Looking at my rear chambers...

[hllb]

I have my first pineapple sponge!

and a lone aiptasia on my return pump. Should I kill that thing? I’ve only had 1 in my display and my peppermint shrimp ate that immediately.

I have a few in my sump along with a whole bunch of small featherdusters. I leave them and let them filter the water.
