Bought 4 orino's (2") from shark aquarium. came in Friday. I left them alone in the dark until Sat AM. 2 started feeding ok, 2 did not. I noticed red lesions on both. Added salt and Melafix hoping it was just from shipping. Both are dead this morning. What should I do with the other 2? Don't want to lose them. Should I treat the tank? Here are pics. They are the only inhabitants in a 45 gal growout tank that I just moved 4 healthy monos from into a 240.Thank You.
