Since your local, I can tell you for sure that our local shops in sacramento will give you cent to the dollar for freshwater dwarf shrimps. I've tried selling it to them before just to try and get the ball park price and it was not soo good. lol
Cherry Shrimps - Exotic Aquarium will take 20 at a time, they sell for $2.99 but they'll give you .50 cent per shrimp. Store Credit only. They don't take any other shrimps. No Amano, I tried.
Crystal Red Shrimps - JoJo's Aquarium will take 30 per month, I spoke with the owner personally over the phone. He doesn't want high grades above S. He's not able to even sell the few S and SS that he has at the moment which are $19.99 each. But I talked him into giving me a price for A B C grades Crystals and he will pay $1.50 each.
As far as Crystal Black Shrimps grades A B C and S, they don't want any due to the fact that it's not "popular".
Aquaworkz Aquarium will take Cherry and Crystal but it's priced at .50 cent for Cherry, $1.00 for Crystal Red Shrimps.
Capital Aquarium, Paradise Aquarium, will not take any shrimps.
I had a massive overstock tank, and needed a way to get rid of some Crystals and Cherry. Those were my past month conversations from the owners of those stores. You're better off just selling it here and shipping it out. Priority mail is pretty cheap these days.
I sell mines daily locally in Sacramento. I just sold 3 pairs this evening. What do you have? I might be interested depending on what you have. lol. Although my shrimp rack tanks are overloaded also -_-
Just post up a ad on craigslist and sell it there. I sold over a few thousands Cherry shrimps from people all over Vacaville, Dixon, Davis, Yuba City, Marysville, Rocklin, Roseville and had a few coming back for more. I also give extra, at least 5 extra when they buy 10. Buy 100 I'll give you 100 free. If you put in a fair handout, they'll surely come for it. And it was selling at $1 each. Try that! Cause I'm low at the moment lol so It might work!
