idenfitifaction

Can anyone tell me why these things are? There’s about 30 of them all throughout my tank, and they’re all about the same size. My friend says they’re aiptasia, but I like variety of opinions.

No tang police please, this is just the qt tank. Will be going into a much larger one soon. Can't tell if this is a Razor Surgeon or a Yellowtail. As its a juvenile, will his color change as he ages? Don't believe there will be any issues with my Kole tang but want to verify.

Hey everyone I’ve had my tank cycling for 2 months now and I’ve been pretty on top of cleaning my rock scape of algae and watching my Params. Today after work I noticed a ton of rusty colored algae plus some bubbles trapped into them is this diatoms or Dino’s and what should I do to solve this...

I went to an aquarium store and saw they had a bucket with live rock, a few had some corals in very poor shape like this ?mushroom? It was very pale in color when I first got it. Hence why I don't know what mushroom/softie it is and it wasn't sold as a coral.. just as 'live rock'. It was a...

Hey fellow reefers. I have a zoa colony and another single polyp that have white spots and I am not sure if they are just the way these are, or if it is a bad case of zoa pox. The polyps act happy, and are growing rapidly. I got these super cheap, so am ok with dumping them if they are going...

Found this worm-like critter on my new zoa frag. Made it through dipping and was keeping the zoa from opening fully. At night it would extend. Looked like it has tiny barbs on the tail with a bunch of eyes or eggs near the base. The second pic is through a microscope at 4x magnification after...

I need some help identifying the coral that is pictured. I was given this piece by a neighbor who decided to move and could not remember the name or type of coral that this was. I've tried searching, but I'm new to this hobby and am having a hard time finding something similar. Thanks for any help!

I know the pics aren't that great but its the best o can do. this stuff is a over my tank. it reminds me off the floaty part of a dandelion.

I was wondering if anyone has seen these before, the polyps are way bigger than usually play/Zoa, thanks!

I got these both a while ago and I forgot to ask for the names of the corals. If you can help me ID them, that would be amazing. I couldn’t get an amazing pic of my lobo, so I put three different ones.

Hi guys, for about maybe two weeks I’ve had thus brown stringy seemingly slimy like substance completely covering my tank. And I’ve tried everything just short of completely draining and bleaching everything. I have done a black out for about 2 day and nights. H2O2 dosing and soaking rocks and...

But now I’m thinking it could be a Acanthophyllia . Looking for some input

Sorry for the potato quality, the image looked fine on the phone. Anywho, I bought this frag as a 'pink cyphastrea', but the more I look around, it looks like a porites. Anyone out there that can help?

i found this monti at the lfs if it even is a monti. This lfs isn’t really known for their Nice corals ( hence all of the algae lol) but this one caught my eye. Does anyone know what it is??

Would love some guidance on what these are on my live rock. If you need better pictures or different angles let me know and will try my best. Picture #1 Picture#2 Picture#3 Picture#4 Picture#5 Picture#6 Picture#7

Ok so found this reef octopus calcium reactor at my lfs store for $99. I’m trying to figure out the model so I can find the manual. Let me know if it’s a good model or if I should pass. Thanks guys and gals!

Has an almost orange head and semi clear tubular body. On base of mushroom frag in the shade. Retracted when I picked frag up.

Hi everyone, I've been looking around on this forum for information quite a lot the last year, but never really made an account or had something worth posting. Now however, I've made a fairly worrysome discovery on which I could certainly use the help of some more experienced reefers. So, I...
