This has been a terrible week!! I woke up a couple of days ago to find my 22" silver aro dead and now today. As you can tell from my list of tanks i have a 396 Gallon tank with 4 motoro Rays and now only 1 Silver Aro. I came home today to a tank with my 8" male motoro that has a spine that it looks like it went through his mouth and is sticking out his body, i think just missing his lung. Will he survive this? and should i add salt to fight off any infection? I will post pics as soon as i can downloud them.
