Okay, so tonight I went to my local PetSmart (I know, I know...) to get a replacement bulb for one of my aquariums and in their tank of Rosy Red Minnows, I noticed something. It looked like a large shrimp or possibly a crawdad/crayfish?? I asked the guy working there what it was and he said that he had no clue because it had arrived as an accident in one of their recent shipments. Then I asked if it was for sale, and again, he didn't know, but didn't think so. He then told me to call the manager the next day and to ask about it and if it was for sale. He then looked at me and asked if I already had an aquarium and I told him I had a few, and to make a long story short, he gave me this cool creature for free!
...Although I am totally stoked about this new guy, I really don't know what he is. If any one recognizes this guy and knows what he is and how to care for him, that would be much appreciated.
Following are two pictures of him:
