Ideas for stocking for a 20 gallon

[PattysAquatics]

I’m going to be setting up a 20 gallon and need some ideas of what to stock it with. I already have a community, swordtail, guppy and pea puffer tanks and don’t know what to stock it with. Please help

I would go with a group of 10 x-ray tetras 1 bristlenose pleco  1 honey gourami and either Ramshorn snails or nerite snails

Long or high? 

For a long, maybe a shell dweller species tank. Multis, gold Occelatus, or one of their cousins. 

For a tall, @Colu has a good suggestion. id maybe add a small school of a smaller corydoras species or kuhli loaches. 

In either tank, a neocaridina shrimp tank would be neat as well. Just pick your favorite color.

cherry shrimp, and chili rasboras. with maybe a clown pleco or pandagarra.
