Well I heard a rumor on the forums that guppies could be acclimated to saltwater, and so I thought I would give it a try because I have a lot of guppies and more every day. So I placed 7 guppies in a tank with their normal freshwater, and slowly drip some of the saltwater into the tank. I let them live in the "brackish" water for about a week. After they seemed healthy and normal I started to drip acclimate them into full saltwater and placed them into my saltwater aquarium. I am very happy to say that they are alive and doing very well in the saltwater aquarium they have now be in there for 9 days.
