Thanks, i'm sure you guys know, since you feed them this stuff! First- Dandelions. They like them, but what kind to feed them? Yellow, white and puffy, dried, the root, the whole thing... i don't want to be careless and just throw some in there. Rice- Brown, right? Cooked or uncooked? where can i get this? Also, i hear people grow some foods in their tanks. Is there any foods i can grow (they're PPs) in a sand-coconut soil substrate?
