Why did my fish die, please help (Pics) :(?
First, I am sorry for the loss of your fish, you clearly were doing everything you can to give him a happy life. Sadly, Nutrafin and other products that promise to cycle the tank don’t always work. They are a good support for a new tank, but they don’t complete an instant cycle. I don’t know why they are allowed to keep promoting it that way. There is a link to a great discussion where someone tested a similar product out and you can see how it helps, but doesn’t do it instantly: http://www.tetra-fish.com/forums/showthr… But, being in the new tank for 24 hours should not have created cycle problems so quickly. It is more likely the sudden water change may have been too much. Did you float him in a bag? Was the water the same temperature in both tanks? Sudden changes in water temp can really affect a fish, as can sudden changes in water pH. It could be the fish was sick/stressed any
