Noticed movement in murky water in small vase amid pile of stuff on client’s kitchen—betta that no one wanted. So I took him home. Took a couple of days to set him up in a tank—3 gallons. He totally changed color overnight. After a lot of trial and error—biggest mistake was fake plants—now have real ones. For a while he only used half the tank. That was May. He’s gotten much larger. I feel he needs a bigger tank. Any recommendations on 5 gallon tanks, or tanks in general? He’s on the kitchen table—he really loves the attention and interaction. (And the windows—no direct light. I know he watches stuff because he got all excited when I stood outside the window.)

Hello and welcome to the forum!
He's a gorgeous boy, does he have a name?

I've always been a fan of the rectangle 5gals. They can be easily found at PetSmart.
For durability, I've got two TopFin 5gals that have lasted me several years with no issues. Just sharing, if you're concerned about how long they last.

Beyond that, size is up to you. If you want bigger, go for it!
I'm also going to disagree with Betta Nerd for a moment. There's a lot of different opinions on what size Bettas should be in minimum, with the common mentality being 2.5gals. As there's no scientific proof backing up what size is best for Bettas, 2.5gal minimum is still expressed as an opinion.

Though, if anyone happens to have unbiased, scientific proof on Bettas needing a certain tank size, I'd be fascinated to hear it! And please correct me too.

Anyways. Size is totally up to what you can fit, afford, and prefer! And welcome again!

Fishy Boy. Everyone always calls fish Fishy. So he’s Fishy Boy. And I swear he knows his name. My husband and I adore him. As one person said, they have the personality of a puppy. I have a cat that Fishy Boy really likes. When she lies in the table next to his tank, he lies on the bottom next to her.

I also don’t use the lights—I wouldn’t like being blasted with those bright lights. He has plenty of indirect natural light. So he has a pretty natural sleep cycle, other than the kitchen light and/or me doing dinner and maybe late evening tank maintenance. When the sun goes down he goes to sleep.
