I was looking in my tank today and noticed an invasion of baby MTS. all of them 1/8" or smaller. The only thing that has been added to the tank in the last 6 months is 3 large (32-36") pieces of bone dry Manzanita driftwood on Friday. Is it possible for eggs to have stayed on the driftwood and then hatched when introduced to water? I dont recall seeing any at all early last week. I dont have any plants in the tank as of now, I am about to do a major tear down and reset of the tank and go planted here in the next month or two. As of now its just a large "stump" of driftwood, the 3 large Manzanita pieces, and river rock substrate. I dont mind the snails at all and welcome the new life to the tank, im simply curious. Thanks all.
