    Hi,

    One of my balloon mollies died tonight, it was healthy last night at feeding time, swimming about like normal & eating but tonight he was dead

    The strange thing is his gills were black, not red from blood but black, i have never seen this before

    Does anyone know what might have caused this, i have other balloon mollies they are healthy but i don't want to lose them to the same thing

    Thanks for any help.

    Sorry for your loss :(

    From looking at your profile, it looks like you might have some stocking issues. Which tank was this molly in, and what other fish are in the tank?

    Thanks

    I have just found another molly dead with the same black gills,
    These were in the 160 litre tank, i am a tad overstocked in this tank, i have 10 guppies, 5 bumblebee gobies, 2 bristlenoses, 10 cories 12 khuli loaches, and a couple of other fish

    I do 3 water changes of about 30% each week & i have had these mollies for about 6 months now, to lose 2 within an hour of each other its a bit worrying, the other fish all look fine

    Have you tested your water? Dark brown gills can be a sign of nitrite poisoning

    Edit: you posted as I was typing, your test results would rule out nitrite poisoning.
