What size tank, what filtration, how many waterchanges per week, how large are they, what are the tank perms (ammonia, nitrate, nitrite, ph)? If a fish has died then there is a problem with your tank.
Because bedside manner is for wussies!
But sorry about your loss. The setup is fine. (It's normally safe to assume goldfish tanks are poorly set up and maintained) what symptoms was flounder showing and when did they start?

25-50% they are not that big. Sally under 1 inch, Sadie 1 1/2 inch, Waffes 4inch Dory 4 1/2
72 gallon, ammonia none,nitrate 0, nitrite 20, and ph 6.5
Flounder was very sick,after he died I check the tank and its fine.
