DIY low maintenance setup
I got a gift of an Ecosphere (a sealed glass sphere) that is kind of fun but I would like to build a slightly bigger setup and with more attractive fish like guppies or something. Searching youtube and the web did not turn up much that was appealing. Does anyone know of a way to make a sealed or very low maintenance tank with real fish? I don't want to have to keep changing the water, cleaning the tank, dealing with filters, etc. I saw one setup with plants above the tank and the water flows thru that, but it seemed a bit too complicated.
