The heck is this thing?

[CrazyEyes]

Sorry for the bad pic but, anyone have an idea what this thing is?

 

[Nwest]

Looks to be some type of Nudibranch. Not sure of its species though.

 

[janes_mw]

did that come from my tank!?

 

[CrazyEyes]

No mike, I saw it when I got home before adding anything.

 

[oblio]

Absolutely a nudabranch. So are good some not so much.

 

[CuzzA]

Looks like a montipora eating nudi. They're usually white.

 

[CrazyEyes]

Yeah I think that's what it is, sucks because I really think its cool looking. Will these thing eat other SPS like acros, zoas and LPS?

 

[CuzzA]

Not if it's a monti eating nudi. The fact that it's crusing your glass suggests that whatever it eats isn't in your tank as they normally don't leave the dinner table.

 

[CrazyEyes]

Decided to just remove it, makes me want a reef safe nudi though

 

[MrHarvard]

Nudi for sure and that's why I passed on those maricultures we talked about.

 

[ReyR]

Looks like the kind that eats aiptasia

Been considering these for my tank to be honest.
