The Impressive Black Koi By Jack Fromwell

If you're looking for something new and exciting to add to your existing fishpond or are contemplating building a new one you should consider the Koi species of fish. They make an exciting and entertaining addition to your fishpond.

The Koi species of decorated carp come in various colours and patterns. Black Koi are similar to other varieties with the exception of their dark pigmentation and not much else. Koi are long-lived fish and can survive for as long as 200 years, but the normal expected lifespan should be between 25 and 35 years. Koi are regularly viewed in outdoor ponds all around the globe. The distinction between Koi males and females can easily be recognized by the males' concave anal section. On occasion the males also display breeding spots on the head. A Koi female can lay as many as 1000 eggs during one mating season. Immature Koi are referred to as fry and will start hatching in about four to seven days, depending on the variations of the water temperature. Koi pigmentation will not be displayed until the immature fish are between three to twelve weeks of age.

The Japanese people initially took carp mutations to breed these colourful fish. The colour selection was minimal at the start of this process, with only two colours being attained. More selective breeding of Koi produced different colour varieties and combinations of patterns.

Black Koi can reach an impressive 36 inches in length. Because of their length, large ponds are the most suitable way to keep all Koi including Black Koi. One of the first Koi black mutations was the Magoi Koi that also came with the ability to grow to a very large size. When closely looking at a Magoi Koi they appear black when viewed from above, but are actually deep bronze in colour. Magoi Koi DNA is now being reintroduced into other species because of the potential involved in increasing the size and to hasten the growth rate of a new species.

The Karasu meaning "crow" in Japanese was one of the initial species of Koi produced. The normal coloration of the Karasu is a fish that has both black fins and a black body but with a variation that can also have a white or orange belly.

Environment and diet have a tendency to change the colour of the Koi. The variations will make the fish appear a duller or brighter shade of pigmentation. Matsukawabake Koi has the adeptness to change colours. It's a Koi that is black in colour and has patches of white on its body. One of the amazing things about this Koi is that it can completely change its color according to the temperature of the water or the seasons of the year. This fish can actually change from totally black to totally white, but when the conditions return back to normal so will its original patches and colours.

A more recent Black Koi species the Kumonryu first appeared in the 1980s. It's the most popular Black Koi species and the name means Dragon Fish. This species received its name, because of the similarities of the bodies of dragons depicted in ancestral paintings. They also have the ability to change colours, like other species of Koi.

Koi come in a large variety of colours, and owning and raising these fish with the chameleon like ability of changing colours before your eyes, pond owners are naturally attracted to these beautiful fish. All of the above species of Koi would make a beautiful addition to your new fishpond.

Six Things to Avoid As a Newcomer to Marine Reef Keeping By Gareth P

So what should you avoid when keeping a reef aquarium when new to this fascinating hobby?

Lack of knowledge. This is very important, you should learn as much as possible before even thinking about buying anything. Books are expensive, but there are many other Articles and Informative Forums on-line packed with information and help.

Hard corals. These should be avoided until a full understanding of water chemistry and a confidence in maintaining these levels are achieved. These corals require more intense lighting requirements and feeding. Compatibility also creates issues too. As above really, learn about water chemistry, then research your coral selection carefully.

Expensive unnecessary equipment. As a newbie to Reef Keeping it is totally unnecessary to purchase Computers, Reactors, Top up devices, and any other fancy items that may arise. I say this because as a new Reef Keeper you need to understand and manage a Reef Aquarium. Having fancy computers and reactors will create loads of confusion. The same can be said about Calcium Reactors and so on, with issues such as overdosing.

Fancy expensive fish. Please walk before you run. There are loads of reasonably priced fish available, many colorful and rewarding too. Imagine how upset you would be to loose a expensive fish and think of the impact on the environment. Conservation is key to this hobby.

Overstocking. Don't rush out and buy everything you see and like, you will overload your aquarium and most likely kill your new livestock. Do it slowly and stock fish according to your aquarium size.

Overfeeding. This is something many get wrong. By overfeeding you are creating your livestock to produce more waste, Resulting in higher nitrates. Feed small amounts only when required.
