Things To Do Before Buying Shrimp

Will there be just the shrimp in the tank? If that's all there will be, you don't need to buy any equipment to feed them.
I feed my shrimps on crushed Hikari Shrimp Cuisine, though they also eat fish food that add for the fish. The crushed shrimp and fish pellets are quite small and even juvenile shrimp can get hold of them to eat them. I even have shrimps walking upside down on the surface to grab any flakes the fish don't get.

Do you have any plants, real or fake? Both with grow micro-organisms on them which the shrimps will also eat. Plants also make good hiding places for shrimps to feel safe in when they moult.
