I can use some guidance..........I woke up to find my talapia in only a few inches of water. Im not sure how long the fish have been without adequate water, maybe as long as eight hrs or more. When I found them they were still alive but struggling. So, I fill the tank with regular water from our hose, there was no time to gas off the water. Is there anything I can do to save them, they all look like there struggling pretty bad. Think the chlorine will kill tham and my plants?
