    Hi everyone! I’m new to the forum but I wanted to seek some help with a situation I’ve been having with one of my platies.

    One of my platys has had a few growths on her head / gills that have been developing and growing for a few weeks now and I’m not sure what it is. She’s been acting fine, and eating normally. My other fish don’t have this problem. Anyone know what these are? I have attached pictures of her growths.

    Water parameters:
    5 gallons
    Ammonia: 0 ppm
    pH: 7.6
    Nitrite: 0 ppm
    Nitrate: 20 ppm

    There’s four fish in total in the tank currently. Two guppies, and two platies. I’m following the 1 fish per gallon rule, (for guppies/platies only) but I know that a 5 gallon tank is very small in general. Is the tank possibly overstocked and may have caused this problem on my poor bumble bee platy?

    Looks like melanoma to me .
    Common issue in black swordtails and platy unfortunately.
    I would euthanize the fish or watch over closely so it does not die unnoted in tank .
