can't totally answer your question, but some ideas come to mind, as in how
long did you have it, versus how long it was supposed to live... it may have
been old age... or, it's even likely that it got an internal parasite if
there were any fish introduced in the last 2-3 months....

but I've seen it pretty regularly that after a fish dies, the owner will do
an autopsy to see if there were blockages in the intestine, digestive
system, and urinary tract, which are the three biggies....

Hi all,

It's always sad when there's a death in the tank. So the above died and
this morning when I fished him out, I noticed he had a very green belly.
It was not green like something growing on him, it was from the inside
out.

I'm curious if this is indecitive of some other problem or does this
happen to them when they die?
