Male betta in 20G high community tank?

The tank has 4 ghost shrimp
1 platy
6 neon tetras
6 harlequins
4 albino corys

I also have a 50G aquaclear filter. How will lets say a half moon do?

It really depends on the betta. Mine will not tolerate any tankmates other than snails--he killed seven tetras in two days when I tried. :-/

Yup, it might work beautifully, or it might be a disaster. There's really only one way to find out....

I would only try it if you have a backup plan for the betta.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

Betta has to be docile enough to not harass your other fish too much but also has to be aggressive enough to compete for food with those fast moving fish.

Everything happens for a reason, but the reason isn't always good.

Yeah, every betta is different when it comes to temperament, and how it acts in a store cup may not reflect its true personality when it gets into a tank. For example, when I first picked up Romeo, he was extremely active in the cup, flaring at the other bettas and swimming around. In the community tank, he's very peaceful with the cories, although I have seen him flare and chase on occasion. It's usually pretty short-lived as cories are far too fast and have a lot of places to hide.

My other two halfmoons could NEVER go in a community tank. They were docile in their cups, but in the divided tank, my word, they're active all the time and pretty darn aggressive.

Just be sure you have a backup plan in case the betta doesn't work out in the community tank. :) Good luck!

The bettas:
Romeo - HM male | Tzekel-Kan - DTHM male | Nemo - CT(?) male | Akio - DTHMPK male | Ares - Delta male | Diablo - SD male | Nameless - VT male | Nameless - DT female
The others:
The Fab Five: Green cory catfish | Maximus: Golden mystery snail | Ichabod & Rosa: African dwarf frogs
Swim in peace, Gaston.
