Injury or something else🧐

[Iris]

This is my 1 year old EB Accra. In a 55 gal with 1 other EBA and smaller tetra and one Angel. These Accra are same gender and I’ve never seen any aggression between them. When I walk up to or pass the tank one of these two take off and does collide with things in the tank including sponge filter,airstone, driftwood, seriyu stone.so plenty of things that could produce a scrape.  Doesn’t appear to be raised. Could this simply be an injury. I haven’t added any fish in 4 or 5 months and those two were flying fox & had been qaurentined prior, no longer in this tank.( needed them in another tank for bba removal) Parameters ph 6.6 ammonia 0 nitrate 0 nitrites 0         temp 78. Water changes every 2weeks. Light Gravel vac once a month

It’s hard to tell but it looks like an upraised scale. I wouldn’t say anything to worry about. When I had my electric blue Acara’s every now and than one would get something like that on their face. Just happens sometimes. If it’s fuzzy looking or like a bump than that’s a different story. Does it look like a scale? Is it rounded and somewhat translucent?

Definitely not raised and grayish not fuzzy at all the shape hasn’t changed in four days  it could be a scale

Injury, rather than an upraised scale it is a missing scale, possibly because it bumped into something. I should heal up which may take a little time. I recommend some API melafix or Kordon fish protector, to reduce the possibility of infection, a stronger dose of stress relief can also create a stronger synthetic slime coat which can reduce infection.

I don't know enough about this fish are they territorial fish? It is still possible that they will stress each other out even if they don't possess a real ability to hurt each other.
