Starting a 130l tank

[sparkee61]

Just put up "another" saltwater tank that is 130 gallons. How many snails, crabs and other cleanupers should I place in tank?

As a very, very general rule about one per gallon. But mix it up with different kinds of snails and crabs because they all do different jobs. They are some website's if you search that sell clean-up crews for different tank sizes. To my understanding they do not add really to your bio-load so IMO the more the better.
