An inside my empty powerhead filter adapter. Can someone please help me out if this description is enough to describe what I might have growing.

    they do fairly resemble those sponges but 1 do sponges just grow and 2 they kinda look like they kind of have small fan like heads kinda like fan worms but not really pertruding like fans worms.Also are they something to worry about

    What I'm thinking about are commonly referred to as "pineapple sponges" because they resemble the fruit. Is that the case with your sponges? If that's what you've got, then they're completely harmless.

    Yup, pineapple sponges. Their numbers will reduce eventually though as they run out of particulate matter to eat....unless you're feeding a lot of phytoplankton that is :)

    You really don't have to eliminate them. If anything, they'll help filter your water. They tend to grow in the lower lit areas of your tank so they shouldn't become an eyesore.

    They usually come in on live rock. I've had them come in on the rock that corals are attached to as well.
