idenfitifaction

Hi folks, New to R2R and learning a lot from you guys. Thanks a lot. Started my cycle 4 days ago and spotted these orange spots on the sand tonight. Can you guys confirm those are diatoms? If I understand well its a good sign so I would be happy about it, just need an expert eye. The orange...

Hey everyone, I was looking at my tank today and noticed this weird green and red slug looking creature. Anyone know what this is? Any help would be greatly appreciated!

I'm thinking it's a Monti, but not exactly sure or even what kind of Monti if it is one. Any help would be appreciated!

Are these vermatids snails on my hammer coral? i recently found one on a candy cane and immediately superglued the tube. this was about a week ago. Today I saw these little growths on the base of my hammer. Was hoping I was quick enough on stopping an outbreak but now I’m getting worried and...

Anyone know what these are? Offered in a trade to me asp what they are worth. Want to make sure I’m being fair to someone I’m trading.

My beautiful frogspawn is not happy. Its done really well for the few months I've had it, extending nicely and even looks like one of the heads is getting ready to split. Up until about two weeks ago when it started to look irritated, it had a couple vermitide snails on it, so I took care of...

Hi! About a month ago, I found this weird red-ish orange disk in the sand near the glass. It was before I had an account here, so I had no one to ask about it. I took some pictures of it, but it disappeared when the substrate was disturbed. (I'm assuming it was buried) Last night I saw it again...

Hi, I bought a new lobophyllia today and after drip acclimating it for 2 hours, popped it into my tank. After about five minutes a flowery thing popped out of the side of it, is this a feather duster? If so are they harmful or not? (Btw I dipped the coral for five minutes in aqua forest protect dip)

I just noticed two little clear tentacles coming out of the base of one of my corals. They are kind of thick and have darker tips. Are they sweeper tentacles? I was under the impression that they would only come out at night. Also, they sway around with the current, if that helps. Thanks for the...

I won these mushrooms in an auction sold as a reef koi bounce. It doesn’t look anything like a reef koi bounce online. Any ideas on what type of mushroom it is?

Hi. This is my first post on reef2reef. I normally browse but never contribute. Iv just discovered a white substance which looks gooey behind some of my live rock. I spend quite a bit of time admiring my tank so I feel its appeared quite quick. Everything else in my tank seems fine. All my soft...

Hi. Ive realised some "growth" happening on my clam shell and live rock of my Yuma Coral. Im not sure what it is and it just started to appear like a week ago. On the right seems to be the "tube" thing and on the left is the furry stuff. My yuma and clam is closed up cause I just turned my...

Hi, I’ve just finished cycling my tank and I’ve put a grain of sand under the microscope to see this? There like little bugs zooming round near/next to the grain of sand. Anyone know what it is? Is it bad or is it the bacteria that came with the live sand? Thanks :) Here is the video of microscope:

Hi. I havent added anything new in my tank for a month or so ++. I woke up this morning seeing this little dude on my glass and Im not sure what it is. Is it reef safe? Should I remove it or is it a good CUC? Thanks in advance! Sorry for the picture quality, its not that big. Ignore the curved...

Hi guys, I've been reading this group for many months.:) 6 weeks ago I started my cycling of a 43 gallon tank without fish and with dry rock and live sand. There is no longer ammonia or nitrites and nitrates are at 100 ppm (Red Sea) and phosphates are barely detectable, 0.01 (AF) or zero. For...

Hello! I am facing some type of algae that I’m having a hard time eradicating and properly identifying. But first some tank back ground. My tank is a Red Sea reefer 425xl. It has been running for 148 days. Up until last week my nitrates and phosphates had bottomed out to 0. As such I have...

Anyone know how to identify the sex of Mantis Shrimps?

Found out I had aiptasia yesterday so I figured I might as well ask what’s growing on my snail also. This is the only snail with this growth.

Tank is 6 months old. 65 gallon with 20 gallon sump and about 40lb live rock, 40lb live sand, two black phantom clown fish, two Bangaii Cardinals, one Tail Spot Blenny, one Royal Gramma, 2 peppermint shrimp, 3 hermit crabs, 10 turbo snails, 2 nerite snails, 2 cerith snails, 3 zoas, 1 radioactive...

Trying to figure out what this is. It’s twice the size of my fist. It has 8 heads and weights like 3 lbs. what is it and how much are they worth?

My LFS gave me this dying frag about a month ago, this polyp was a tiny spec of red and now it’s grown, it’s part of a larger dead section seen to the left and above it. I’m looking for an ID. During the day it opens more out and looks like a flat red disc w this green center. There’s another...

I bought my first ever coral about 4 months ago, a small 2 head Torch and a fungia plate coral, I dipped them both and got a small flatworm off the torch luckily. A few days into owning the torch and watching it get used to the water and extend, I noticed a little section of bristly exoskeleton...

I assume this is a clam because it opens and closes every now and then, but I don’t see any eyes. Bought it from a LFS as live rock, but it much have gotten mixed up. Any chance on ID/ how to take care of it in an establishing tank.
