Weird creature

So I came home after work and do my inspection on all my tanks and noticed this thing on my glass crawling. I swear it looks like plankton from sponge bob. I dunno what it is. Any ideas? Sorry for the bad pic .

Nudibranch...what colors did it have?

Some can be bad.

Looks like a zoa eating nudi.....get it out and look for others.

+1 on RedfishBluefish... get it out

berghia possible? aiptasia eating one.

 

[mebo926]

It's was a pinkish blueish. Well when I see it next time I'm grabbing it out. If it eats zoas would answer why my blue ones are missing the fringe .

Looks like a Berghia Nudi. Just keep an eye on your zoas if you have any. Berghias are nice little guys.

looks like berghia nudi to me

This is the thing, there are thousands of Nudi types, the basic physical characteristics of the Aeolidioidae family are seen by zonathid eaters, aiptasia eaters, coral eaters.....Yes it does look like similar to a Berghia Nudi, but it also looks just like types that eat Sarcophyton and Xenia, it looks like what it eats. The likely hood that it originated/hitch-hiked in is more probable than the OP getting lucky and a Berghia Nudi just happened to hitch-hike in. If you have a coral where the polyp head and tentacles look similar to the Nudibranch than I would remove the invert.

This is exactly spot on.:thumb:

Free berghia? too good to be true. I would kill it.

Most likely it's a zoa eater. I've had them before. They are hard to see in the zoas themselves because they actually turn the same color as the zoas they are eating. Use a turkey baster or something else to get your zoas to close. Then you should be able to see between the stalks. The nudis can't close up like the zoas so they will be easier to spot. Check for eggs on the stalks as well. You don't want a major outbreak of these guys.
