Ely's (hit or miss depending if he has them in stock)
After all those are done (if you live in North NJ)
I would hit up Aquabid or buy them online. I bought 35 Amano's for 25 $ + shipping. roughly cost me about $1.25 per shrimp.
There is one guy on the forums that sells Yellow Shrimp. good quality, but my rams/bumble bee gobys/loaches devoured them like a pack of wolves. they were small fry. I am going to start up a shrimp tank, I think.
