Bugs in hob filter

[Kalin]

i dont have a picture cause I instantly cleaned it once I found them but they looked like white leach like bugs in my hob and skimmer. Does anyone know what they could be

Sounds like it could possibly be flatworms but that’s just a wild guess with no pic

Best picture I could find but they were all over my equipment when I came back from vacation

Are you sure they were bugs? Could be pineapple sponge

 

[Kalin]

Might be pineapple sponges sorry I’m still a little new to this. So are they good or bad?

 

[Fishy_mcfish]

They are harmless filter feeders

Ok thank you for the quick reply

100% pineapple sponges, completely harmless (unless in between coral like zoanthids, they could be hindered) & beneficial ^^
