Please help ID

[Vitaly S]

Hello,

I have couple creatures that I need help to ID.

First one:
I have these appear on glass, usually a within a day after I clear the glass. I think this might be some sort of flat worm. Is this bad one? How would I go about removing them if they are bad?

Second:
Based on a sticky, I think these might be pineapple sponges. They appear on my rock-work in the shaded areas, and in my sump. I watched them for a few minutes to see if they move, but they are stationary. Here are some pictures:

Thank you for the help!

First picture is Waminoa Sp. Or more commonly referred to as Pumpkin Flatworms. You'll want to remove them as they can smother coral. Second and third picture is pineapple sponges. They're harmless filter feeders.

I see these only on glass and just scrub them with my glass cleaner. Is this enough? Is there a fish that would eat them?

Certain wrasse will eat flatworms. 6 line is the most common.

Green spot mandarins, Melanarus and yellow coris also eat flat worms.

Don't buy 6 line wrasse bad idea. Goggle online and you will see what I mean.

Yep, just looked up, seems they can get aggressive. Is there any other fish you would recommend?

I've also ordered flat worm exit, not sure if it will work, but will try...
