I'm all set up and "think" I've begun my cycling process. Now I'm starting to wonder if I bought the right right of shrimp... It's the kind in the circular container with the dip in the middle (making me hungry just thinking about it) I noticed last night, AFTER I put two of the small shrimps in the tank that the container said cooked... Are these okay to use or do I need to hit up the seafood counter for a couple of fresh dead shrimp?
