what is this in my son's tank?

[Robertchrisroph]

It hangs out on the side of I think is his anamone. It moves around. Lol

 

[Justiful]

Sea slug, I think. But I am no expert. But if it moves around like a snail, it is likely a sea slug. Your talking about the violet thing below the anemone right?

 

[Robertchrisroph]

Yes

Hard to tell from the pick but it could be a Chiton. Does it look anything like this? If it is a snail or type of gastropod, tenticles/feelers or some sort of sensory organ should be visible.

 

[Robertchrisroph]

Yes. Without the ridges

 

[Amit Kumar]

eat it!

 

[reefbeard]

A Fleshy Limpet perhaps?

 

[Justiful]

I think it is a Chromodorididae Sea slug. I think I see a trim of a slightly different color than the body, and it has the ridges around the outside of it. Can we get another pic? Maybe different lighting on it?

 

[Robertchrisroph]

Looks mybe sea slug from us looking up pics and my son says when it was on glass it had antenna lol

 

[Robertchrisroph]

It moved to the back of the anamone trunk can't see anymore. Will try later

[reefbeard]

If no shell is present under the flesh you may be dealing with a flat worm which do resemble sea slugs. Any tissue damage to that coral it is hanging on?

 

[DeniseAndy]

I would have guessed flatworm. How big is it? Redish in color?

 

[rajkovich207]

Flatworm of some sort would be my guess, also that's not an anemone it's a torch btw

 

[DeniseAndy]

I was going to mention that too. If it is bothering your torch or anything else, I would do a treatment of Flatworm exit. Follow directions!!! Very important.

 

[Tahoe61]

Yup Polyclad flatworm remove, he might indeed be munching on the Euphyllia.

 

[reefbeard]

Some sort of predatory polyclad flatworm. A positive id may be possible with better pics. Either way I would remove asap.

 

[Robertchrisroph]

Thank you. Yea no damage that I can see. It's mybe 1/2 inch. No red just whitish around rim and grayish

 

[Robertchrisroph]

How should it be removed? P k ease and thank you

 

[Tahoe61]

When you see it again and you will most likely see it near the Euphyllia move fast and remove the entire piece and shake the worm off in FW, or salt. Your chances are better at night. They move really fast but once you get them out of the water game over. Try not to dip the polyp head of the coral in FW if possible.
