    randomly notices while feeding my corydora is literally missing his face (picture attached)
    I’ve read up on hole in the head disease but have no idea how he would get the parasite. I’ve checked ammonia nitrate levels and they are at a .15 the other fish in the tank show no signs of other disease.

    Anyone got any leads or suggestions?

    Currently treating the tank with rapid cure Incase parasite.

    Definitely not HITH.
    I suspect the substrate / gravel is culprit.
    The grains / pebbles are so big that food will get out of reach pretty easy / fast.
    Corys trying to reach it will easily damage themselve.

    Having too large of gravel, which results in food being trapped, can also cause an ammonia or nitrite spike, which cories are going to be closest to.
