how much light for mushrooms?

[mark]

Trying to get some room for some new zoos so want a rock full of mushrooms out of the display so placed in my 20g fuge.

Wondering if a 23W SCF (lite 24/7) would be enough to keep them going?

yeah i think it would keep them going fine. you probably won't get much growth out of them, but they'll live as long as you keep water quality up. you'll probably get a hell of an algae growth going thuogh.
