Description: I have a 10 gallon with my Betta (Monsieur Lumiere) in it. It has a top fin filter and a small heater (not sure of the wattage).
I also have a 50 gallon (36"x18"x18") in which I have sword tails, tiger barbs and Lyretails. It has a Fluval 4 plus Filter and an Avant heater.
Advice: Don't get a Betta they're boring
