Hey guys, so I rescued a cute little oranda from a tank at petco where every other fish got sick and died. Now, he has been perfectly healthy and nothing has shown up. From what I could tell, one fish was sick (his eye was sunken in and he was half eaten to death until something killed everyone else) it looked like it could have been ich. Now, he does NOT show any symptoms at all, and I couldn't quarantine him and he kept escaping through the divider in my tank. My question is, if something were to show up, when would it? Nothing looks wrong with him. He swims around, eats, and looks healthy, other than a couple of missing scales. I have had a close eye on him to make sure I can take him out if something comes up.
