It's a good idea to over-plumb. That is a big part of keeping the maintenance time low. That and not putting too many fish in the tank. I run a filter and heater meant for 60 gal tanks in my 30 gal.
I still have the pet store gravel (kind of a brown natural) in my tank, plus some of the rocks I have collected over the yrs on top of the substrate. I boiled the rocks and then let them dry in the sun. Never had a problem with them.
I don't test water quality anymore. Kinda like once you get to a certain level of comfort, with cigars, you don't really care if you have a hygrometer or not. The only thing I add to the aquarium water is 1.5 tblsp of aquarium salt bout once a month, during a water change.
I have a weird mix of fish at the moment as I am in between set ups. For many years I had a Silver Dollar tank, and now I'm in the process of making a native tank. I figured that since I went native, so should the tank.
I have 1 Silver Dollar (9 yrs old), 2 Green Cory Catfish (5 yrs old) a Bluegill, and a big crawfish. Crawfish lives in a rock cave, does a good job cleaning up the bottom of the tank. They all get along too. Not what I expected.
Next spring, if/when I have time I'm going to try and trap another Bluegill fry or maybe a Smallmouth Bass. There are several different species of fish in my creek. Fished for and caught some decent Smallies and I've even seen Brook Trout in there... Ultimately, once they grow out, I'm going to upgrade to a 75 gallon tank.
