Fish tanks, continued

My musing of the day was about getting my aquaponic garden up and going. Found a “local” fish die I want to check out, started making a list of what I need beyond a tank, but. I’m not doing this outdoors. I’m not eating my pets. I’m not going stupid small, nor super big.
I think 20 gallons sounds good. Freshwater, because I’m not eating seaweed this year. I want pretty. I want friendly. I think I just need to go to the aquarium store. Maybe the thing is, based on how I’m not dealing with eating the fish, just maximize my fish. Start with a handful of tetras. Risky add more until the tank his a maximized homeostasis. I think I’ll talk to the wife about going there in the next few days. Their website says they’re open on New Year’s day. That would be an auspicious beginning to the year.
But yeah. Most of the documentation on aquaponics is all about factory farming tilapia or done in white plastic tubs. I want to see my friends.
