6 months ago I bought 5 harlequin rasboras. I've had a hard time adding more because the ones in the fish stores look significantly different.
Mine are a golden orange. The ones in the stores have much more violet in their color. They also have a very solid triangle, mine have a triangle that is compressed to a line towards the end of the tail.
I think I got a batch of some subspecies that is colored slightly different than most harlequins. Mine actually look better, to me. I'm I right?
