Would this work for a 20 gallon long?

I know ive been all over the place recently but would this work?
6 Praecox Rainbowfish
6 Albino Corydoras
Is this ok?

Thanks

Depends on your water hardness, although I wouldn’t count on it.

You would be able to keep small group of Dwarf Neon Rainbowfish in a 20g long, as far as space goes.

Depending on your water hardness, although very unlikely, you may also be able to keep a group of Corydoras.

Usually Rainbowfish like harder water, while Corydoras like softer water.

Unlike most rainbowfish, Melanotaenia praecox can live in water with hardness as low as 5 dH/90 ppm, though a bit harder would be better.

My water is very very hard. It leaves a white crust on the edge of my sink that we were told was mineral buildup. I chose the rainbows because of my harder water. Would a BN pleco work instead of cories?

I don’t get why you keep making new threads, and then changing it up. Can’t we just stick with one thread? All of this is getting confusing...

Sorry about that. Let’s continue on my old thread
