Habitat - Indoor :: water changes

i have a 4 inch res in 26 gallons of water....how often should i do a water change and how much each time

[marisa]

What kind of filter to you have and how many gallons does your tank hold? 26 gallons of water doesn't sound like that much...

A 4-inch RES can produce a lot of poop. Do you feed in the tank? Are there other creatures in it?
