Most likely scenario is one or a combination of the following:

- Too many fish added at once = ammonia spike = disease/death

- Tank too small (goldfish need more space than other fish) = biological filter crash (beneficial bacteria couldn't work fast enough).

- Improper water change/ too much water removed or water not properly conditioned = shock from chemical changes or temperature changes lowered immunity

- Not changing water often enough (goldfish produce higher ammonia levels and need more changes and a more powerful filter) = fish overcome by ammonia and waste

- Introducing a sick fish into population (this would only overtake them all so quickly if something was already wrong in the tank.

Those would be my top choices to look at first. Probably a combination of several problems. The symptoms sound like a classic case of ammonia poisoning, combined with a possible ich infection. Take a cup of your tank water to a local aquatics pet shop and have it tested for ammonia and nitrites. Best to know your mistake before purchasing anymore fish and wasting your money!

Best of luck.

sounds like a bad case of ick it can kill the fish if not treated you need to clean out your tank if u dont have any more fish but if you do still have fish you need to treat them for ick
