Feel so bad for Fighting Fish - terrarium? Hanging fish tank - could easily be made with a banana hanger and a ceiling light set from a home improvement store; would be fun as a snow globe or terrarium, too.
One Pot, Two Lives The fish eats and ‘wastes out’ its lunch, the plant feeds on its nutrients. The plant eats some water and filters it down so it is clean for the fish. Now the challenge is can I keep both a house plant AND a fish alive?
