Harmless filter feeders

No, leave them be. They filter feed and are harmless

They are jelly like are they dangerous?

nope, they can bother zoas a little, but are harmless, have no toxin, and just float around, find a home, and suck algae from the current

in fact, they can help make your water slightly more clean

Brilliant thank you so much for your help

you can scrape them off with no trouble and move them if you want to see them in a specific spot, but dont take them out of the water as its really bad for them

scraping them off is a good way to get them to spread, they reproduce asexually and can regrow from a tiny piece

yeah, sponges are cool, you can move the scraping somewhere else, without removing the sponge fully.
