Continuing on with this project. Dad decided on 2. Getting barrels, and getting 7x10 pond liner for each one. One will have either some killifish/livebearers, or a Dojo Loach or 2. Preferably the Dojo Loaches. I don't think they need a heater and can live outside without problems, but just want to run it through you. One barrel will have Hornwort, Dwarf Cattail, Red Root Floaters, a singular Mosaic Plant, Creeping Jenny, and on a small land part,a singular Oak Creeping Fig that can roll down the barrel or go wherever it wishes, and one other plant for me to find out. The second one will be simple: most likely Lillies, and/or Water Lettuce with Cambomba.
Dojo's would go in the one with Dwarf Cattail, and most likely a few ornamental fish such as a comet and 2 Fancy Goldfish would go in the one with lillies and/or water lettuce. Any thoughts on the plant stocking?
