Thanks Beth & Terry,
I feed the fish flake and brine, which I've been soaking in Zoecon for the past week and a half. The fish "acts" normal, eats & swims like the first day I bought him 3 wees ago. The tank has been set up since Jan. 1st, 2003. I do 5% water changes weekly, with the last three being with ro/di water. The parameters of my tank are: nitrates=5, nitrite=0, salinity=1.023 (+/- .001), pH=8.2, ammonia=0, calcium=375. I double check my readings with a reputable lfs every other week. Their readings agree with mine. The color seems to have faded over time, not all of a sudden. A friend stopped by and thought my angel looked a lttle thin (compaired to theirs). I had cut back feedings to every other day to try and cut back on an algae problem. I clean the tank (glass) on Sunday and by Wednesday, the algae had started growing back. I have started feeding the fish on a daily basis again.
I noticed now there seems to be a grow (possibly a parasite) on the side of his mouth, that extends outward. I will try and get a picture and post it. I'm also going to be setting up a QT tank this weekend. Should I place him in there after the tank has cycled. I plan on using the the water I take out from my water change of my main tank with additional ro/di water to start cycling the QT tank.
