Although A. agassizi is smaller than A. caca, did you ever see them locking jaws?? Look at the upper lip of caca! Is that a scrapes/wound??
How big is the tank??
White protrusions behnd the head and near caudal peducle, do they look like a mucle tissue protruding between scales??
If so, has it been exposed to low, low pH for long time or is this one pretty recent addition?
Google for images of Fish TB to compare. Keep in mind though that not all images provided are correct images thus dont jump to conclusions.
As far as wc, the idea is to keep water stablized provided it is w/in ideal condition to begin with. If you dont see a major/drastic problems with test results (pH/NH3/NO2), I would try to avoid any unnecessary wc. Constant changing of water chemistry brought upon by too many wc does impose more stress on the fish which may already be going thru complication.
Personally, never encountered self inflicted wounds unless provoked as Ive seen injuries/wounds caused by when fish are spooked/Tap on the glass, etc & from fighting...
If it does resemble certain characteristics of fish TB, early diagnose and treatment can do the trick.
Hope all goes well.
