My local zoo (ZooTampa in Tampa, Florida) recently had all their stingrays die at once. They're claiming it was due to gas bubble disease from a malfunctioning filter that supersaturated the oxygen in the water. It made me wonder if air stones can cause similar issues. I've read conflicting advice on this. I keep my quaratine tank heavily oxygenated since I know praziquantel can rapidly deplete oxygen and I just assumed it was a good husbandry practice for stressed/new fish. Any thoughts?
