holy cow cant believe you guys managed to dig this up. It has been a long journey since then, as you can see my tank was torn apart and completely redone.
Anyway to bring closure, i found the guppy buried beneath about 2 inch of gravel while taking everything out to redo my tank a couple weeks later. It hasnt completely rotted yet, so i could make out some color pattern and identify the poor thing. How it managed to get buried so deep after dieing is still a mystery.
Those guppies are just too fragile for my liking, nowdays i keep more "tough" fish like barbs and rasboras. Havent lost a single one yet :clap:
