Aquarium Fish Disease

This can happen when you do not do the proper maintenance in your tank, overload your tank with fish, or overfeed your fish.Your aquarium can also be subjected to disease from the fish that you put in it. Fish that you buy in the pet store may already be harboring illness or disease before you even take them home. Even if the fish don’t look sick they could still be on their way to getting sick and infect the whole tank. So when you buy fish be sure to inspect all the fish in the aquarium to ensure that they all look healthy, not just the one you are purchasing.
