Glass slug or ?

[BubblesandSqueak]

Found a couple things in the filter today. Bristle worms and glass sea slug or something else?
Opaque with pink dots. Looked like a pink hotdog skin outside of water but in water became opaque with pink freckles. Tampa Bay source. Fleshy limpet?

That's a flatworm - not a keeper.

top pictures: polyclad flatworm - not reef safe

Bit transparent for your run of the mill bristle worm. But yes they do look like a sea slug of some kind and a bristle worm. There's so many species of these flat worms out there I doubt you'll get an ID, don't keep it. (Flatworms and sea slugs aren't actually the same thing but sure look alike)

looks a lot like Pseudostylochus obscurus - I'm not sure about their distribution and if they are found in Florida.
