Aggressive?

Is there a way to tell if a betta will be friendly with your other fishes prior to buying them, or is it more of a chance buy? Curious because my betta fish recently passed away in my 10 gallon tank and I'd love to replace him, but I don't want the replacement fish to terrorize my current stock (my betta before he died was totally chill with the other fish).

Unfortunately there is no real way to tell, even the most seemingly passive betta could turn and attack tankmates. But it's best to introduce him last to the tank like you would have to do so that he has no territory to defend so he's more likely to accept tank mates rather than if you had him in first and then added tank mates after.
