Hello, I'm going to make an endler tetra patio bowl with 20 gallons planted. I was wondering how many endlers I could put in there (male and female mix). The water temp is going to be around 65-75 during the whole year. And with those would you recommend any tank mates? Or none at all? THANK YOU IN ADVANCE 
Also would it be better to do a mix of genders or all males or females? tyHello, I'm going to make an endler tetra patio bowl with 20 gallons planted.
