Re: 2 Fancy Goldfish Acting Strange

Thank you for your response!
They are the only two fish I have. The tank is 200 litres, 100x40x50, with a sand substrate that's probably 3cm at the deepest mound and 0.5cm at the shallowest.
I try to aggravate the sand whenever I change the water. There are a few smatterings of gravel too. I kept it in a small pot in the tank when I switched from gravel to sand to help bacteria levels and the fish kept playing with it so I left a few areas in there.
I do a 25% water change weekly and use Interpet Bioactive tapsafe plus. I also add Love Fish Filter Boost. I do regular spot cleans with a large pipette.
I have been using Ciano water test strips. The readings are:
NO3: 25
NO2: 0
GH: 14-21
Cl2: 0
pH: 7.6
KH: 10
For ammonia, I have been using API test strips which give a reading of zero.
I was previously feeding them Aquarian Coldwater flake food and floating pond sticks but I switched to Tetra Goldfish Gold Japan because I thought maybe the floating sticks and dried flakes were causing these problems. I fasted them for 3 days last week and saw some improvements in the black moor but that's when the fantail seemed to get worse. I went back to regular feedings but when the black moor got worse and the fantail showed no improvement, I decided to fast them again because I'm seriously lost. I've already tried interpet anti internal bacteria and I didn't want to overmedicate.
I rescued these fish from my last boss who was going to flush them because he didn't want them in the office anymore. I'm a complete fish novice and I don't want to have saved them from a terrible fate just to subject them to some other horror.
