identification

Was wondering if someone could tell me what this is, i remember it started with a 'L' but i just can't find it, thank you all so much!

Hi all, I picked up a new piece from the LFS this Friday. They had previously cut off a hunk (about 2" x 1" x 1" - like half of a tennis ball and hollow inside) from a large, established coral (maybe 2 feet all the way around!) that I bought. NOT sure what this is, but I'm guessing some sort...

Hi, I just got a new frag for my tank and bought it as a hammer from my LFS. Upon more research and inspection, I think it may be a frogspawn hammer hybrid. Can anyone ID this Euphyllia for me?

Yet another person in need of an Algae ID. I have reviewed things online, and I'm just not skilled in the art of ID apparently. I do have a microscope, but I'm not sure what areas need to be photographed that would help. So, here are some in-tank, on a white paper plate and then under a...

So I know I have other issues I'm dealing with but I looked in the tank and seen this! I have no idea what it is or what I should do about it. Please help.

Is this a lettuce nudi? Got it for free with some snails. Guess they accidently threw it in.

I was topping off my tank and noticed these little white specs crawling all over the glass. Not sure if they are good or bad, please help identify and share treatment plans if needed. Would be much appreciated thank you!

My mom's friend knows I have a reef thank, they sent my mom a picture of this fish to ask me what it was and tell me I should get one. its a cool looking fish, don't think I want one though. given the coloration I am guessing its probably venomous. Either way, I would like to know what it is.

Hey! Anyone able to help identify this torch? Look like a grail?

I recently received a new coral for free after buying a new Prime 16HD, Trying to figure out exactly what this coral is since I'm new to saltwater. I currently have a EVO 13.5 and have the prime mount 10 inches above water, Any tips for acclimation mode and Lighting programs? I have GSP, ORA...

Hey reef fam need an ID on this yuma shroom!

I found these two little fellas at my local pet store and they were so pretty and fluffy and pink I brought them home and put them in my reef tank. They are growing like crazy and I have no idea what they are. I’m including pictures from front and side and hopefully you guys can help me out...

Anybody know what these are? They’re about the size of a nickel. Neon stalk/foot and neon mouth. White spots on the tips of the tentacles.

Don’t know what this mushroom is , need help IDing it . It’s more red but the skirt has green

This pic sucks I know. But if anyone can even get me close I’d appreciate it. Another 5$ frag I picked up. It’s the super orange small head in the middle. It’s not fire and ice it’s center is almost completely a radioactive orange with a dark blue skirt.

I got this frag for 5$ this weekend. I’m amazed at the colors but I have no idea what it is. Can someone please help. Tagging @footgal for obvious reasons.

Bought this at a market in Bangkok. Assumed it was Fungia but its attached to the frag plug with about a cm tall trunk. This surprised me as I had thought Fungia are free-roaming. It is about 4cm wide. Could it be a juvenile stage Fungia? Also, please ignore the bubble algae. Am working out a...

Hi about 3 days ago these zoas stopped opening up all the way and looked odd maybe deformed. The tank is fairly new maybe a little over 4 months now, so these zoas we're still growing on the plug. I noticed that there was a couple white sponges growing on the back and the side of the plug as...

Can someone please tell me this is a Zoa and not a pest. It just popped up from the live rock I got. The rock was in water at a coral shop.

I bought about 25lbs from gulf live rock and 4 of these anemones came on one of the pieces, can anyone help me I.d. Them? I cycled the rock for a week and all 4 survived.

Hello, I need help identifying something on my Potter's Angel please! I purchased my Potter's Angel on 01/16. He is in a 30 gallon QT, Aqueon HOB Filter, Whisper air pump, some plastic pots for cover and a small piece of live rock because many say that they will only graze. Weekly 15-20% water...

I’m 2 weeks into cycling a tank and I just put in a tiny piece of LR in today 5 hours or so ago and I did see a couple of those more shrimp looking pods that crawl around on the rocks and in the sand. I crushed up a couple pellets and dropped it in to continue feeding the cycle and now I have...

Anyone can tell me if this is a torch or a cristata? The tentacles are really short. Looks like less than an inch.

I was sold this as a ‘gold and green’ torch from a local store. The colours were a lot less vibrant since settling in my aquarium. It is definitely more of a yellow than gold... or close to a 24k Aussie? But has a green/turquoise base to it. I have Indo and Aussie HG in the tank but to me feels...

Anyone know the ID? Someone said reverse gorilla nipples but it doesn’t match exactly. Mine has more green yellow inside(sorry i cant see certain colours so im not sure). Looking for another guess or opinion. Thanks
