nudibranch

I have never seen anything like them, small green with blue dots, and look like algae. Don't seem to be eating the coral but what the heck are they?

Hello! A complete marine novice here! and new to the forum! I have a 2 month old set-up and I have just come across something that resembles a seaslug? I have tried to ID it but was hoping someone here can help? I have taken it out until I can determine that its safe, as I have read that some...

Does anyone know what this is? Is it a Berghia or should I remove it?

Strange black sea slug or nudibranch? Can't tell if this is a good hitchhiker or a bad one. Hanging out on the hammer this evening. It must have come in on a small torch coral, but survived a dip. Any ideas? Keep or jettison?

Hello everyone, I am trying to find out if these flatworms that have showed up in my refugium are dangerous. Both types don't seem to care about my zoanthids that are in here, they mostly just stay on this porous rock. One type is red and has a yellow or white spot and the other is reddish brown...

Hello, About three months ago I bought a lettuce Nudibranch which still seems to be doing well. Here it is: I bought it because I noticed hair algae in my tank (Which is now rapidly spreading...) and he seems to be doing okay on it. Whilst picking up a knocked over frag about four weeks ago...

Hey guys, I just picked up a plating monti. I get a picture up once my phone charges enough. But on it are 2 snails and a nudibranch. The nudi has white branches on its back. Can anyone hint to if it is a back nudi by this. again ill get a pictute up as soon as i can. also can sps be iodine...

Bought a piece of pipe organ coral today and this little guy appeared after I put it in the tank (stayed hidden throughout the dip!). Nudibranch? I'm not good with killing things, would it be horrible if he stayed in the tank?

Hi, I am cycling my tank at the moment (looking to get nitrates down). I noticed a tiny hitchhiker - less than a cm in length. Looks like a purple nudibranch. It has blue and yellow running down it's back (I would post a pic but I need 5 posts before I can :D) My question - should I remove the...

Walked in from the store to find this on my side glass. I have it in a quarantine bowl until I can prove it's not a bad boy. It is about 1/4 inch long, pretty yellow.. smooth body. Not sure what kind of nudibranch it is, but on my way to go research thought I would toss up a pic in case...

Don't Risk it! Dip it. Most reef tank owners do not have access to well-designed quarantine systems. Many times this leads to significant losses brought on by infestations. Dipping your corals in CoralRx provides a quick, safe and effective solution to minimize those risks. Coral Rx is not a...

I just googled "nudibranchs" and I was amazed at the photos provided, these things are every color and pattern you can imagine, and I was looking for an ugly little bug !

Just pulled this little guy out from some zoanthids... Bad or good?

This isn't my picture, but I found an identical one online: http://www.originaldiving.com/blogbook/wp-content/uploads/blogger/_W5eQgXOOGvk/TMqNuVc-X-I/AAAAAAAAACA/DJVO9v_J-hQ/s1600/Nudibranch%2B1%2Bcropped.jpg But I just saw this crawling around my tank. Anyone know what it is, and if it is...

my tank has a population of coral eating nudibranches that are reproducing rapidly, there are clusters of eggs over some of the rocks and i have removed about 7 adult nudibranches. Are there any fish or invertebrates that can eradicate these pests? They have ate a whole soft coral, all that is...

Had my tank going for over a year and this is the first time I've seen this little guy. I can't post a pic, so I'll describe him as an inch long, white, and looks like a bunch of points poking off of his back. Any idea?:bigeek: I tried looking him up but I couldn't find anything that matched :/

So i noticed this guy originally on my glass and hes been hovering around the tank, ive been him go over my clover coral but he hasn't damaged it. Any idea what type of nudibranch it is and if its reef safe? Thank you.

Ok so I have what I am fairly certain is a black margined nudibranch (Glossodoris atromarginata). I was told in the shop he was an algae feeder but no he is not. I want to try figure out what he does eat specifically because if he goes back to the shop he will surely starve since they don't know...

Hi, I'm new to the forum, but not new to reef keeping, although I have never progressed past amateur. Will try to make my post count, with valuable content. I'm currently running a 125 acrylic with spill strainers tubed down to a sump where make-up water and Aragamight are added, with a Rio...

After year of battling aiptasia it seems they are finally taking over. I have been reading about berghia nudibranch and I want to know if any fish are known to eat them. I have a melanarus and am worried I might be buying him expensive treats. Any other tips or info is welcome.
