Hello all, i am currently wintering 4 goldfish from my pond in a 100 litre tub in my garage with a heater set to 19c. They have been fine and happy swimming around until I did a 90% water change. Now they are darting around the tub and sitting at the bottom when i got close. I sat still next to the tank for 20 minutes and they are still doing the same. I do these water changes every few days and they have been fine. What's wrong with them?? Please help
