Two gold white minnows died

[Cermet]

No fish can survive in a small tank in most houses without proper temperature control - temperatures change too much. In the wild, temperatures for most tropical fish change very little and this takes months. If a fish need cool water you need both a heater and cooling unit or a very large tank that holds temp (ponds are good for goldfish.) Letting cool water fish get hit by daily swings of even two degree's is bad and will harm them in the long run.

And yes it is always good to research first, you have no disagreement from me there, and i did do research on minnows. They stated they could survive the temps of my tank. Obviously i didn't do through enough research.

When you research, it is important to look up many sources and read them all to find common ground. Information about specifics is often different from one source to another. Find credible sources and research thoroughly, don't just read until you find what you want to hear, but find good solid information about the fish you are interested in buying. Use your brain and think, does it make sense that a cold water species would be comfortable long term in tropical temps? How credible could the sources that say this be? After you have gathered all the basic information, read it, and understand it, then ask questions of those who have experience. Several people on this forum are credible sources and there is no reason you can't or shouldn't start, include, or end your research here, but don't forget to do your own research as well.

One more thing, bodies of water in nature can and do change temperatures very quickly, often several degrees from night to day and back again, but in nature the fish can go deeper to stay in cooler water or come nearer the surface to stay in warmer water. This is why it's important to have a steady temperature in your tank, the fish can't go deeper or surface when needed.

I will cut back on the feedings...

When? You have been told this repeatedly and you have replied with this repeatedly.

When will it happen?

+1 - And excellent point about 'weak stock', It's about as common as Neon Tetra disease IME, Which is to say that it isn't.

Ever notice that you only very rarely see it happening to more experienced keepers but it apparently happens to newbs on a semi-regular basis?..
