nudibranch

I found some nudis while dipping my corals. I think these are Lettus Nudibranchs but I’m not sure. I just want to know if they are good or bad.

Hey guys - found this little guy on my porites (edit: bad diatom bloom) around a month after adding the last coral; any ideas what it is?

Can anyone confirm this is a nudibranch and bristleworm? Released during dipping of some frags.

Hi all reefers, Anyone knows the general name or species name for this sea slug/nudibranch? It’s in blue dotted on its back with black base body. Curious on its diet. Thanks

I'm in the process of setting up aiptasia eating nudibranch culture. I'd love some on egg crates. I'm willing to pick up or pay for shipping if there are enough

Hypothetically if you were Australian and you were struggling for months to find a distributor in your country to purchase a specific Nudibranch you have researched in depth, and it is illegal to import pretty much all marine animals in Australia without a license. And you didn't want a license...

I discovered nudibranches eating my zoa colonies. First instinct was to purchase a large Melanurus wrasse, but a week in and he still has shown no interest in the nudibranches or in any food yet. I am hoping this will change soon. I removed all the large colonies and did a freshwater dip for...

So I’m doing some maintenance today and I was moving my chalice when I noticed this growth on it. I’ve seen these guys on a rock I have in my sump that has fan worms on it so I figured they were baby worms until I saw them on the skeleton of my chalice. One was heavily infested while the others...

I've tried purchasing nudibranchs (Lettuce), but I've had no luck keeping them alive for more than a few days. Am I just not choosing the right one? Or perhaps, my tank parameters off? I keep acropora and softies just fine. I'm just not sure what I'm doing wrong.

Is this a lettuce nudi? Got it for free with some snails. Guess they accidently threw it in.

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...
