Tank size controversy- is 2.5 enough?

I was looking at 5 gallon tanks and was considering getting one. I wanted to divide it so I could have two bettas, but I've seen a lot of controversy about the minimum space for a betta. I was wondering, what do you think? Is 2.5g enough?

I personally don't like keeping bettas in less than 5 gallons each (this being said, I will be setting up a 3.6 and 3.9 gallon at some point), but I believe bettas can be happy in a 2.5 gallon. :)

Everyone has different opinions, and it depends on the individual betta sometimes, but personally I think 2.5 gallons is good for a betta. They're small fish and have quite a bit of space in a 2.5 gallon. As long as the water quality is kept up a betta can thrive in a 2.5 gallon. I have a betta in a 2.5 gallon and he seems to enjoy it. Hes very active. I always say bigger is better when it comes to fish but I do think a 2.5 gallon definitely works for these fish.

Water quality is more important than anything. And a 5 gallon tank split for 2 can be just lovely. But maybe I am a bit biased, since I keep my 2 boys that way. What you don't want to do is start by giving one fish 5 gallons all to himself and then split the tank. Start it out as split, or get a different tank for a second fish.



This is also not true for giant bettas, of course, they would need at least 5 gallons, but probably closer to 10 gallons all to themselves!

For regular male bettas 2.5 is fine. It all depends on the space you have, the time you want to put into cleaning it, what filter you want etc. . Betta are versatile and they usually seem content in the end anyway. Given their history in the cup ;)

I think a 5 gallon divided would be fine but I would cycle it first, otherwise 100% water changes every week will be a hassle.

I have done 1g, 1.5g, 2.65g and a divided 5 gal tank with no issues. Twitch and Freddy have been in all of them minus the 2.65g. My guys do great in any size, but my upkeep changes with the tanks. Mine are not cycled as well. Right now I have a 10g with 3 males divided, they think they hit paradise (upgraded from 1.5g tanks). Bigger is always better, but 2.5g is by no means abuse :)

Haha controversy oh darn =D I have everything from 1 gallon to 20 gallons and soon a 29 gallon... It depends on the care. I dislike having to clean the one gallons so often but I still do it. If I could, I'd have 3 gallons or more per betta.
