hi all im new to the having betta fish. Any type of fish actually, and wanted to show some pics of him.He's a crowntail betta that is light blue but goes purple in the fins.I've been reading up on bettas have him in a 1.77 gallon tank with a couple of plants and barrels to hid under.I'm planning on upgrading to a 5 gallon tank soon.The only thing that concerns me is white stripe on his head to his top fin.Is that a stress stripe from living in a cup?
