Hi! Who is it, when I bought that said Rineloricaria castroi?
thanks.

Welcome! Can't help you much - I can't find the fish name you are citing... but will give you a bump. I guess you are from Russia. It'd be good to indicate that unless you prefer to remain incognito and keep people guessing what country is Voronezh

When it comes to identifying these fish, it's always good to first rule out . These are the most common species in the trade.

P.S. ignore the vs. confusion. There's a small taxonomic issue going on there (see here).
