What is fish health?

Defining the concept of ‘health’ can be very tricky, generally, animals are considered ‘healthy’ if they are free from disease, however, disease is itself defined as a state of ill health!  These circular definitions can lead to confusion so perhaps a closer look at the causes of ill health in fish may help to hone any definition of health

Spotting ill health in your fish

In order to recognise a poorly fish, we must first know what a fish looks like and how it behaves when healthy. We can only recognise the ‘abnormal’ when we know what is normal.

For example, a goldfish keeper may become concerned about the presence of small white spots on the gill covers and pectoral fins of their fish. Further investigation will lead them to discover that these small white spots are not a sign of disease but are actually special spawning pimples that cover certain parts of male goldfish at spawning time.

Aquariums as design elements

Decorate your home with an aquarium

Home aquariums are real eye-catchers and look particularly good in living rooms. More than just a habitat for fish and other underwater creatures, an attractive aquarium tailored to the look of your living room will enhance your interiors and turn visitors’ heads. They also exude a feeling of calm, creating an inviting, cosy atmosphere. There are many ways to design an aquarium and make it a beloved, high-quality and modern addition to your home.

Phosphorus and your Aquarium

Aquatic animals and plants held in ponds or aquaria will have a significant effect on the chemical composition of the water. One of the major trends that can be expected to occur in aquarium or pond water is the accumulation of waste-derived chemicals. These may be in the form of toxic compounds such as ammonia which must be converted into a non-toxic form or non-toxic compounds such as phosphate which can still cause other problems by encouraging the growth of unwanted algae.

Phosphorus is a vital biochemical. It is part of bones (calcium phosphate), it is found in the subunit molecules that make up DNA and is found in numerous other vital biochemicals. Plants commonly contain 0.05 – 0.5% of their dry weight as phosphorus and fish usually contain a figure of 2 to 3% phosphorus or more. Phosphorus usually occurs in animals and plants as phosphate (PO43-).

Aquariums are good for the soul

Science has now confirmed what fishkeeping fans have known for some time: watching fish, shrimps and so on in their underwater world is relaxing and promotes well-being. Standing by a gently babbling river, watching the water or gazing out over a favourite landscape – again and again, studies confirm that calm moments in nature help people to relax.

Researchers at the National Marine Aquarium in Plymouth have now proven that aquariums – and the fish that live in them – offer the same form of relaxation. Its huge tanks have been pulling in the crowds for a long time now. When one of the tanks was restored and gradually filled with new aquatic creatures, the scientists seized the opportunity to conduct a small study.

Fish transport and acclimatisation

At a time when the use of plastic bags is being reduced it is worth considering one utterly vital role that the plastic bag performs in the aquatic trade: the transport of live fish.

Plastic bags are water and air-tight, they are available in a range of shapes and sizes to suit a huge variety of fish species and they are cheap and simple to produce. Without the humble plastic bag, international transport of live fish would be much more complicated and hence expensive, with these costs ultimately being borne by the hobbyists.

Keeping fish as pets

The time comes when every child wants a pet of their own. After all, children love animals. But not all animals are suitable for all families. For example, you might rent an apartment where you are prohibited from having popular pets like cats or dogs, or you may have a family member who is allergic to animal hair. Fortunately though, there are other animals that can fulfil your child’s desire for a pet. In fact, fish are becoming an increasingly popular choice as a pet. They are among the oldest vertebrate animals in the world and offer lots of advantages.
