haha i wouldnt do that... I believe in trusting each betta owner to know what is best for their fish, and if i wasnt so lucky my fish would still be in smaller tanks and they would be perfectly happy :)
Exactly! Every fish is different. So are their owners
My king/giant lives in a 10 g with a few friends, I do not think there is a diffrence between a king or a giant be it mine was sold as a king and people say they are smaller than a giant he is over 3 inches he is a an awesome fish fun to watch, very active
It's all up to you. All of my males are in divided tanks and have 2.5 gallons each (don't jump on me. I know what I'm doing.). If you can provide five gallons that's great. A giant would like 10 gallons, so would a normal betta. A giant would be fine in a five gallon though.
No one should jump on you for that! (not that anyone has yet!) I have my Thyeo in a 5 gallon with 2 guppies and a snail and people said I was doing it wrong. So power to you for knowing your fish! :)
a giant would be fine in a 5 gallon, but would be even better in a 10. plus if he's not too aggressive, you might just have room for a few tankmates (a trio of not-too-bright platies could be a good option)
