20 gallon Long aquarium

[bobo2020]

I’m getting a 20 gallon long aquarium. Here’s what I want:
A pair of dwarf gouramis
Either 8-10 neon or rummy nose tetras
6-8 cherry barbs
4-6 albino Cory cats
1 mystery snail

Is this too many fish? If so what should I take out. Also, should I do neon tetras or rummy nose tetras?

Try this.......Aquavisor

I would recommend only 1 dwarf gourami, because 2 males will fight and it's also almost impossible to get a female. Everything else seems reasonable to me. Aquavisor is definitely a good tool to play around with for stocking.

Ok thank you. But should I do neons or rummy noses?

[Laser]

Although I'm a fan of the neon tetra's colors, I can't recommend them anymore. They used to be a somewhat resilient fish, but I feel that over-breeding in the aquarium trade has made them weak. In short they are a very sensitive fish and are difficult to keep alive.

Go with Cardinal Tetras. They don't have the problems neons do and better coloring IMO.

I considered them but they cost more

Just to be contrary, I've had good experiences with neons. It seems to me that if you get them past a two-week "break in"/quarantine period, you'll do well. Obviously, others have had different experiences.

Regarding Rummynoses, they're very active swimmers and (just my opinion) do better in a tank longer than a 20-long.
