identification

Hello! I have a hard coral that I got from a LFS about 8-10 months ago. I honestly do not remember exactly what this coral is, and would appreciate some help in IDing it. It is also starting to bleach from the inside out it looks like. I have had 0 changes to my tank besides add a couple...

Hey everyone I bought some live rock a year or so ago from KP Aquatics located in FL. I put the rocks in my storage tank and have heard a pistol shrimp snapping all year, never saw him though. Just a few days ago I switched my rock storage to a new tank and finally found him. I know it’s a...

A little help with these two. Local LFS pickups. Im thinking maybe Glow Pops on the brown one?

Can anyone help me ID which Acropora species this is? The one in the center not the mille on the right.

Hello, Can anyone ID this critter I found swimming in my tank earlier. I caught one to see if I could get a better view, but there were quite a bit.

Hello, I just received a cleanup crew shipment and in one of the bags with a whole mess of dwarf ceriths there was what looks to be an extremely small clam. It's no bigger than a centimeter and I'm wondering if anyone knows if it will get larger or remain small. I placed it in my sand bed...

Hi. I have a spot of dark purple growing on my rock. It is covered in spines. Not sure what it is. Can anyone help?

Greetings, I know this forum is not specifically related to my question, but I would like to give it a try. I am a researcher working at GEOMAR in Kiel, Germany. I am mapping the seabed of Madeira (northeastern Atlantic) to identify habitats, and I have found several small white branched corals...

Hey all, I bought this tang from a popular online vendor. Sold to me as a dussumieri but I have my doubts. I think it may be Bariene or Mata. He's currently in an observation tank with a few other fish before I add them to my display. Any thoughts on a positive ID?

I have recently bought this crab from my LPS and they labeled it as a Sand Sifting Crab, which it is but I was wondering if someone could ID it so I can do more research on its compatibility within my tank. They told me they believed it was reef safe with caution, but they also didn't have much...

Curious as to what all these different critters growing on live rock in my NPS tank are? I know some are sponges but I’ve included pics of a few I’m not sure of. I’ve seen most of it here and there before but I feed my NPS tank consistently so I’ve noticed new growths popping up everywhere on my...

Whatever it is, it loves blue light. Didn't see these at all for the first few months until I switched to more blue-intense LEDs, then a week later they showed up. Does not form mats. Sort of bunches together in small green lumpy masses. Apparently hates shade, does not touch any shaded...

Please can someone help me identify what on earth this thing is living inside this small hole in my live rock?! Thought it was some trapped shedding at first but then it moved! The two ‘arm’ type things which are visible - one reaching to the side, the other reaching straight at the camera -...

I recently added some ocean aquacultured live rock to my tanks that came with all sorts of cool sponges tunicates etc. Added a really nice piece to my macro tank. I’ve noticed a few bristle worms crawling around when the lights go out which I don’t mind. I was checking for other critters last...

I'm new and I got these 4 zoas. But I didn't know their name. Please help! Thanks!

I just purchased this Balanophyllia solitary cup coral the other day and noticed it came along with this purple growth next to it. Just curious if anyone knows what it is? Definitely assuming it’s NPS Thanks

Hi, Today, I noticed my male mandarin died. I found him on the bottom of the tank when I woke up. It is a big loose for me, as he was a part of mated pair, which has been spawning several times. On 21.11.2023 I noticed ich breakdown in my tank. I have tried to manage it, and I haven't had any...

Hi! Like the flair says, a little bit of an emergency. Within the last 24 hrs, one of my clowns went from perfectly fine to this either growth or wound on her stomach. (Or best case scenario eggs? I know that’s prob not the case… However she is the female of the two). Other tank mates that I...

I just picked these stars up from the store earlier and noticed they have these weird polyp like growths coming off their arms in addition to the regular spikes. I asked the guy at the store and he said it may have something to do with breeding but wasn’t sure. Just curious if anyone else has...

Anyone able to identify what this is? I don’t really know how to describe it other than it looks like cotton balls on my coral. Guessing some sort of fungus? 14 gallon reef AIO, pretty new to all of this so any help is appreciated!

Crab came in on an order of Green Emerald Crabs Snail came in with an order of Astrea snails Any ids? Both are in my sump now

What kind of tang is this? It came in on a shipment with no name I was guessing maybe a bristletooth of some sort or maybe a juvenile yellowfin tang? Thanks!

Can anyone help with an ID on this? LFS lead wasn’t there, but they were sitting in the corner and looked pretty cool to me - reminds me of an old lightbulb filament. Color is an orange/red on a dark almost black background. Appreciate any help!

Hello everyone I bought a fish and forgot what kind it was. Hopefully someone can identify it. For the life of me I can't remember what is is called but it's really darn cute that's for sure.

I have recently ordered one from amazon, can anyone else give additional feedback about it in reef hoby especially? I recently had a dino outbreak - it forced me to consider a cheap microscope to make things easier with exact specie identification and same future things
