Bought this Fish at the pet shop today. Forgot it's name.
That pink fish

Your fish in question is a zebra danio GloFish; they're genetically engineered to have flourescent coloration. The giveaways for me were the shape of the body (minnow shaped, with zebrafish belonging to the minnow family), its size (small), and the striped pattern running along the body, parallel to the lateral line. Since the fish in your picture is in motion, it's a bit difficult to see, but it's definitely there (can be seen closer to the head).
And here's another image, where the coloration is closer to what you have. (IMO, the previous image has a strong contrast, especially with the black background)
This zebrafish is suffering from a bent spine, which accounts for the misshapen body. (source)
Also, it seems that the fish in the background is a black-skirt tetra.

1$\begingroup$ Seems like your identification is correct. I suggest you add an image from google here instead of telling to double check it. $\endgroup$ Jul 15, 2017 at 1:32

2$\begingroup$ Are you sure? The top fin seems much longer, the shape of the tail is very different, the color of the eye is different. I'm fish biologist, but I have doubts. $\endgroup$– RHAJul 15, 2017 at 20:20

1$\begingroup$ If I'm not mistaken, that's a saltwater fish. The tank in the picture, I'm 99.999% sure it's freshwater. Also, I agree with @RHA. $\endgroup$– user22020Aug 14, 2017 at 4:45
