Sponge Help

[FishyDP]

I just moved this zoa colony from another tank to my new display, and noticed this large and thick purple sponge growing on it. It is starting to take over the zoa rock. Aside from manual removal, are there any other options for removing it? Ideally I would like to get some type of critter that feeds on it. Also, wondering what type of issues this type of sponge can lead to, and just additional general info. about it. Thank you.

Many of us consider the sponges a good guy. In a small way they help filter your water.
I added a bunch to my tank.
The different colors can be hard to find.
I don't have any purple. Just blue, red/pink, yellow and fuzzy white.

You can scrape it off if you don't like it and send it to me! [emoji846]

I like them and I guess they could potentially smother something they cover. I've always tried to keep them around, even changing aquascape to make sure they don't get covered up.

Okay, so it sounds like they are generally good to have. I do like having filter feeders in my tank. Only concern is it smothering the zoa colony. I guess I could trim it back away from the polyps.

They do look nice, you have some good variety there Norfolk.
