fatman.....Only some pods are bad. They can be parasites. (think wood tick or deer ticks) I had to pull about 20 off of a batch of seahorses we got in at the LFS once. FW dips and praziPro didn't get them off. It was NASTY!! Not to mention scarry for fear of causing secondary infections on the seahorses from the open wounds. Their mouths are like fish hooks, goes in easy, comming out is not easy at all.
