[seth16]

I found this thing in my tank last night and immediately put it a seperate container in the tank, i wna to find out whaqt it is before releasing it back in there, idk what it is or where it came from (...) but i wnat to know what it is, it is like a slug, looks and moves like one, but has like tentacles on its back, like an anemone...any help???

It's a fuzzy slug.
Never seen anything like that before.

It kinda looks like Phidiana hiltoni but hard to say from the pics... Does it have red/brown & yellow in it?

You can find a variety of pics on Google Images...

If it helps your search its SOME kind of nudibranch for sure... there are many different kinds ranging from harmless to "going to eat your reef ASAP" so best of luck on the ID I hope its a safe one (not many are : ( )

 

[seth16]

I checked the pics, and yes, it is the Phidiana hiltoni

it looks more like this one...

or this one

are these ones ok for a reef? what will they harm/ help if i put it in there, and are there any outstanding marks to identify if this particular species is a nuisance or not?

It looks alot like a zoanthid eating nudibranch~Aeolid

How are your zoos looking? they can seem pretty munched on from these guys. Freshwater dips and TMPCC really help to eradicate these guys.

Gotta take the zoo colony and swish it vigorously in the mix (can let it soak for a few minutes before hand) and any potential zoo eating nudis should come off

 

[waterfaller1]

It could also be another type of aeolid...berghia nudibranch..

I always say "when in doubt take it out."

 

[seth16]

Like i said before,. it is not "in" my tank yet, i will just thrown it in my 5gal (my tank for things i dont want in my coral tank ( monster hawaiin Red Anemones, Huge crabs...lol))

 

[seth16]

ok, it is definately a Berghia...so does that mean it is ok to keep in my tank, if it eats aptasia, i want it...lol

 

[sttaylor]

I do not think it is a berghia. The markings on the head are not right and the body of yours is very dark. I would be very careful with it.

Here is a berghia pic from my tank:

either that or a Hiltoni

Looks like a monti eating nudibranch. I got some exactly like that on one of the superman in the shipment. I killed them all by dipping in strong Iodine solution.
