What kind of Prochilodus is this

[G_sharky]

Hey guys....
I just bought these guys and the LFS sold them to me as flagtail prochilodus, but I've been looking pics of them and all the pics seem to have red or orange on the fins and tails....mine's are only about 1.5" has the stripe on the tail and spots on the body, but no color.......can anybody ID these guys....here are some pics:

Yours must be just too small to be colorfull yet.

I could never find pics of young flagtails on the net....so would they get that red or orange color on their fins as they grow bigger???/ cause I've read somewhere that there is a sprcies of prochilodus that stays silver with no colors and that only reaches 6 to 7 inches....

ive seen a silver proch at about 5 inches before. and ive had red and yellow tails as small as 2-3 inches or so. so im not sure they are the same fish. i know that the japanese classfiy them as different fish, a silver prochilodus and a color prochilodus. either way they are nice fish.

It takes them time to develop their colours, but mine are only 3" and are fully coloured.

the semaprochilodus taerinus is the colored-tail variety, and semaprochilodus insignus is the one that is noncolored... or was it the other way around..lol.

edit: meant to say colored 'dorsal fin' no colored 'tail'
