gold mystery snails! i have about 10 gold mystery located in tooele. raised in utah water! they are about the size of a quarter right now but growing very fast. mystery snails are not hermaphrodites meaning they do not asexually produce like many other snails species and need a male and female to produce. they get pretty large about the size of a golf ball! they are amazing at eating left over fish food and keeping your algae down. message me for more info
