me and my sister and my friend cought a littel fish from the lake.weput it in a tank when we got home it stade alive for 2 days and the next day it died why did it die?
the new environment was probably not close enough to the environment it left. The tank's PH was probably bad and other things.
It sounds like you didn't research fish well because fish are very delicate and can easily die because the water temperature is too cold or it was stressed from not getting to stay in its original home.
If you want a fish, research them well and then get one from the pet shop.
well first off if the tank wasn't cycled bad water conditions would have gotten to it also wild fish get stressed a lot when put into a tank so it could have been a combonation of the stress and the water conditions
