When I posted this I ment to say I water to put mollies in the tank after it cycled to make sure that all my parameters were good for fish. I was planning on getting a Mollie for a month than taking them out and putting them in my sisters tank. I figured that I would want to try to put a fish in there that is not too expensive first so I would not kill it.
You can't just throw a molly in a saltwater tank. It has to be acclimated to a higher salinity environment over the course of several weeks.
You're better off just getting what you want to begin with. A lot of times it's a pain to catch a fish once it's been introduced to your tank.
