Yeah, our tank requires nothing except the addition of occasionally heated distilled water and flake fish food.
The biowheel has to be the greatest possible thing ever invented for casual freshwater tank owners.
We have nothing in there but statuary and the pleco just picks up any leftovers.
Tank chemistry has been so constant we quit buying test kits years back and the wheel dumps a ton of oxygen into the water, so we can use distilled just pouring over the top instead of an aerator from the bottom.
Hardly ever have to change the filter with so few fish, and they're about as active as you'd expect several year old comfortable schooling freshwater fish to be.
What have you done with regards to freshwater fish before? One of our major concerns has been the chlorine in the tap water, so even just rinsing off a charcoal filter can be problematic.
We have one of these in the back and never clean the wheel (told not to, messes with the stability of the tank):

I'd love to get into more stuff with fish but I'm far into easymode just due to lack of time.
