identify

This guy came in a bucket of love rock I picked up from another tank. I cant seem to find anything like him in my search. Picture is not great, but it is brown with white bands on legs and white dots on him. She'll is about 1.5 inches across.

So I know the picture is blurry but I can’t get a great shot. Found this little Slug looking thing in my tank today out of nowhere and wondered why if anyone can identify it and tell me if it could harm my aquarium?

Can someone please I.D. these pictures

On 11/18/19 one of the two clownfish we have in our nano tank started to act differently. Nothing has changed in the tank in the last month since having them. Parameters: Temperature - 78.3 Salinity - 1.024 PPT Ammonia - 0 Nitrite - 0 Nitrate - 2 ppm PH - 8.2 Symptoms: - Heavy breathing -...

I haven’t added any new rock or coral to my tank in months but today I noticed a bright yellow nudibranch about 2cm long moving across the back glass of my aquarium. The back of the tank is rarely cleaned so it wasn’t easy to photograph it through the algae buildup but here are the vest photos I...

Does anyone know what these little buggers are? They are very, very tiny. This is the best photo I could do on my phone. They seem to multiplying rather quickly.

Just fragged these zoas that I picked up from a buddy and need to know what they are before I post them up for sale or take them to the LFS for a credit. I tried looking around to find something online but no luck. If anyone can help ID them it would be greatly appreciated! (Only need to ID the...

So I was observing my tank and to my surprise I ran into something very strange that caught my eye. It seems to be a type of snail but without a shell. This “snail” is a little smaller than a dime. Help would be appreciated! It’s kinda creepy! *See images below*

Never seen this thing. Should I remove it?

Hi all, So I found this thing slowly crawling along the waterline tonight... It's about an inch long, but stretches out a little longer and shrinks back a little smaller. It looks like it has some little feelers/antennae on the front. I for sure did not bring it into the tank at that size...

Could you all help me ID this. It was growing around my mushroom plug. I pulled the plug and scrubbed it off the plug. I put the mushroom in a different local. I scrubbed the plug hole but it is growing back. Also if you can, please let me know how to remove it. For the record this entire rock...

anyone know what these black or dark colored bubbles are? they are not like air bubbles but more look like a solid but wanted to know if they are bad and should i take them out? I think they are bad since the torch they seem to be attached to looks like the stem has eroded or eaten away if these...

I was dipping my new christmas tree rock and this guy came running off. Want to play it safe so I have him in a breeder basket right now. Haven’t heard of any brittle star pests before, and I love to have them as they are great for taking care of detritus. Just want to know if it’s a pest and...

Any ideas as to this algae? It is red with long strings, 1-2 cm. No bubbles and not snotty so I'm hopeful it's not dino

I just got this acro in a trade today. Would Acropora kimbeensis be an adequate guess? Country of origin is unfortunately unknown :( Growth of the mothercolony is a somewhat high "table". If anyone has seen it for sale somewhere, the "designer-name" would be great too :) Thanks

Long white stringy creature living in chaeto. It retracts when I touch the water or it senses vibrations on aquaclear filter. Maybe some kind of worm??

Can anyone provide an ID for this bad boy? I got a frag of it and they called it tri-color valida which I don't think is correct.

Is this a (the?) culprit for my unhappy zoas? Pics not great, but 2 large antenna and visible eye spots. Could also be a slug -- the purple portion is almost firm like a mantle. As always, burn it, sump it or good guy?

Took a time lapse of one of the “unknown” polyps I found, still not sure what it is, lmk if u do.

Update: Upon further research, I was able to educate myself a little. It appears the snails are harmless and the limpets?; are as well. The flatworms though; not so sure. Hello all! Found a few new critters I haven’t noticed before. Seen a few of these little snails climbing around. They’re...

Hey guys. Posted in another post about QT'ing these corals. Figured I'd also post about identifying the exact corals or names. I know three are a species of Montipora and one is a candy cane. Just looking for specifics please. Also; ideal placement for each would be fantastic! Thanks guys. #1...

Just found this guy on the outside of my skimmer. He's from TBS Live Rock, so Gulf of Mexico. About 1cm, translucent-ish, pale cream/tan with crazy spikes & antenna. WHAT IS THIS?!?

Hi. These recently appeared in my sump. They’ve been stationary but I cannot figure out what they are for the life of me. They’re a clear/whitish color. Any ideas?

So I just happens to look in my overflows and saw a bunch of these guys could really use some help on identifying what I have going on and the negative effects, please. Thanks all

After feeding my tank last night, I noticed some motion and took a closer look. It was a long transparent tentacle coming from the live rock. The head was wriggling around pretty good. I took video with my phone, I apologize for poor quality. Make sure to view in 1080p: I've gotten pretty...
