My poor puffer fish just died which i had set up in a brackish environment.. does anyone know what i should do after a fish has died, i want to start a fresh water aquarium is there a special way of cleaning the fish tank?
If you are worreid about a disease, then you may have to clean it very well with bleech. If no disease then you can simply do water changes to get the salt content diluted if youwant to go non brachish. Also kepe putting a small amount of food in the tank to keep the bacteria alive and the tank should be ready for other fish as soon as you change 50% a couple times.
Youi might be able to treat the tank with coppersafe or some other remedy if you think it was a disease but make sure to keep feeding the tank so it stays cycled.
