With mollies, it can and has been done.
Mollies originate from brackish environments and can be acclimated to full saltwater conditions using the drip method or slowly increasing the salinity of the water.
This requires time and an understanding of how to perform the acclimation procedure (don't just dump them in a saltwater tank). Mollies can actually thrive in a salt water tank provided they've been adequately acclimated. Some hobbyists use mollies to consume nuisance algae and cyanobacteria from their marine tanks.
Cardinal tetras, on the other hand, are strictly freshwater fish and cannot tolerate full marine conditions...it would kill them.

im not sure about the tetras but they can get aggressive with other fish. Mollies can handle some salt but no a full saltwater tank.

If you get mollys that were raised in full saltwater, yes.
Cardinals are fresh water fish, so they cannot live in salt water.

A molly can tolerate some salt in their aquarium but not the same salt that's in a saltwater aquarium!

it must be okay to operate it even as there are fish in there. there ought to correctly be some die-off of the microorganisms that ought to regulate the steadiness of your tank slightly, yet this can sparkling up in a short era of time, assuming your tank is already cycled and this is only new rock you're including. To be secure, you should do a small water replace previously including the rock.
