General fish keeping
Fish and plants that don’t need a heater
White Cloud Mountain Minnow (I’m planning to use this as the main schooling fish in my sub-tropical set up).
Peppered Corydora Catfish (Cory Cat) Unlike most of the other Cory Cats, the peppered variety is happier in cooler water.
Note: I researched a lot of different things that I pulled together on this site before decided to attempt a sub-tropical, planted, Walstad tank. But I’m leaving the rest of the links here in case someone else finds them useful. My first plan was to set up a ten gallon with a Betta and a few companions, but I’ve really fallen in love with the idea of schooling fish and creating the lowest tech set-up possible, to where I don’t even need a heater.
