Goldfish & Algae

One of the main downfalls about caring for a goldfish is the growth of algae that appears in the aquariums. Algae is that green gunge that grows inside the tank, usually as a green layer on the glass, this can happen mush faster if your tank is getting a lot of sunlight. It is not harmful for your fish, but it really does take away the visual appeal of a goldfish tank, if left it will get so bad that it will cover the entire glass on the fish tank.

Cleaning the Tank

You can buy tools in the pet shop that a similar to a scraping tool, like a razor blade on a stick, you use this to scrape off the algae from the inside of the tank. Also available are cleaning magnets, one magnet sit on the out side of the tank, the other on the inside that has a special abrasive pad on one side. The magnets are held together through the tank and the outside one is dragged around, moving the inside magnet with it, thus cleaning the tank.
