What can you do to calm your angry parents?

My gold fish's fins are darkening up and dying. What can I do to stop this?
If your fish does that. You should check for any electronics in the water. Especially the heater. That might sent out electricity instead of heat slowly burning the fishes and killing them. They would heal by themselves.
What would you do with an old game or devices?
My advice is to give it to a friend, sibling, or cousins. Recycling it to stores are useless because the money you get is far lower than the price you paid. Giving it to a someone else is better. They don't have to buy a costly one.
