Aquarium upgrade from 3 feet to 4 feet without loosing any fish

Published 2021-07-21
I have upgraded my aquarium from 3 to 4. I was concerned about shifting fishes to an entirely new aquarium and was worried how my fishes going to adjust in it. I used the used sponge of my old filter and left the aquarium overnight with filter on. Next day I shifted my fishes and all are doing good now.
