Recently my friend, Toby, gave me a 2.5 gallon tank. Thought I'd put it to good use. Fauna and flora, some fish and nice lighting would sit well in the living room. He gave me some duckweed (floating plant) too. My lampeye killies love to swim just under them, darting about as tho they were playing catch. Myself and hubby also put flame moss in for the gobys to hide.
