Thanks and yea I guess I didn't give him a chance. Pardon my inexperience this is my first attempt at an aquarium. I have always wanted one and when I recieved the betta bowl and Orestes as a gift I figured it was a good starting point.
As far as plants and decorations, I don't have live plants, I was hesitant cuz its my first time, but i do have 5 plants, 3 are off to one side and are relatively close because i figured the dense vegitation could serve as cover and the other two are spread out in the tank. I also have 2 cave-like decorations.
Thanks for the advice, it was only one nip and that was hours after his introduction. He was fine up until then although he would flare if they got close but he never acted on it. I think I got scared when I saw him nip so I overreacted. When I get home and can watch them closely, I'll put him back. Maybe I'll pick up more plants too.
