[Dash]

I have to admit this was one addition I didn't inspect as carefully as I usually do. I was so worried about getting it into the tank without exposing it to air. It sure goes to prove how easy it is to bring a pest into the tank. On the other hand, my examination of it in the clear container also showed a low-growing cool sponge on the rock. So there's good with the bad.
