Hi! i am new here and would like to introduce myself. I have a 10 gallon tank and 2 1 gallon tanks. In my 10 gallon tank (freshwater), I have a cory catfish, a dwarf gourami, and two small male guppies. They get along well. In my 1 gallon tanks (freshwater), I have a betta in each. One is the normal long fin betta and one is a crowntail. They are very healthy and active.
I live in a moderate climate, so I had to get a heater for my 10 gallon in the winter. It works well. 
Thanks for reading! -maxwellag
