Had 15 goldfish for a few months, then about a week ago they started hanging out on the bottom of the 20 gallon tank and only have a few left.
I changed about 50% of the water twice, had the water tested the other day and it is fine the temp in the tank is around 68-70.
No idea why our goldfish suddenly stopped swimming around and started hanging out on the bottom of the tank not moving. They have been dying 1-2 a day and we have tried several things to try to get them to respond!
