My PK shrimp came in today I purchased off eBay. Excellent packaging, no deaths, and a very nice assortment of large to small sizes. I also believe I ordered 10 and I got more like 15. Currently tank raising them in my garage over winter. I realize ultimately I’m gonna need thousands. Guess we will see how well they tank breed. Water is currently set at 75 degrees as I read this was optimum breeding temp. I have filamentous algae and coon tail in there. They really seem to like picking through filamentous algae the most. I’ve also noticed they like to search for food in groups. Will be fun to watch them grow.
