I’ve had these two baby clowns and the jawfish for a week this past Tuesday. The clowns have been eating like hogs and swimming with no signs of stress, or any issues. The jawfish has been swimming and hiding out as they do, but he hasn’t ate, he’d was continuing to blow food back out of his mouth. I had a container of sand, and plenty of places that he hid in during quarantine. We were afraid he may starve so when I got home from work we were going to acclimate him to the other tank, but instead when I got home they were all dead. We can sort of see white areas on the clowns but not sure if this was the issue. The clowns came from Live Aquaria and the jawfish came from a LFS, which I should have known better to quarantine them together but we all live and learn. We think it was the jaw fish as he wasn’t eating and was scratching up against things, but I wanted to see if any more experienced reefers could help identify what may have happened. They were all completely fine at 9am, but at 4pm they weren’t. This is our first dead fish experience. I have to research on how to clean the tank properly too to prepare for new fish. What could kill them this fast?! Thanks in advanced for all the help.
