Blob ID Please

[1337]

I found a couple of these in my tank and have no idea what they are. Good or bad?

When the little blob is floating around it is flat like a pancake, and then blobs itself up when you mess with it. Its small, maybe slightly larger than a pencil head.

Thanks!

Polyclad flatworm vs Sea Slug. Very cool in my book, but best removed. Can be predatory to snail, clams and I have heard some corals.

Look like a baby polyclad flatworm =(

Bad news if you have clams...

Welp that one went down the drain. This is in my 14G that crashed a while back so it has nothing but zooa's and an SPS that wont thrive in my other tank under T5's. I was WONDERING why all my snails were dying. I know I saw 2 of these together but only grabbed one, now I'm on the hunt.

Maybe the six line will eat them. ;/

No clams thank god.

Just an update. Bored at work and spent some hours trying to find pictures of this specific polyclad. Finally found someone asking the same question on nano reef with a pic of this same species as an adult. Same pattern just darker colored. Or maybe not starving. Snail killer for sure. So now I know why all my snails keep mysteriously disappearing.

that first pic in the bowl looks like its just a piece of one to me

Maybe the six line will eat them. ;/

I think a 6-line eating one of these things would be like you trying to suck down a towel....or blanket. lol
