Dividing a 20 Gallon Long

Pitluvs

They would have 3g each, but you have to take into account the space in inches. When dividing such a large tank, your better off with a little extra in gallons to achieve the inches you need per fish.

Like a 10g tank... if you want to give a fish 1g each, you would need to divide it 10 ways. They would never be able to turn around! lol

3gal is fine, but the space won't be.

Personally, I would divide it into 4 and keep a little room on each side for your pumps so Bettas can't get to them.

I agree with Pitluvs. 5 1/3" of swim space isn't alot of space to turn around. That would be pretty cramped. You *could* do it if you needed to, but I would rather give the bettas a little bit more space to swim, not cramped up next to a filter etc. In theory it works, though.

+1 the less like a prison our tanks are to our fish the better. I'm not a betta keeper but don't female bettas get along? Maybe you can use a larger space for a female sorority.

Female bettas can get along, but they will also fight in conditions that aren't proper for a sorority. If they are kept properly, this is a great experience!

@stevenjohn21 This is a great and rewarding route, just make sure that you do research. You may want to swing over to TFK's betta forum (log in with your TFK username and password) and post a topic there. They need a certain amout of female bettas (too few can cause many problems), and tons of hiding spots. Start a thread there and I am sure that they can help you.

Thank you, i just started a thread over there. I have heard not to keep males and females in the same body of water even if it is divided and blinded, why is this ?

Hmm...I don't know. I have always heard that it is Ok to keep a male and a female in a divided tank. I have read here and in other places that if you are dividing a tank 3 ways with clear (see-through) dividers, that it is best to have the males on either side and a female in the middle so that the male won't see each other.

Oddly enough, there are afew people on BettaFish that keep males free-roaming with the females, but I would never recomend that to anyone. Usually that starts out with a young PK/PKHM or DT/SD being mistaken as a female. There is no concrete method, and it usually doesn't end well. So do not attemp that!

But, I don't know. Were they talking about that on BettaFish? Maybe someone else can shine some light on the theory.
