[Neon Tetras in 10 Gallon Aquarium]

I am new here and just joined about an hour ago.  I hope to get good info on taking care of fish and fish tanks.

[Apistogrammas]

I have had a male and female apistogramma and they were a pretty hardy fish.  They like to have a cave to go to.  Mine laid eggs, and the fish carry the brood in their mouth.  They are a very nice fish to add to your tank.

[Neon Tetras in 10 Gallon Aquarium]

I was watching Cory on You Tube about making a simple aquarium with just Neon Tetras, but I can not remember how many Neons he said you could put in a 10 Gallon tank, with plants.  I was wondering if anyone could help me with this.
