I was hoping for larger shrimp
Written by Wendell Perkins on 17th Nov 2016

Quality is great. I got the package on time, they appeared healthy and there many more than I paid for. The description mentions the adult shrimp size, but you will be buying juveniles. All except one of them were the size of adult brine shrimp. My hunger striking seahorse did go after them, but could have eaten them all in one day. If you are looking for adult seahorse food, maybe choose another option. Response: All the cultures of Live Mysid Shrimp we ship are adult size as stated on the description page. You received Mysid shrimp adults full grown at 3/8" in length. Adult marine Mysid are full sized at 3/8" length. Live Mysid and Amphipods are the natural prey animal for seahorses in the wild. Mysid make the best seahorse food, seahorses eat constantly all day long, so they can deplete 100 Mysid in short order. Specially when the Mysid and adult seahorses are confined in a small glass box we call our aquariums. We always add quite a bit extra counts in our Mysid orders when we pack them.

Delivered the day Hurricane Mathew!

Not even a hurricane kept ANF from delivering mysids when I needed them ASAP for a baby cuttlefish! They arrived on the other side of the country in better condition than I would have guessed. I'm impressed. I have been wanting to try hatching baby cuttles from the egg and now that I know I have a reliable source for mysids, I am greatly encouraged.
