Instead of doing a salt dip I decided to do partly what John Sr (snookn21) suggested. He suggested dosing (normal not epsom) salt at 1 cup per 15 gallons or about a tablespoon per gallon. Last night I dosed half of that ( 2 cups (16 tablespoon per cup) in a 75 (~half tablespoon per gallon) ) and I monitored the tank for a couple hours.
This morning I did not observe a mad dash of the Alenquer and after talking with John just now I will do a full dose for three days starting tonight. Basically treating for externals. I'm hoping for improvement so crossing all body parts. Note that this is being used on wilds.
Also while talking with John he mentioned that he has had discus do exactly what is happening with my fish. A mad dash and dead a few hours later.
He has no clue to the cause of this.
