Todd, if the polyps are indeed Hydra, so far as I know, they don't have
the medusa stage. The "bladder" may be the gonad. The only truly
freshwater medusa I know is Crespadacusta sowerbyi, which has a polyp
stage, but though the medusae are common (but sporadic), the polyps are
seldom seen, being minute. The medusae are about the size of a nickel
up to a quarter, and are usually found in pelagic areas of large lakes
and reservoirs.
