20 gallon long set up

[Terry]

Hello everyone, I would like advice from you since you have more experience in fish keeping.

I have a 20 gallon long, and want 5 or so diamond tetras, and 1 apisto. My filter will,be a sponge filter. 
 

is this too many fish for a 20 gallon long ?

 

thank you

No, I don't believe that is too many fish.  In fact you could probably add a few more of the diamond tetras.  I wouldn't add them all at once, of course.

+1 to what @JettsPapa said

 

In addition, the needs of apistogrammas may vary from one to another. So I would advice try to get as much info as possible regarding under what conditions they have been being kept before you get them. Usually staying in their desired changes would be a better choice. I normally keep any fish in my 8.0ph but I setup an RO tank for apistos. Some may be more okay with wider ranges.

What are your parameters like? 

Here you can find great info about apistos:
