Adding 4-5 cories? Good idea?

[Adam071409]

I've had my 20 gallon tall tank with a fluval U3 filter for about a year and a half now. It's my first tank I've ever owned. I have it stocked with a gold gourami, 5 neons, and 3 serpae tetras. They all get along wonderfully for the most part haha, but I'd like to add 4-5 cories to the mix because I want something new. Would this work with what I have in the tank currently or would there be too many fish?

Thank you so much

What do you have as substrate? Sand or gravel? If gravel, aslong as it smooth without jagged edge then yes. If its sharp in anyway it will damage their whiskers. 20gallons is bare minimum and im not sure there would be enough floor space in a 20 tallreally and pygmy corys are realisticly your only option.

It's sand

I have 5 neon tetras and 3 hasborus Cory's. They are a very small cory and soooo entertaining. If you see these guys don't pass them up!!
