Longest Possible Safe FW Dip?

[daniella3d]

why FW dip? it's harsh on a fish. I would do a one hour dip with Paraguard and then yes quarantine the fish and if everything is fine after 4 weeks then in the display tank.

As for how long to FW dip, as long as the fish stand it, usually not very long, no more than 20 minutes or so. Paraguard is safer and the fish usually show no sign of stress. A 40 gallons aquarium is no bigger than any 40 gallons aquarium, it is still 40 gallons. A fish need its vital room to breath and have enough oxygen. If the aquarium is overcrawded and something goes on the edge than fish die from lack of oxygen. I see it so often. This is why I don't put any more fish in my 75 gallons although it looks empty of fish.
