Hi guys..im new here. Ive had 2 bettas…in 2 seperate tanks for about a year now. They were given to my kids as a xmas gift last year. I keep them each in a almost 1 gallon tank. But would like to upgrade their home. Can i keep them both in 1 tank w/ a divider? Or are 2 seperate tanks better? I cant spend tons of $$, dont have alot of space for their bigger tanks and dont want to get more fish …so i dont want to get like a huge tank. Also…will want a heater and filter….Can you recommend what kind of tank i can get for them please? Pics and where to get it would really help too. Fyi..im in chicago suburbs.
