I purchased a longnose butterfly fish last week and sadly, woke up to find it dead today. It was in a 75 gallon quarantine tank. I don't know why it died....water params were fine and it was eating mysis shrimp. I'm now trying to decide what to do with the QT tank. Should I tear down the entire tank and bleach everything etc, or can I run some carbon and use the tank again without emptying? Any thoughts are appreciated!
