Question
HELLO,
my cat fish are turning white all over. I have checked the water and its okay.I need a solution please, i have spent a lot of money in bringing them up.

Answer
Hi Kenny:  I would try a water change to make certain that there is not something in the pond such as lawn fertilizer or even a pesticide that might be irritating their skins.  Pond water test kits only test for a few chemicals and out-door ponds are subject to all kinds of runoff and airborne irritants.  I would also check the quality of food you are feeding as diet can sometimes lead to color changes.... Hope this helps... dave
