Yea those are Thai micros. They were what I was originally going to get for the tank until someone else started the thread about the mud crabs. According to some of the articles, on mud crabs, they can and do have a full life cycle in fw bodies of water. Hopefully it can be repeated in the aquarium setting. If i remember correctly Thais also can do a full life cycle in fw but no one has been able to repeat the process in the aquarium.
ROLL TIDE ROLL!!!
