Tetras for 20 gallon species only tank? (not neon)

[ExHxW]

I want to try keeping tetras but I don’t want neon or cardinal ones. What are my best options?

Black Phantom Tetras are cool, they produce young that they don't eat, and they flirt with each other all the time which is great to watch.

Ember tetra, rummy nose tetra, black phantom tetra, glowlight tetra, serpae tetra just to name a few other smaller tetra. I'm a fan of rummy nose tetra myself though they're not as common where I'm at.

If you want a Tetra that will spawn then, Lemon Tetras, Black Phantom Tetras, Serpae Tetras, even Flame Tetras. If you don't care if they spawn, then Rummy Nose etc. etc.

A twenty gallon tank ? . I would go with ember tetras or one of the other very small species.

I have kept rummy nose but don’t think a 20 gallon is the right place to see them at their best.

Most Hyphessobrycon and Hemigrammus under 4cm length are suitable, as well as Axelrodia, Hasemania and smaller Nannostomus.
Petitella are out, they need a lot of swimming space and in a small tank their famous schooling behaviour deteriorates to a hectic mess. They make the tank stressful to watch and they deserve much more space. I personally would prefer 40-50 in a 150cm tank to 10 in a 60cm tank.

X-ray and golden x-ray tetra are my favorite! you some of each to make one school.

Black neons are cool, they are a totallly different species the neons.

I'd go for a good group of Glowlight Tetras, you could have a shoal of 12 - 15 of them if you've got decent filtration running, or you could go for a shoal of 15 - 20 Embers, either would be good especially if you go for a dark substrate & plant the tank well.

I have embers and really like them, and they love lots of plants to hide in.
