I have six fancy goldfish (3 inches each) in a 75 gal planted tank. Last summer I had an anchor worm infection and had to try 2 different commercial products to finally beat them over several weeks. The last product required I remove all the plants and change the water daily for several days. I also took out the carbon filter pad during this process and replaced it with a new one when done.
My poor fish developed a dark skum which finally wore off. Since then all the goldfish in the tank changed color: Black Moor (turned bronze) all the others lost all black pigment and a white ranchu lost it's red highlights.
New fish I have added to the tank months later also lose their color after a few weeks.
About a month ago I replaced the light but have not seen any change.
I feed a pellet food and suppliment occassionally with frozen brine shrimp (green algea enhanced). I also keep replacing certain plants they like to snack on. I keep the plant temp around 80, for the Otos which I also keep for algea control. I test water conditions with each weekly 20%-25% water changes.
Does anyone have any suggestions or can you point me to where this may have already been discussed?
