I have two male bettas [they have been in the same tank together for around 2 months and they don't fight!] and I also have three female bettas. I am planning on getting some new fish and I was wondering what you guys suggest what I should put with my bettas?
I would say, get a divider ASAP. Just because they are OK now, doesn't mean they will always be OK. One day you will probably come home to a dead fish.
What size tank is it, and what kind of filtration do you have?
I have a 20 gallon tank and a under gravel filter. Okay, I will go out and buy a seperater for my tank today. But, what kind of fish would be compatible with bettas?
