Sponge or...

Schnizzle · Jan 10, 2020

I’m assuming this is a form of branching sponge. I’ve been watching it grow for a while now. When I first spotted it in my sump it was three branches about one inch each. Now it occupies a space the size of a cantaloupe. I’m hoping someone has a definitive ID or a source I can use to educate myself. I’m fascinated by the finer details of everything in our tanks. It’s pure white in color, it’s just lit up by Kessil.

+1 for sponge

Pink Sponge | Melev's Reef

This type of sponge is invasive in nature, so you may need to trim it to keep it in check. It sends out thin tendrils as it spreads into neighboring corals. Reef-safe-ish.
