I do like snails and I think they are tasty. :) I'm a big fan of nudibranchs because they are pretty, but sadly I don´t think there are any freshwater species. The freshwater shrimp site was pretty cool and I found a lot of freshwater shrimp being sold in Petco but I haven't been able to find edible freshwater shrimp that can grow in a 10 gallon tank or requires brackish water for development. Those Black King Kong Shrimp are cute, but I definitely wouldn't pay that much for them! :)
I would really like to get some crayfish because they remind me of lobsters and I'm doing my thesis on sustainable lobster fishing. I looked into the red claws you purchased and it costs $75 just for the box, which is out of my price range for a school project. I'm going to the New Fulton fish market tomorrow morning because I saw that they sell live crawfish and snails. Do you know any other species of crayfish that would be suitable for growing in a small aquarium tank besides the red claw?
