nudibranch

Hello all. Well I'm starting to see signs of a pest in my corals. Could this be marks of NEM? What could be a useful in tank treatment? Thanks for the help.

My friend got this nudibranch, we believe from his live rock as a hitchhiker. i have put it in my tank to help ensure it survives. any idea what kind this is and how to care for it? thanks for any help!

Hi everyone. Need some help with an ID on this guy, and if it's a big deal he's their. If so, best action to take? Thanks!

ok so i’ve been thinking i have a 2.5 gallon tank and i was wondering what to do with it so my question is it possible to set it up as a nudibranch tank if i was to do this i’d either go with the zoa eating kind (i know it’s kinda messed up to have a bunch of zoas just to be eaten) or should i...

I ordered “bergiah” early this year With hopes of starting a nudibranch culture to deal with aptasia. I decided to order a pair from 3 different vendors in order to diversify my genetics. I believe I received 3 entirely different species. It seems one group was truly berghia, but I can’t seem...

My tank is currently fish-less due to ich and going through a phase of dinos (talk about struggling.) today I noticed a small green creature on the live rock. Thinking it was a nudibranch, I captured it with a pipette. Upon further examination, I realized I had no idea what it was. I found...

One of my Nudibranch doing work

Looking for help identifying what this is on my zoas. This is the first time I’ve ever seen them in the tank. Is this some type of nudibranch? Thanks in advance! #reefsquad

Is this a Berghia or zoa eating nudi?

Found a few of these guys crawling around this morning amidst the prazipro induced chaos.

Hello everyone! This is my first time on a reefing forum. I made an account because I can’t find any information regarding what’s going on in my tank. 32 gallon LED Biocube All levels are completely fine and the tank is doing great other then the literal 2 - 300 slugs that seemed to develop...

I have tried to get good photos for months since I saw the first one. I only see them when I disturb the aquascape but at night they come out in force. They're about a centimeter or less and bright solid yellow. Today I got a lens kit for my phone. I couldn't take a picture because I couldn't...

I discovered it, came with my corals, her name will be wormystein looks wormy and I'm dr.dendroSTEIN . Or what should it be called?

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...

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...

Hey you guys I made the awful discovery of Monti Eating Nudibranchs in my 55g tank. I plan on breaking off the dead portions, pulling out what I can to dip and scrub and add something to eat them. What fish can I get to help control/eradicate these little monsters? I've been told melanarus...

I have a bit of an Aptasia issue and would love to use some in my tank. Let me know if you have some available. Medium to large would be my preference, egg-laying age. cheers, Isaac

Hello! Heres my Chromodoris Annae feeding on a Random Black/Brown Sponge, If anyone could identify the Sponge it'd help a lot!

I just wanted to share my experiences with you all on the Hawaiian imperial nudibranch. I got this pair of nudi’s almost 2 weeks ago because I have a bunch of sponges in my tank and was hoping that these nudi’s would eat them as their known food source are sponges. They follow each other around...

I found (What might be) a nudibranch in my tank, after lights out on one of my closed zoas. Photos and video from my phone. Hopefully you can shed some light on this critter! *fork to help focus camera!* Here is a video of it: Is it actually a nudibranch? Is it one to get rid of? Thanks!

Looking to rid my tank of Aipastia and seems like this is one of the best and recommended methods. My biggest concern is they will become an expensive treat for my tank inhabitants before they get to eat the Aipastia. My biggest concerns are my Sally Lightfoot Crab, followed by my Coral Banded...

Things are getting out of control with Red Planaria in my 29 gallon reef tank. I've tried it all...manual removal which seems to be a daily chore, Flatworm eXit (multiple occasions), 12 line wrasse (casually grazes on them), but whatever I try I still find patches of flatworms on my rock work...

Sorry about the quality but taken with my phone at night with a flashlight

So I got a shipment in from the gulf region of florida and found a nudibranch. That's as far as I can get. It's not wearing a hat so I can't tell if it's a black hat or a white hat (dark side of the force or light side of the force for those that don't get the hat reference [ bad or good for...
