5green, also, if you plan to get 3-4 bettas then get a bigger tank. 3 gallons won't be enough. I suggest a 10 to be safe.
Aris - Pure white HM! 5 gallon.
Pheonix - Red VT with blue highlights. 5 gallon
Died of dropsy.
2 bettas to fill my divided 10 gallon
Filling my 35 gallon tank, going to be a sorority once i get money for decorations...and fishies...and plants...and meds, filter, heater, light...
