How is your fish doing? I like your tank. Yeah, it may be a touch small for what we're being told, but I always thought Bettas should be kept in small areas. At least your tank is bigger than my bowl (but I am planning to move my Fiji-Foo to our old 10-gal. tank today).
BTW, I love "Beta Byte". Is that still the name, or did you change it? I think it's a cute name--and a very handsome little guy! :) Fiji-Foo is just a sort of teal blue/green (but a little on the drab side--though maybe that's because I've always had flashy fish! ;P)
