Those are good all good critters. Have you had any spikes like nitrates or ammonia

Brittle starfish? Or bristle worm? If you have a hybrid creature of the 2 of them I want some. I bet they'd be great at taking care of detritus.[emoji6]

I meant to say brittle

The sponges will pull silicates out of the water and the brittle stars are great detritivores.
