that is a tough one considering how small ur tank is
you could go for 5 neon tetras
they might be uncomfortable though
a betta fish would look beautiful in there and they dont need any heating/filter/bubblers
a single goldfish
3-4 different types of guppy
you could add snails to any of those fish

Any one of the following options, you can mix & match:

3 Male Guppies

4-5 Neon Tetras

3 White Clouds

4 Otocinclus

7 Ghost Shrimp

1 Betta

1 Dwarf Gourami

3-4 Zebra Danio

4-5 Harlquin Rasbora

3 Black Neon Tetras

4-5 Silver Tip Tetras

2 Scissortail Rasboras

1 Angelfish

2 Small Cichlids

2 Chinese Algae Eaters

1 Siamese Flying Fox

4-5 Glowlight Tetras

1 Small Gold-fish

6 Cherry Shrimp

4-5 Galaxy Rasboras

4-5 Black Skirt Tetras

3 Upside down catfish

2 Buenos Aires Tetras

4-5 Cardinal Tetras

1 Blue Gourami

Any of these would do well in a 4 Gallon Tank.

1 Betta (Siamese Fighting Fish).

That’s it.

For a 4 gallon, effectively tall not long tank, that’s it. It’s a TINY volume of water that doesn’t provide any swimming space for fish like Tetras and Guppies.

edit: A Goldfish needs 20 gallons minimum, there’s no way it could fit in a 4 gallon! Neon Tetras are active shoaling fish that need 10-15 gallons long. And Guppies are very active fish that ideally also need 10 gallons plus, over 15 gallons for a breeding group.
