Help! Sick African Cichlid


I just discovered this pimple looking thing in one of my African cichlids. What is this and how can it be treated? Thank you for your help.

I've never seen anything like this. The following questions will provide helpful information:
  1. Is this possibly a wound from a fight?
  2. Do you have a water test kit?
    1. If yes, what are your water parameters?
  3. What temperature is your water?
  4. How big is the tank, and list numbers and types of fish?
  5. How often do you change the water?
    1. When was the last time you changed/cleaned your filter/media
  6. When did it appear, and has it changed?
  7. How old is this fish (or when did you buy it, if unknown?)
  8. Have you treated the water with any medicines?
    1. Which medicines?
    2. Did you remove the activated carbon/charcoal from your filter?




This looks like a start of hole in the head disease (HITH).

The white pimple stuff is basically a cyst pushing out of the skin, which starts they HITH. Also another symptom of HITH is the line that you see that travels from the top of the gill and straight back towards the tale. Your picture shows this. Basically it’s the nerves pulling apart.

To treat this you will want to QT the fish and use a drug like API General Cure (APIGC). You will need to treat him with APIGC at least 2-3 times.

The way HITH starts is due to poor water quality and/or poor diet, like bad food.

Hope this helps.
