Hello, and welcome to the ever-wonderful field of aquariums. Thank you for allowing me to share with you the basics of goldfish care. You will find that though they've been human pets for centuries, and often referred to as ''easy to keep,'' modern Goldfishes are quite different than commonly perceived. These minnows require a good deal more room than bowls can provide, attention to filtration, restraint in not over-feeding, and regular upkeep of their systems water quality. Not to worry; all will be revealed here.
