Mysterious guppy death

[OrkyBetta]

Well, after a week of quarantine, everything was going great. Both boys were healthy, happy, and eating normal. Water params normal, up to date on water changes. Yesterday morning I found my orange male dead. The yellow male is fine, and the water was fine. No changes in anything, all I saw was my orange guy laying stiff at the bottom. Any idea what went wrong?

If there was no sign of desease/illness, water quality stats were and are perfect, its probably genetic; flame tail guppys are quite inbred and this can lead to a whole range of genetic problems including sudden death syndrome. If it was genetic, theres nothing you can do about it.
