Yea, it was your Zoo's. I was about to open the bag and put them in my tank and noticed all these red bugs. They were flatworms I am guessing. They look just like the picture Minh posted in the flatworm thread. The Zoo's are fine and open. There were also more than 7 Bristleworms in that little rock and 4 or more Microstars. Most everything survived except the flatworms.
