Why did my guppy die?

[Abercrombie6202]

I bought this besutiful guppy with metallic blue fins
2 days ago!!

Yesterday: Half of his tail turned black

Today:theblakc part turned clear

2 hours later: He died!!

Can anyone help me figure out his cause of death?

sounds stress related...did you check the disease database?

Either rapid onset neon tetra disease, rapid onset fin rot, or really crappy tank chemistry. Transport stress probably made the fish susceptible, and tank conditions did the rest.

same thing happen to mine.... i have even worse case... i bought 3 round of 5 pairs.... all die the same way....sad...
i have other tetra & cory in the same tank they're all fine till today.

I noticed that when i bought it that it's tail was kinf of black so i'm guessing it's because of the tan it came from!!

but for mine, they all looks fine. healthy and active, nothng wrong untill the 3rd and 4th day then the the tail start to turn black and the fish become weak and stop eating. The next day the tail turn clear and some already gone. I've chext thru the disease database but found nothing.... im still wondering what happened...

What are your ammonia and nitrite levels?

0 and 0

How did you acclimate the fish to your tank? How long did that take. 2 hours is very short, so I have to say transport stress + the shock of going into your water chemistry. For wei, osmotic stress can take a few days to kill them
