I see a few different organisms and I’m not sure what’s good and what’s bad. Please help ID. I believe the stuff on the glass is pineapple sponges (good or bad?) but not sure on the other stuff

My uncle brought this coral back from Okinawa in the early 70s. It’s been in my family ever since. Now that I’m getting into the hobby, I’d love to eventually have this coral in my system. For reference it’s about 13 inches across.

Anyone able to ID these? First is a fleshy like lump with a red mouth like feature attached to my live rock, idk if it’s always been there but as some of my sea squirts fell off from pesky crabs is when I’ve noticed it. Bellow the bubble tip nem surrounded by the red. I’m unsure about this...

Hey guys, I’m from Brazil and bought this LTA anemone yesterday (aprox 1000usd), looks like a grafted nem, some tentacles are half green half purple, some completely green, looks crazy, never saw nothing like it. vendor called it nexus lta, has anyone seen something like it before ? Any comments...

These little white coils are growing all over my base rocks and my back glass, any idea what they are? I’ve tried picking them off but they won’t budge.

I’m QTing/Holding some livestock from my Dad’s tank that I’ve broken down. I have a variety of snails, hermits, a mated pair of clowns and a wrasse. I’ve found on the PVC pipes what looks to me like eggs. Anyone know who’s eggs they are?

Picked up this Acro frag for cheap from my LFS yesterday but they didn’t know what it was. Does anyone have any idea?

What is this bush that is growing on my rock?? It started small and continues to grow! Does anyone know what this is? And how to remove it?

Hey everyone, I have a clownfish pair that just laid their first eggs today (or at least first time I've noticed). I've read a bit about raising the fry, I'm thinking about giving it a try but it also sounds intimidating. Does anyone have any advice on how to move forward if I decide to try...

I have been watching these forums for a good while, but never have posted so this is my first post. I’ve recently had a very small worm hitchhike into my tank. Initially I noticed in in the sand and it was reaching out and hitting an amphipod. It didn’t appear as if it was trying to catch it...

I just bought these 2 at the lfs and the lady I talked to had no clue what they were, I’m hoping yall do!

Hello, I have had my tank up for 8 months now and I have what I believe is coralline algae growing. I just need some help identifying because it’s not bright pink. It starts off green then transitions to this grey on the glass. The stuff on the rock is bright pink so I am pretty sure that is...

Anybody know what these could be look like either some sort of filter feeder but I have no idea if it’s some kind of feather duster or what?? Thank yall!!!!

Hi could anyone help me identify this coral frag i got from my LFS a while ago. I was told it was a blasto but im not sure if the person knew certainly. Its been opening and feeding fine no issue. Just been keeping it in medium flow place mid tank for the meanwhile. Thank you to anyone who...

Hello everyone, do you know this coral? I think they are Acanthastrea Pachysepta but im not sure at all and google also isn't helpful. Thank you for your suggestions.

Tiny red worm that came in on a hammer. Can anyone ID this?

Bought this piece of live rock, and wondering if anyone can help me ID what these masses are and what all is going on with it.

Hi Brains trust I need some help in identifying (i think it’s a Gonipora) and recommended care for this coral ie recommended flow and amount of light My lFS told me high in the tank with ned to high flow but i am just wanting clarification Thankyou in advance

Hoping someone can identify what this invert is and if it’s harmful at all. Looks like a slug with a soft shell, snail without a shell.

I have started my tank on 1-February-2024: Red Sea Reefer Max G2+ 300. Pictures taken under white light. Thanks for helping to identify.

Could someone ID these? The first one has a fan like structure with almost luminescent coloring. The other two seem like sponges. The orange ones on my live rock have one or two holes and the white one has a lot. Any input helps :)

What are these Little Critters that are appearing more and more in my tank? Are they a pest or good ? If a pest what if best way to remove them
