What is an Aquarium?

An aquarium is more than just a container for aquatic life; it’s a miniature ecosystem that requires careful management and attention. Imagine a vivarium with at least one transparent side, housing everything from fish to plants. How many of us have ever wondered about the history behind this fascinating hobby?

The Origins of Aquaria

In 1850, Philip Henry Gosse coined the term ‘aquarium,’ combining Latin roots for water and a place. This was around the same time Robert Warington developed the aquarium principle, explaining that plants could produce enough oxygen to support animals in water tanks. Can you imagine how revolutionary this concept must have been back then?

The First Public Aquarium

Gosse took his passion for aquatic life a step further by creating and stocking the first public aquarium at the London Zoo in 1853. He published a manual on aquariums the following year, detailing how to maintain these miniature ecosystems. How many of us would have thought that such a simple idea could lead to so much complexity?

The Evolution of Aquaria

In the Victorian era, ornate aquaria appeared at the Great Exhibition, and their popularity soared after Gosse’s creation. Tank designs evolved over time, with glass-fronted aquaria becoming popular in the 1850s. Germans soon rivaled British interest, publishing articles about saltwater and freshwater aquaria. In the United States, books like ‘The Family Aquarium’ (1858) and ‘The North American Review’ (1876) were published, and the first aquarist society was founded in New York City in 1893.

Modern Aquaria

The 20th century brought significant advancements. The mechanical aquarium air pump was invented around 1908, powered by running water instead of electricity. Electricity allowed for artificial lighting, aeration, filtration, and heating, making the hobby more accessible to amateur aquarists. Exotic fish species became available, and plastic shipping bags made it easier to import them from overseas.

Materials and Designs

Glass aquariums were developed in the 19th century and became popular due to their aesthetic appeal. The modern style of silicone-sealed glass aquaria replaced metal-framed designs until the mid-1960s. Acrylic aquaria became available in the 1970s, offering strength, lower weight, temperature insulation, and unique shape possibilities. Today’s aquaria consist of glass panes bonded together with silicone sealant and plastic frames attached for decoration.

Other Materials

Larger aquaria use stronger materials like fiberglass-reinforced plastics, reinforced concrete, or plywood. Plywood offers lower construction costs, less weight, and better insulation. Imagine the challenges of designing an aquarium that can house entire ecosystems!

The Aquarium Hobby

Aquariums range from small glass bowls to immense public aquaria. Relatively large home aquaria resist rapid fluctuations in temperature and pH, allowing for greater system stability. Small aquaria should contain at least two forms of filtration: biological and mechanical. Chemical filtration is frequently achieved via activated carbon, filtering medications, tannins, and other known impurities from the water.

Types of Aquariums

Biotope aquariums recreate specific natural environments like freshwater habitats or saltwater coral reefs. An aquarium can range in size from under 1 litre to over 6,300,000 US gallons. Combined biological and mechanical filtration systems convert ammonia to nitrate or phosphate.

Maintenance and Care

Daily maintenance involves checking water quality and fish condition, while weekly changes typically involve replacing up to 30% of the water, cleaning gravel, and removing food residues. To use tap water safely for aquariums, it needs to be treated with a water conditioner that removes chlorine, chloramine, and heavy metals.

Water Conditions

Water conditions are crucial and can be affected by solute content, salinity, pH, hardness, dissolved organic and gas content, among others. Aquaria may have freshwater, brackish, or saltwater environments, with different requirements for each.

The Nitrogen Cycle

Maintaining the nitrogen cycle is crucial for an aquarium’s inhabitants. Fish and other organisms excrete waste in the form of ammonia, which must be removed through the nitrogen cycle or passed through zeolite. A well-balanced tank contains nitrifying bacteria that metabolize ammonia to nitrite and then nitrate.

Filtration Systems

Effective filtration is vital to maintaining balance. The biological load (bioload) refers to the burden placed on the aquarium ecosystem by its inhabitants. High loading can upset equilibrium. The bioload depends on aquarium size, including oxygen intake and bacteria colonization space.

The Future of Aquaria

As technology advances, so do our methods for creating and maintaining aquaria. From mini or nano aquariums to large public displays, the possibilities are endless. The hobby has strong followings in Europe, Asia, and North America, with research showing that observing aquatic life can have numerous health benefits, including stress reduction and improved mood.

Whether you’re a seasoned aquarist or just curious about this fascinating world, there’s always something new to discover. From the simple beauty of a glass bowl to the grandeur of public displays, the aquarium hobby continues to captivate and inspire us all.
