2 new Orange split-tail like Fish (Could they be Copper Harlequin?)

Bought two new freshwater fish today after an aquarium shop walk. I forgot to take notice of their fish name so I can't be so sure what they are called. If anyone can help me to identfy them it will be appreciated. I think the way they have their tails look like split-tails are pretty interesting. They are quite small and I have no idea how big they will grow or last.

Hope they'll enjoy their new home.
