I have 30 bettas in either 10 gallon tanks divided in half or 20 gallon divided in thirds. Dividing the tanks has been good for me thus far, but I have soooooooooo many, I am killing myself. They all have filters, heaters, lights the works, but with this many tanks it takes me two days to do water changes. I see a 12 gallon tank with dimensions of 35.4x8.3x9.4 does this sound like a viable situation for me to cut down on so many different tanks? Really need help here and thank you in advance for all your expertise.
