What’s up with my killifish?

Ammonia and nitrites 0ppm

My gardener killifish have white patches on them, maybe it’s missing scales, I’m not sure from what. Getting nipped maybe? I have a couple chiclids that can sometimes be meanies.

Unfortunately, the spots are showing up blue in your pics which makes it hard to really diagnose the issue. See if you can get a close up pic of the area under white light.
What kind(s) of cichlids and other fish do you have in with him/her? I see a Neon Tetra and an Empire gudgeon. What else is in there? Also, is this a wild caught or domestic raised color form?

She is one of two domestic Gardner killifish. The other one is a male who has a small white patch but wouldn’t show up on a photo. I have a dojo loach, 2 cardinal tetras (I had 6 but the rest were eaten by the acaras), used two have 2 male guppies who were torn to shreds and eaten by the acaras, I have one empire gudgeon, 2 very peaceful angelfish, a bristlenose pleco, 2 male and 2 female threadfin rainbows, an electric blue acara, and an albino threadfin acara. The acaras are by far the most aggressive although that’s mostly during feeding time and they don’t go after the other fish 24/7. Once i get home at the end of the day I’ll try to snap a better picture of the killi.
