UPDATE: I received the WH and kept them in a bucket for a week or so to watch for duckweed hitchhikers and the like (none found). All 4 of the WH could have been stuffed into a regular sandwich bag upon receiving them. They have been in the PVC corral now for about three weeks and I don't think you could stuff them in a gallon zip-lock now. The water temps were in the low sixties when they were put in the pond and the temps are now pushing 80. I think their growth will accelerate as the pond continues to warm up.
