How to Breed A Livebearing Fish

 

 Copyright © Practical Fishkeeping

Just started keeping fish? Fancy breeding some? Aquariums And Fishes introduces you to some tropical’s which take zero encouragement to get frisky!

You've just set up for tropical fish and your tank is either cycling or just cycled. First fish would have typically been half a dozen Zebra danios, all doing well, and soon your shop will allow you to stock a few of the species you really took up the hobby to keep - the colorful ones.

High on your list will be guppies, Siamese fighters, angels and Neon tetras. Why they aren't a good idea to keep together is the subject of another article, but if you do get your hands on some guppies, platies, mollies, Swordtails or Endler's, you will more than likely start to breed them.

Life in a Fishbowl: The Science and The Art of Fishkeeping

My First Aquarium:

How many times has this happened to you? You go to a local carnival and play that game where you try to throw ping-pong balls into little brandy glasses on a table. If your ball gets into one of those glasses, you win the prize - a bright orange goldfish swimming around in a tiny cup of water. So, you take the fish home in a plastic bag and when you get to the house you realize that all you have to put it into is a large mayonnaise jar. You wash out the mayonnaise jar, fill it with cold tap water and pour the fish in. Now it's swimming around in the jar as happy as can be!! You might even add some bread to give it food, but you notice it is not eating. It's getting late so you go to bed wishing the fish "good night". The next morning you find what typically happens to thousands of these ping-pong carnival goldfish each year: it's now swimming near the top of the water and slowly gasping for air. It is definitely not looking healthy! To make matters worse, the bread you had put into the jar the night before is all soggy and the water is turning cloudy. A few days later, the fish is floating belly up with a wide goggle eyed stare, quite dead to say the least!! I really wonder how often this story repeats itself across America!

My Introduction to Science:

I've been interested in fish since I was five years old and I regret to say that I've been guilty of the very scenario described above numerous times in my life. But, over the years, my fascination with fish and aquariums has led me to learn a lot about the art of fish keeping and the science that goes with it. In this article I'd like to discuss with you some of the aspects of fish keeping and how this hobby relates to scientific disciplines as chemistry, animal physiology, biochemistry, field ecology and even microbiology. For convenience this article will only discuss freshwater systems.

LED Lighting For Public Aquariums

PUBLIC AQUARIUMS & ORPHEK LED LIGHTING

Public Aquariums have been connecting people with the Natural World since 1853 when the first Public Aquarium was opened in London. Today, visiting a Public Aquarium is not only a family entertainment, but also an opportunity to learn about animals, plants, and ecosystems, including the preservation of species and environmental responsibilities, as Public Aquarium’s mission and objectives have broadened to include programs and projects of education & research; preservation, rescuing & rehabilitation and breeding of animals and plants.

Although in these last three decades many technology developers focused on technical solutions to cover all aspects of aquarium construction, operation and breeding, Public Aquariums face challenges on daily basis such as:

Opportunities for Public Aquariums to Increase The Sustainability of Aquatic Animal Trade

The global aquatic pet trade encompasses a wide diversity of freshwater and marine organisms. While relying on a continual supply of healthy, vibrant aquatic animals, few sustainability initiatives exist within this sector. Public aquariums overlap this industry by acquiring many of the same species through the same sources. End users are also similar, as many aquarium visitors are home aquarists.

Here we posit that this overlap with the pet trade gives aquariums significant opportunity to increase the sustainability of the trade in aquarium fishes and invertebrates. Improving the sustainability ethos and practices of the aquatic pet trade can carry a conservation benefit in terms of less waste, and protection of intact functioning ecosystems, at the same time as maintaining its economic and educational benefits and impacts. The relationship would also move forward the goal of public aquariums to advance aquatic conservation in a broad sense.

For example, many public aquariums in North America have been instrumental in working with the seafood industry to enact positive change toward increased sustainability. The actions include being good consumers themselves, providing technical knowledge, and providing educational and outreach opportunities.

10 Largest Public Aquariums in the World

The most common size for a home aquarium tank is probably 29 or 30 gallon, though some aquarists have constructed aquariums of many thousands of gallons. Public aquariums can be dramatically larger than any home aquarium. But only a few public aquariums are big enough to make it to our list of largest aquariums in the world. These kinds of aquarium can hold whale sharks, and manta rays. It takes a very large tank to hold these kinds of aquatic creatures.

In order to compare these large aquariums we have looked at the size of their biggest tank (in gallons). Most aquariums have several tanks and the combined volume of water can be much larger but it is only the largest aquarium tank that is counted. So here’s a list of the largest aquariums in the world.

Aquarium of Western Australia (0,8 million gallons)

 

Located in a coastal suburb of Perth, the Aquarium of Western Australia, or AQWA in short, contains Australia’s largest aquarium tank. The aquarium’s main tank is 40 meters (130 ft) long and 20 meters (66 ft) wide and holds 3,000,000 liters (793,000 gallons) of seawater. It incorporates a 98 meter (322 ft) underwater tunnel. For a fee, snorkelers and divers can get even closer to the fish, sharks, and rays by joining the aquarium’s dive master in exploring the main tank.
