What are pods? Or feeding a mandarin question

[madison133]

Newbie question...humour me.

I'm looking at getting a psychodelic mandarin and keep reading that they like pods. I'm not clear what pods are? My other fish, flame angel, and two clowns eat formula one and frozen brine shrimp.

stats - 50 gal tank, compac light 96, 85lbs live rock, mushrooms, frogspawn, button polyps, etc. and a clean up crew.

One other thing..what is the toadstool doing at night when it sends out a thing that looks like a spider web over to the live rock.

thanks for any info
Linda
