A nano-aquarium - that is, a small-volume aquarium - requires special attention because decline in water quality and increased fish stress levels change in inverse proportion as tank sizes become smaller. Two aquarium experts tell hobbyists everything they need to know about setting up a miniature aquarium. These manuals make great introductions to the pleasures and duties of pet ownership for inexperienced and soon-to-be pet owners, as well as for older children having their first experiences with pet care. Attractively illustrated and filled with helpful information, these books advise on purchasing, housing, feeding, health care-and where applicable, grooming and training pets. Each book is individually written by an expert-a trainer, breeder, veterinarian, or other animal specialist. "Barron's Complete Pet Owner's Manuals" cover every popular dog and cat breed, as well as bird varieties, hamsters and other small caged animals, fish varieties for aquarium hobbyists, terrarium pets, and even exotics, such as reptiles, amphibians, and scorpions.
