identification?

Had these guys for a while, they also go on my glass from time to time. What are they?

Can anybody help me identify what’s hanging out on this coral in the front? I just got it in. I know the one piece is bubble algae and I should just take it off but what’s the other stuff? Thank you!

Im baffled is this a diatom or what...

Does anyone know what this fleshy-looking spiral thing is, at the base of the duncan? Sorry for the blues/poor quality. I can try to get a better picture tomorrow, if it helps. I had thought it was a new head growing - it's been there since I bought the frag two and a half months ago. It's...

Almost looks like little brown bugs? The other thing I am wondering about is the white ovalish thing. the algae has been a problem too. Tough place to be keeping the tank, filled with sunshine

We have a tiny live rock that we have noticed some stuff growing on. Can anyone help us identify it? Our tank is about 1 month old. Thank you!

This looks more like a bug from the top and a snail from the bottom. color - black length - without antenna approx. 1.35cm. (with antenna-feelers stretched out approx. 2 cm. shape - flat-oval, like a bug had a strong suction on the glass of the tank is it a reef tank friend or foe ? Keep or...

Hi! Can anyone help me identify the red spot on the skeleton of my torch coral? They’re hard and won’t scrape off with my fingernail. We dipped the coral and it won’t come off either. Any help would be appreciated. It’s nowhere else within the tank and/or on other corals. Hoping it’s...

We bought a miscellaneous labeled coral, can anyone identify it? It doesn't look the best, is it dying? Just got it yesterday night.

I’ve been trying to battle this ‘brown algae’ for quite a long time now. I’ve finally gotten a microscope to observe all the cells in my aquarium. Does the picture below look like Dino cells. The cells do move around and they go away at night and come back in the day. This makes me think it is...

Hey guys, pretty new to reefing but I have an Semi established tank, I think it’s been like 4-5 months since I started with Tampa Bay live rock. But I looked at the glass today and saw something hatching? I didn’t see these eggs yesterday or last night but there seems to be little “sprouts”...

These white, spiky protrusions (to the bottom right of the cleaner shrimp) just appeared overnight in my tank. The closest thing I can identify it as might be a pink sponge, especially with sponge on the underside of the rock. Can anyone confirm? Otherwise, any clue what it could be? Thanks!

Hi all, I have been keeping freshwater tanks but decided to convert one (10g) over to salt last month, I'm loving it so far. That being said I'm still very new to this and was wondering if anyone would be able to help me identify this frag I picked up today? Additionally, how long should I...

Hi friends! I’m taking care of this tank at school. Was wondering if anyone knew what these are? Look like some form of anemone but I’m not sure. They’ve pretty much taken over this tank. Thanks in advance!

Can you help me identify this algae? It’s only on a couple rocks, I thought it’s bryopsis but I’m not 100% sure. Pulling it off the rocks is difficult but not impossible. The root system holding it down is very strong.

Hey everyone! Yesterday my boyfriend and I went on a coral buying spree :p ! The lady told us the name of this beauty, but I was way to excited and ended up forgetting the name! I think it was along the lines of “Yellow Eyed Monster” but I’m not 100% sure :) Any recommendations? Thanks!!

Okay so apparently I'm not as good at this whole identification thing as I thought...all these things are TINY. Like itty bitty micro tiny. Every photo is taken using a magnifying glass. Are these even living creatures or am I finally losing it watching rocks move? ...I probably should try...

Hello! Kinda new with the hobby and I’ve found these “Bubble” like things in my tank! Any idea what they might be??

Hi I just noticed these lines of eggs on my glass Are they snail eggs?

I’m thinking about getting a black widow anemone. How do I know I’m getting a black widow and not a rainbow bta? Help please.

Found these on an older piece of live rock that was given to me. Tank is 2 months old and the suspected hydroids are not spreading. Moved the rock to quarantine tank just in case. Any ideas on I'd? They are tiny and evenly spread out on the rock.

Hey all, I’ve had a tank for sometime now and just put in this new duncan coral, and I’m wondering what the exact species/family of duncan I have. My friend has one and it’s whiskers are very long but mine are very short. I’ve read stuff about flow and all that, but I’ve changed it around and...

I’m trying to identify this “thing”. I noticed it about a week ago and idk if it is a baby anemone or what. It could have been on this rock all along since we have bought it and we are just now are noticing. We currently have 2 anemones in our tank

Mystery paly or zoa had been growing and healthy for a year and a half however has been retracted for the past two months and has begun to stress a neighboring zoa colony. During todays water change I lifted their rock and from the new perspective saw a mass growing off the coral plug ckoing the...

Can anyone help identify these coral? Sorry for the picture quality. All I have is my phone right now. :/
