It doesn’t need to be fancy. I use my original 14 gallon biocube from when I originally started back in 2010. If I didn’t have it then a $10 10 gallon from petco, cheap Wal-Mart pre set heater, HOB filter, and pvc fittings gets what you need.Sounds like I have to to get a qt tank set up. Heck I've already put upwards of $600 in this tank and fish. I guess if I want living fish, spend some $ on a qt tank. Thanks!
