I'm putting together a heavily planted 110gal.
I want to try and keep two male Bettas. I've talked to two "experts" at local pet shops, and they both agree that in a tank that large, so long as it's heavily planted and has plenty of shelter, I can keep two Bettas in one tank.
What do you guys think?
I've been successful in getting my one Betta now to get along with fan tailed guppies. He flared and attacked them at first, but I put him in a solitary container and flooded the tank with fancy guppies for a couple of weeks. He was mad at first, but then he got used to them. I fished most of them out later, and then let him loose in the tank, and he's not attacked anyone. It's been weeks, and he's getting along great.
