Fish Stock Question

[mark4785]

I was simply wondering how many black neon tetras would be too much in a heavily planted 120 litre aquarium (aquarium 1)?
I have stocked it with 10 alongside 4 Corydoras and they have been doing fine for the past year.
 
The problem is, I have a separate 120 litre aquarium (aquarium 2) with another 5 black neon tetras that I'd like to transfer to aquarium 1. Would this be a wise move or would aquarium 1 become over-stocked?

I would think you would be ok to put them into tank one.

Is your tank maintenance ie water changes regular? and of a good %

Ok great. Tank 1 gets a 50% water change weekly. 
 
It is stocked with hardy fish so the 50% water change doesn't bother them.
 
 
Thanks for your help.

I do big water changes too to no detrimental effect
