Good to see that the fish survived your vacation.
The last time that I had a pet sitter to feed my fish she was shoving food inside of the lamp, as she didn’t understand my fancy hood, and could not locate the feeding hole.
The fish in one tank didn’t get fed for four days but they were fine. They all got together and picked somebody to eat while I was gone.
Tut tut

Your poor fish sitter friends didn't stand a chance, they were defeated before you even went away, lol.
