Question

Answer 1

I think your last comment tells a lot. You just got your fish, so they're not only young, they're stressed from being moved. Stressed fish also don't show the best coloration.

To help yours color up, give them good quality foods, good water quality, and plenty of hiding places (plants are good for making them feel that there are places they can dart into to hide). The rest will come in time.

Also, make sure the photos you're looking at and the type you have are the same species and in the same conditions. A blue-finned tetra can be a white skirt tetra that's been dyed (also called blueberry or berry mix tetras), and as with any dyed fish, the color fades over time. The name "blue tetra" can also be applied to Columbian tetras.

Answer 2

Are they young? Sometimes younger fish aren't as colorful but they get their color as they age. You can buy special food that supposidly enhances the color in fish but it's probably better to just wait it out.
