My catfish has just died literally 20 minutes ago, and I removed it after 20 minutes. Should I clean the tank now immediately and do 100% water change?
It is a 5 gallon tank, fully cycled, has plants, aeration and amazing filtration system. I just don't want to do 100% water change because that would mess up the cycling and I don't want to start again. What should I do?
Sorry that I am panicking it's just it took me a while to get perfect cycling and now I don't want my fish to get sick and yet I don't want to start the long process of cycling again.
