I do not believe death is being wished on your poor flounder. The reality is that your tank is not cycled, you have fish that are not compatible, and fish that require expert care. Those things combined will lead to the untimely demise of your tank. Your tank may go on for a little while, but soon enough the fish will be on a downward spiral. I would continue to urge you to research all your purchases and do not make impulse buys and focus on building your live rock and properly cycling the tank. (hey, return the liverock, damsel, shark egg start over keep posting about having a flounder and shark egg and in a year show pics of a flourishing tank with suitable inhabitants, tons of coralline, and perhaps coral if you want to go that route). This is my last bit of advice for you!
