Is 20 Gal adequate for my ideal fish list?

So get males, they are more colourful.

That’s the plan Thank you!

You can have both schools of tetras but without guppies, or one school of tetras with guppies.

Guppies would be best for this tank size.

Guppies would be best for this tank size.

Not only gups, OPs fish should be okay in their tank but preferably bigger tank for their stock.
