What can go in a cylinder 3 gal established tank?

[NorthPoleFish]

I have a cylinder 3 gal established tank. It has been up and running for over 2 years. All that I have in the tank right now are 2 snails and a small piece or hornwort. I would like to put a fish or something in that tank, but I don't know what kind of fish would do well in this tank. Would a beta do well? I've done some research on betas and there is confusing information out there on the minimum size. I've read anywhere from 2.5 gals to 5 gals as a minimum for a beta. So, based on that info, a 3 gal should be ok, but I don't know if it is an ideal size. If this tank set up isn't good for a beta fish, what kind of fish would be good to put in this tank?

Thanks for any advice you can give me.

Post pic of tank. What are the dimensions?

Cylindrical tanks are often tall and narrow which is why Fishmanic asked for the dimensions.

Swimming length is the most important dimension and I doubt that a 3 gallon tank has enough swimming length. Yes you will read that 2.5 gallons is suitable for bettas but a wide, shallow tank of at least 5 gallons is preferable.

Shrimp and snails. Maybe a badis badis or a really long finned betta.

That would do a nice cherry shrimp tank.

That's about it.

I recommend keeping what you have, if you are asking about something like my attached image. I received this years ago for a product review and in my opinion, is best used for a decoration. Which it is. I had it in a display case at a major airport advertising the scuba shop I worked at for many years. Now it is home and decorates a wall. Personally, I wouldn't change what you have. Snails and a plant tank. It is (in my opinion) cruel to put fish into an environment that will not provide them the best chance for a long, stressless life. It will be difficult to maintain a clean tank with quality water.

Sorry, the above image didn't post until now.

I have a 5 gallon cylinder with one fancy male platy, and a dozen cherry shrimp, and a few pest snails, I'm always catching out and disposing of, and I have a lot of plants... it's not a very good shape or size for keeping fish

Thank you for your advice and suggestions. I'm discovering in my research that this tank, while a good idea, doesn't work in the real world. I will do some researching into keeping shrimp, since I know nothing about shrimp. I might go that route or maybe upgrade the 3 gal to a 5 gal (which I do like the idea of).

The tank is 12 inches high and about 9 1/4 inches in diameter. So, a small tank. It was a Christmas gift for my son from his uncle many years ago.
