I appreciate all the replies and compliments. It's cool that you guys enjoy it as well. This hobby is really enjoyable for me and also therapeutic,
Chuck- Cleaning isn't bad, I do three water changes (25%-45% of volume) a week by siphoning the gravel. They are "dirty" fish meaning there is lots of dookie. I also use a razor blade to scrape the glass to get rid of algae.
Curtis- I have about 35 fish in there. The Rio's are fun. I should note that I caught them October '15 at about 1-2" in the Colorado with a dip net. They pretty much have staked their claim in each hole of the cinder block. They get along with each other and none of the other fish mess with them. They are very calm, almost methodical, definitely seems to be the smartest fish.
Jamie- I will have fish in this aquarium live longer since most were caught as babies. My other aquarium is stocked with adult fish I catch. I'm happy getting 3yrs out of them. Right now my load is pretty full, I'll only make room for a rare or unique fish.
DR- I use pumps to break the surface tension for gas exchange, this takes the place of aerators for me.
Robert- if you are talking about the 3rd to last pic, thats a Red Shiner.
Don't worry about the mule, just load the cart
