Wart like bumps appeared on this fish 5 days ago. I raised temp to (84*) and added aquarium salt. Last night the TSN was swimming a little crazy like it was trying to scratch itself on the rocks. Today (see photos) I see that is exactly what it done. scratched the bumps off partially. This fish is a little over a year old. This tank has been its home the whole time. I do 50% water changes every sunday and clean the mech filter sponge. The temp is usually 80* the Nitrates rarely go above 20ppm. I have well water that is 7.6 ph and zero nitrates. Can someone identify whats going on here please. I have searched for a match to these bumps for 2 days and If this needs urgent action of some sort, I dont want to put it off any longer. The bumps are in 2 spots. just behind the mouth and in front of top fin. Thanks in advance for your help.
