I just transferred by Betta into an already existing 10 gallon tank with 2 cories, 3 tetras, and molly and a platy. I let him float in a bag for 15 minutes to see the other fish, then put him in. It's been about 30 minutes and they haven't attacked him at all, just checking him out. Thing is, he's just chilling in the corner and hasn't moved from there. Does this mean he hates it? Or do I give him time to adjust. He's a really friendly Betta who comes up to me almost lets me pet him.
