As. If as you can IMO because you will want to upgrade soon lol

but seriously the bigger the tank the easier to take care of in the aspect of water parameters. They won’t get out of control as fast because of the water dilution.

Since your question remains unanswered...
Yes, a 20gallon should be fine, particularly if it is a 20gal long (as opposed to a 20g high).
There are many kinds of tetras, some larger, some smaller, some quite boisterous, some calm and chill. It matters a lot. You may not want larger tetras in a 20g.
You should plan on weekly (minimum) water changes, and to go make sure of not adding fish until your tank is cycled.
Something like silver-tip tetras, lemon tetras or neons may be good for you. Good luck!

For a starter tank, I really like standard 29gal. It's the taller version of a 20gal long.

Keep in mind Petco is running their $1/gal sale until the end of January on Aqueon tanks. They say it applies to 10, 20, 29, but 40 breeders, 55's and 75's are discounted as well.

thank you so much !!
What everyone said is 100% accurate, one thing I’ll add is after 35 years of fish keeping, trust me , get the biggest tank that you can. If you have room for a 40, but get the 20 , you’re almost certainly going to end up getting the 40 later anyway.

"For a starter tank, I really like standard 29gal. It's the taller version of a 20gal long."

I think there is a typo here, otherwise it is not correct. A standard 29g is NOT the taller version of a 20g long. There are 20g long and 20g tall, the latter taller but shorter (length). And then, there are standard 29g tanks, which obviously hold a slightly larger volume. And then, of course there are 30 long tanks as well.
Let's also not forget that all those volumes are "nominal volume", not the actual volume, and are assessed without substratum, filled to the rim, and generally are quite a bit higher than the volume an aquarist may be able to accomplish in each tank.
