Doesn't it feel like the marketing for PRL was widely successful? Look at how just the mere mention of PRL in the title can often sway people's opinions. Alot of folks have their own opinions on what qualifies a PRL/JRB/CRS, and that is a great thing. I've seen so many people label their shrimps as a PRL to make a sales, and guess what? IT WORKS! Because it works, it will continue to happen until we get a bit wiser. I think this is the root of many problems.
Calling shrimps PRL is so easy now that EVERYONE has PRL. I think it's harder for find regular CRS now then it is to find PRL. The problem is rooted in those few up the chain who first did this trickery. Those that buy their shrimps from such folks will continue to call their shrimps PRL (because they bought it as PRL) and so the chain continues. Then there's names and brands that often gets associated with PRL... Benibachi, Crimson, Ebi-Ten, Ellen Wang, MK, etc... Often folks don't even know the true lineage of their bloodline, yet they continue to call them such bloodline.
Hell, I was in HK a year ago and I asked for Nishiki PRL and the store owner pointed to a tank which were clearly NOT Nishiki. I even asked for a certificate and he said he could just PRINT one out for me! Bahah!
This is why I have to agree with ShrimpyDaddy and say that... instead of buying shrimps based on the brand or bloodline someone says, instead buy a shrimp based on the way it looks. Bloodline and lineages means nothing. There's really no way to trace such things and majority of the time those selling you a name brand shrimp are lying to you for a quick buck.
If you have the opportunity to visit the breeder and/or know the source your shrimp is coming from is reputable, then buy it. Never take anything at face value because that's how you'll always pay more and get less.
