How many tetras can I fit in my 20 g high

[Perbud]

Dear all:
I have 7 glofish, and 6 albino cities in my 20 gallon high. Do you think it is ok to add 6 more small tetras?
Thank you

What are albino cities? Sorry, I've never heard of them
What tetras are you thinking of? I would just add to your existing groups or leave it that way, especially since its a 20 high.

You could add another school of small tetras, but I would not. Personally I would leave it be. IMO, In a 20 tall tank a group of tetras and a group of corydoras is more suited than 3 groups.

Most tetras even small ones need room to swim and shoal. If you had a 20 long I would say add few more but a 20 tall does not have the swimming room (length)
