what the heck is this? (1 Viewer)

[cope]

and should I kill it? or is it good..... it looks like a slug.... I just saw it today.... It is kinda cool looking... I put it in my sump for now...

 

[cope]

what I think is cool about saltwater.... the more you look at the tank.. the more stuff you find that you never knew you had.....

That appears to be a nudibranch; not sure what kind, some one else may be able to identify if it is a threat to your corals.

nudibrachs are pretty hard to id. i would suggest that, since it is getting cozy with your zoas, it's probably a zoanthid eating nudibranch. i would kill it immediately if i were you. additionally, i would pull the zoa colony out of your tank and dip it in a saltwater/iodine solution for about 15 minutes to make sure there are no more on that colony.

 

[AquaNerd]

yes...zoa eating nudibranch

this thing is 2.5 inches long prob the size of your pinky finger.... those zoanthid eating nudibranch say they are .25" long...... I am doing some research.. thanks. anyone else please respond..

I got him out... he is in a jar now... I am headed to the fish place...... this thing crawls like a slug but also swims.... just measured him.. 2.5 inches long prob as round as a small marker... (sharpie) very unusual looking.

size

better picture for size.... If he is good ....I want to keep him.... don't want to kill something just because I am unsure....

 

[cope]

My thought would be.... he has to have been in there a while.... to get this big..... none of the zoa's have been damaged....the tank is now almost 3 months old... Hitchhicker..

more stuff

in my sump.. I noticed these guy... they are the size of a sugar ant... and move about as fast... never sit still.... I have noticed a hand full .. I am sure there are more... are these copepods of some sort..

slug... could not make it to the fish store... sitting here watching this thing..... on occasion this thing will start flipping around and bucking like a wild bull..... what ever it is... it is very active... lots of moving around.. non stop..

Man I had no idea there were so many of everything.... Nope.. did not see it... I looked thru most of those pages... now I am confused is it a worm, or a slug, or something else?

I think I would take the Marine Biologist's suggestion as a real good possibility.

gettingclose... I think itis a Frondosus bushy backed nudibranch.... and I also think I found a sack of eggs... I pluck them out as well...

well we will see ifhe is still alive tomorrow... Very little info on this one.. everything I read is like a copy & paste.. same thing... almost word for word... some say great addition to a reef tank... I am questionable .. put him back in the tank and let him get lost in the rock.. or just kill it.... Hate to kill it..... Oh man... what to do....anybody want it?

 

[Captinshinyside]

Put him in your sump and post the pic and all the info you can find on Reef central. Alot more traffic and alot of realy good info there. Someone will know what he is and if he is safe. I hate to kill anything if i dont know if its good or bad. Just seems wrong to me also. Good luck and keep us posted.

I took him to global leader... he said he would take care of him. (dispose of him)....... he said he would not be good for the tank... don't chance it... thanks everyone...
