seems like my turbo snails are producing baby's!! have 6 mexican turbo snails in a 90 gallon and now there are many many little snails all over the place. Question is how long does it take for the baby's to get a size where fish wont eat them, like maybe the size of a marble, currently they are about the size of crushed coral pebbles. wondering also if they will keep breading and if this might become a problem because the 6 adults do a really good job of keeping the tank clean as is with out thousands of baby's helping out.
