idenfitifaction

Need help identifying what this is on/happening to my frag. Paramaters are ph 8.2, temp 25.5 c, 1.025 salinity, 430 calcium.

I've been having the Algae grow and i cannot identify it! I don't thing it's cyano because everything I read says it's green in freshwater aqariums but blue/red in saltwater aquariums. I dont know if I'm right or wrong but I recently changed from the red sea marine salt to the Coarl sea salt...

Hey everyone, new here- hopefully I’m doing this right and my pics will load. Recently picked up a tile with clover polyps, Xenia, and some Zoas/ palys. I didn’t really think much of the zoas/ palys as I had them years ago in another tank, but I’ve been reading up on palytoxin, and considering...

I found this thing on live rock that I bought and I can't find what it could be. First, it kinda looked like regular red coralline algae but now it seems like some kind of macroalgae. It grows attached to the rock. Any idea what it is? Could it be harmful to the tank? Can I help it reproduce...

Got this lfs, been growing like crazy but i can't find anything about it online. Any one ever seen this before?

Good morning Reefers! I have a 32 Biocube that's been running for a month now... live rock donated from a friend's tank. I LOVE all the life that came with the live rock, but I have NO idea what most of it is. There's a white (almost slime-looking?) growth that "sprouts" little tree-looking...

Hello Everyone, I recently set up a frag system and am trying to be very thorough about quarantining everything I introduce. A few months ago I purchased a chalice coral that has now been in quarantine for 60 days. Overall the coral appears to be in good health and has even grown a bit...

This crab came in on an alvepora I got at the lfs today. tossed it in the sump for now. Is anyone able to ID for me? Thanks!

Several of these jumped off a small rock I removed from my tank. Can anyone ID this?

The guy is thinking it's Fruit Loops but I have no idea. Obviously it is the circled frag.

Any idea what this little worm thingy is?

Hi! I’m a new member to the reef world! I noticed a nudibranch in my tank tonight, but I was having trouble identifying what kind it is. I think it’s an aptasia eating one (Berghia nudibranch) but I wanted to be sure. Any ideas?

These things have been slowly growing and spreading for a little while now. Any help identifying would be much appreciated.

Let me know if you need better photos. These keep multiplying and I’m wondering what the heck they are. They are little white pills that have been very very slowly move and quickly multiplying.

So I got zoas from a guy he said they are rainbow infusion, JF Daisy cutter, rainbow hornet zoa, pink diamond, fruit loops, JF mind blowing palys, and JF crazy lady or magician? Just wanting to see what you guys think these zoas are? I know some aren’t opened up and that could be some of the...

It’s small, but I have no idea what it is. The polyps are way more red in person than in the picture. Thanks!

I made this account to ask if anyone has bred Arrow Crabs before? We had brittle stars, fire worms, tube worms, bristle worms as hitchhikers in the live rock but now there is hundreds of tiny things running all over. The arrow crabs had babies twice and is pregnant again. The tadpoles were...

Heyehey could someone ID this zoas??? Thanks.

Hi, I’m trying to identify a tiny worm. I added some live copepods and 1hour later my tank is covered in thousands of these tiny white worms. I’ve tried to get some good microscope pictures so maybe you could help me! Thanks!

Hi all, just traded some corals with someone and he gave me this zoanthids as a gift. However, I’m not really sure what kind of pink zoanthids these are. Are they just “pink zoa’s” or do they have a more specific name? Can’t really find it on the webs. Thanks! (Scopas for size )

A few pieces that i'm having a hard time ID'ing and was wondering if anyone else has a clue?

Sooo I haven't been able to conclusively figure out what this is, answers have varied widely. What are these things? Hasn't harmed anything yet and I thought it was just a type of algae, but last night I saw a worm poking out of the rock near it. It seemed to be searching for something, poking...

I got 20 pounds of live rock that came with a ton of cool mushrooms and I put it in my qt this morning when it was still dark I saw this caterpillar looking creature that is red with white spots and horns I've looked for hours what it could be but I haven't matched a picture yet can you help...

HELP! I bought a 20 lb live rock that came with a bunch of mushrooms and than this morning at around 5:00 am so the lights were still off I saw this red and white creature come out looks almost like a caterpillar and has spikes....I tried to identify it but I can't seem to match the picture with...

Is this Gracilaria Curtissiae ? need accurate Id but I’ve been calling it Gracilaria. LFS calls it dragons tongue. And is anyone interested in taking some off my hands? We’ve already fully stocked our LFS and it just keeps growing! :) Side note: we keep a natural tank with pests such as...
