Fancy goldfish are beautiful fish, but they produce a huge amount of waste and require stronger filtration than many people realize. In this aquarium maintenance video, I upgraded a struggling goldfish tank’s filtration system, improved circulation, and cleaned out heavy buildup to help create a healthier, more stable environment long-term.

Goldfish are not bowl fish. Learn the proper goldfish tank setup, why bowls cause problems, and how to keep your tank clean and your fish healthy.

Life in the goldfish tank has been so sweet lately. Cocoa, my little rescued Black Moor, has been spending lots of time side by side with Topaz, my bright orange Fantail.
