Flatworms on new mushroom

[entranced]

What are these? Are they bad?
They came in that particular rhodactis, havent seen then on the other ones i got the same day

For clarification, saw one crawling on my glass and they are indeed pink, not really transparent. The one on the glass went swimming, so they do swim.

Is it ok to dip the mushroom in FW to try and get them out or maybe on a drop of flatworm exit? besides the one on the glass i havent seen them leaving that particular piece

they are flatworms, you don't want them in the tank but if one went swimming, you do in fact have them in the tank.

That one went straight to the toilet, should i dip the rhodactis in freshwater to take the rest out?
