These are harlequins but a different species to the more comon ones. Have a look at below...it might help! Rasbora heteromorphe are the more common version correct but having researched a bit these are a bit different but still a version of the Rasbora heteromorpha.
"If anyone has ever kept the Harlequin Rasbora, they will know how beautiful this little fish really is, especially when kept as a good sized shoal in a well planted aquarium. It's red/purple/bue hues stand out very well under gro lux lighting, and photographs rarely if ever do the species any justice. There are at least two other species of Harlequin Rasboras - R. hengeli, and R. espei. These species are often over looked, as they do not seem to very photogenic, at least I have never seen a good photo of either fish. I currently own a group of R. hengeli, and I can say it is a spectacular fish, even when kept in hard alkaline water. Whereas the true Harlequin is mainly purple, R. hengeli is a brilliant red that defies description. It really has to be seen to be believed. I highly recommended R. hengeli to any Rasbora fanatics, or to anyone who wants something a little less "bread and butter" than the Harlequin. "

Thanks.
I was lucky with the pics, all the rest ARE very blured.
They are not the common type as Sarah rightly said, they are a little bit more expensive, but worth it.
Not harlequin Rasboras They have both species at my fish store, and I had a long discussion with the worked about them They are VERY closly related, and grow the same size. They are both the same price at my fish store, $2.50 per fish I believe.
There are 2-3 different species of fish that are sold under the name Harquelin Rasbora...I dont know what they are as I havent done too much research on them (never kept them).
You have espei rasboras (also known as false harlequins) I had a dozen until I had to give them away, great fish, tend to school up at feeding time and at night before the lights went out.
