Kate- Angels don't usually get fin infections unless the water is getting bad. Columnaris bacteria are about the worst and will eat up the fins leaving only the rays behind. Lateral line infections in angels is usually on or near the head, rarely any further down the body. True, sometimes there is hexamita (spironucleus) and sometimes not. You can kill the Hexamita and not cure the fish, and you can cure the fish without killing the Hexamita. But in angelfish you should probably treat for Hexamita anyway because they are so likely to have it and suffer from it. But is there something else going on? Is there an obvious infection all along the lateral line and on the sides? Maybe she introduced some new fish lately and brought in the "Angelfish Disease" aka Discus Plague. That would explain why there is a problem with the fins AND the body.
