3 days is nothing. I wouldn't have bothered having anyone mess around with my tanks for that little time.I had someone over for the first of the three days that fed them frozen shrimp and that was it
That looks like damage like from fighting or running into something. Hith doesn't happen overnight, it's a process of improper care over a longer time period.
3 days 2 dead fish 1 damaged fish doesn't add up with pristine water parameters. Was there damage to the dead fish bodies?
