Give them a bit and see if the color improves when they settle in. I like the male, he's not great, but he is nice and if his color improves that would be even better. The female, eh, but she might get better too with better care. My only concern and though for long term - you might find out in a month they hate eachother. After some good water and food, they'll perk up and feel better and start sparring.
