What happen to my guppy?

[Cmlee]

hard to say...
I have my own breed of guppy and suddenly all clamp fins and one by one die...
I also have my own breed of guppies suddenly have dropsy out of nowhere... and then die..

So guppy sellers can survive

Yup, if the substrate is already harbouring the pathogens/fungus, no amount of water change would help. Start all over again with clean filter media, substrate....etc is the only way.

How did such disease come about? My fish gotten this too and whole tank of fish died. I do water change 2 times a week, don't know why such disease still happen. Anyone knows?

you can try change 50% water everyday and see for yourself.
hope you dose anti-chlorine when do water change.

A healthy fish will have a layer of body slime/mucus to protect them from parasites and fungus. If your water parameter is in good condition, I think probably your fish was injured or maybe stressed. Fungus usually go for rotting stuff instead of healthy fish.

Agree with bro Bern.

Also, even if facing minor attacks eg infection, healthy fish will be able to recover better with treatment than those in weak health. That is why it is so important to ensure that one's fish is kept in tip-top condition by good practices.
