I am going to get about 7 female bettas from Styx for my long 20g but wanted to know how I would go about opening the box, like would I just open it in normal lighting or dim lighting. Also how long should I get them used to my tank, could I just do what I do with other new fish which is to float bag for 20 min and put some tank water in bag, wait 5 min then net the fish out of bag and place them in tank?
