Looks like some sort of filter feeder. I haven seen these in any of my tanks in years and forgot what they were. I don't remember them being bad.

i got them everywhere there is no light bunches of them. looks a bit like a cross between a sponge and a banicle.

YEP I googled pineapple sponge and that's what it is ...... any issues with these guys or just harmless filter feeders?

This, your good.

Pineapple sponges are indicative of good tank husbandry, which means you're doing something right

Yup, but they may grow over corals, which is unlikely, as they are often eaten by things, and grow in darker areas. No need for concern.

They seem to have multiplied and spread very quickly in the last month since I've started to add SELCON do my fish food. Bottle says its also a food for filter feeders and looks like it works lol.
