I took a Tupperware container and punched a lot of holes in the bottom (all around the bottom/side so it would drain uniformly/quickly). Prepared pH adjusted freshwater in another container. Caught the fish in the holey Tupperware container, pulled the Tupperware barely out of the water and let the water drain through the holes then put the fish in the freshwater. Watch the fish during the bath for erratic behavior, then pour the freshwater and fish into the holey Tupperware (I put another container underneath it to catch the water, let it drain. Hold the holey Tupperware barely over the tanks water line and kinda of nudge them out into the tank.
