I became a foster mom to my son's goldfish when he could no longer keep them in his dorm. So my knowledge is minimal - I have an Oranda with a very cloudy eye. It's been that way for about a 10 days. He otherwise acts his usual "normal". The pet store said it was probably a fungus infection so I treated the aquarium with Fungus guard. - twice - following the directions on the bottle but I see no change in his eye. Does any one have any suggestions?
The tank is 30 gallons - I've had it for about 6 months - it's filter system is a Penguin 170 bio wheel and also a sponge covered tube type thing (sorry I don't know what it's called). There are 3 goldfish - a fantail, a "regular" goldfish and the oranda.
The test kit I used tested as follows
Ammonia 0ppm
Nitrite between 0 and .25ppm
the ph is 8.2 - and has been at that reading since November
Our tap water is well water with no cholorine ph 7.8
I clean the tank about 7-10 days - changing 5-7 gallons of water
I feed them Goldfish flakes - once a day and goldfish crumbles - once a day
Thank you.
