Alright I found some pictures. The first is a cremecicle molly. I have had these personally and my male was awesome! He hung out with our Red Blood Parrot fish.
Couldnt find a flame sailfin but here is a green one.. I am sure it looks the same just a different color.
The bleeding heart tetra... another cool one. I have a tank with nothing but tetras.
And the flameback tetra
i would stay away from the strawberry, blueberry and grape colored tetras. Those are dyed and are never healthy and is not natural. They take a white tetra and inject it with different dyes... not good. Dont recommend it...
