i think i want to divide my 5g to 2 2.5 g

I am always seeing these poor little bettas needing rescuing but I can't buy anymore tanks...I see a lot of members here who keep their bettas in 2.5 g and I was thinking of dividing the tank so I could house another one.

 

They don't make dividers for 5 gallon tanks so you'd have to make your own. I'm not sure how that would work as far as a heater goes though as it would overheat one side. Maybe you could just get a 2.5 gallon tank and get a Betta for it? They are so compact it can fit on a desk.

 

yes I guess that is what I will do

 

Getting a 2.5 would be better than dividing a 5. When you divide a tank it tends to create two more vertical areas, so there is less horizontal swimming space in half a 5gal than there is in a 2.5 tank. Am I making sense?

Oh, and if you get a 2.5 I would recommend a female Betta. Some males get quite big and would feel cramped without at least 5 gals.

 

i'd agree with getting 2.5g tanks rather than dividing a 5g.. because of the divider issue and on tall 5 gallon hex tanks, it would leave the bettas with just these slender tall swimming areas.. is your 5 gallon a hex or a rectangular?

 

hex, phloxface has her male in a 2.5 though...and a lot of other members too.
yea I guess ill just but a 2.5 g

 

Frasier is still a baby so he's very tiny in the 2.5g. It's not out of the question to keep a male in a 2.5g but a female fits better. I will be moving Frasier to the 4 gallon tank as soon as I get the 5.5g for Niles. For now though he likes the 2.5g and has lots of room to swim.

 

yea, we have 3 2.5g tanks.. 2 have females and the 3rd has a male, but he's only in a tank that size because of his special needs with his swim bladder and he seems more comfortable in a smaller tank with 'ledges' we give him (his cave and silk plants) to rest on.. for a male a 3 or 4 gallon is probably minimum.. they can be in a 2.5g like phloxface said, but are mostly happier if they can have a little more room than a female.

 

I prefer to give Bettas as much space as possible. I had a betta in a 20 long and he was extremely active, cruising around the whole tank. 2.5 gallons is very small, even for a Betta, so I'd personally put in the smallest Betta you can get, which would be a female.
