Hi, this behavior started this week , the big one is chasing the little one. they live together for almost a year and thats the first time thats happened. its happening a few times a day. Do you know what is this? Is it a game? attack? Mating behavior? thank you

My guess would be stress from living in such a small tank

See "In The Aquarium" in the link below

It's telling the small fish to get out of its territory. With growth comes smaller territory.

Yes they can thrash each other real well,
