Red/Yellow Knob encrusting sponge

[CD_Scapes]

Curious if anyone has kept/cared for the encrusting sponges from KP Aquatics? I was looking to add a few to my macroalgae-dominated tank, I can feed them reef nutrition Phyto and roti-feast as well as I have coralamino and spongexcel from Brightwell aquatics. Anything I should know about possible care? I will not touch them with my bare hands or expose them to air as much as possible.

I've had what looks like the red knob sponge on maricultured live rock do well but when I've acqured them seperate from live rock they haven't done well. Many sponges feed off DOC so the foods you listed aren't likely to work fo rthem.
