How big should a betta tank be?

[FireKidomaru]

I was wondering how big betta fish tanks should be. I have two tanks that are about 2 gallons each. They used to have bettas in them but they both passed away. I was planning on getting two more but I wanna make sure that the tank is acceptable. thanks for all the help

Honestly it pretty much depends on how often you want to clean them. 2g is perfectly acceptable as long as you are changing the water about twice a week or every 5 days.

I usually cleaned it every two weeks. By old bettas loved them. They died because i tryed a different chemical in their tanks.

Every two weeks??? Hmmm.... not nearly enough. I clean my 2g s twice a week. Ah, that reminds me, I need to go do that now! :P

I'd say a minimum of 2 gallons.

A minimum of 2 gallons cleaned at LEAST twice a week like kelly said if not more.

Yeah, I'd say at least 2 gallons. I clean my 2.5 gallon twice a week. One 50% and one 100% change.

Minimum 2.5 gallons.
