Butterfly Koi Introduction
by: Jiyong Park

The Butterfly Koi is not a new species or type of Koi. But it is extraordinary since it has a specific attribute - it's none other than its fins and tail. The Butterfly Koi is immediately becoming trendy numerous Western countries. Here is how they came about.

It was the first Koi that produced Carp such as the German and Asian Carp by breeding it.. After years of selective breeding, different color mutations began showing up. As early as 1805, the first color patterns were recorded. At present, there are literally thousands of color variations existing. The most widespread colors found are green, white, yellow, red, silver, black, orange and blue. Mixed with the patterns available, the probability are almost unending. Each noticeable pattern and color has their own names, which are most often as extraordinary as the color they are referring too. Favored types vary by country and location.

Just about 30 years ago, Koi breeders took some Koi and mixed them with the Asian long finned carp. They did so to try to nurture a type that would be more enduring and less prone to virus and ailment because generations of inbreeding has caused the Koi to grow to be quite fragile. The outcome of their interbreeding was a type of Koi that nobody elsehas seen beforehand. It had long fins and tails and over the years showed immense resistance towards disorders. This type of Koi was at a later time called the Butterfly Koi.

The Butterfly Koi at present is found universally alongside its normal cousin, the Koi. They also come in assorted varieties like Asagi, Kohaku, Showa etc and are recognized to be the most pretty of all Koi because of their elongated fins and tails.

Koi, including the Butterfly Koi, unlike most other fish will keep on to grow until they attain their breeds' dictated size, no matter the location that they are in. Usually, the baby koi can be as small as 3 inches.. On the other hand, a large Koi have even been known to reach lengths of three feet or more. The most known size found is around two feet in length.

Koi are omnivorous fish, which means they will eat both meat and plants. This means that their diets are very resourceful and they will eat pretty much anything.

Koi are non-aggressive fish. This means that they are convenient to live with other fish such as goldfish or comets. The only issue you may acquire is less important, not as much of able fish may possibly languish from lack of food, as Koi are fast eaters. Koi are so gracious that they can be disciplined to eat out of their owners' hand. Koi do not have teeth, so you will not get bitten if you intend to feed your Koi out of your hand.

Apistogramma, Dwarf Cichlids In The Aquarium

Apistogramma, Dwarf Cichlids In The Aquarium
by: Auke veenstra

The real apistogramma's come from southern America, they all have the same characteristics, like a complex breeding behavior, as their large relatives, only their size is different. Besides the apistogramma group there are also some relatively popular dwarf cichlids from Africa, like the Pelvicachromis group. From this group the most widespread cichlid is the Pelvicachromis pulcher, also known as the Kribensis or Purple cichlid.

Generally the cichlids from the apistogramma group are more fragile and harder to maintain, and breed, for a longer period of time. In my opinion apistogramma's are not real beginner species. They are more likely to get diseases if not all the environmental variables are properly taken care of. They need soft and acidic water with a low PH value, a PH of 5.5 to 6 is preferable. They hardly eat dry foods, best is to feed them live foods or frozen food, like bloodworms, brine shrimp and mosquito larvae. Apistogramma species can be kept in a large tropical community aquarium, but be sure the other fish are not too small, they can defend their territory very fiercely, and can be quite aggressive when they are breeding. In my opinion it is best to keep the apistogramma's on their own, in a larger aquarium you could combine two apistogramma variants together, maybe supplemented with a small group of other fish, like some livebearers or betta's. They also can be kept together with discus or angel fish. I always have a harem of apisto's in my discus tanks, just to populate the lower areas of the aquarium and I really like these small dwarfs with a big attitude.

The cichlids from the Pelvicachromis group are much more tolerant when it comes to water values and feeding, I do consider these cichlids a good beginner species. They are hardened, beautiful colored and eat almost anything. The Pelvicachromis pulcher is maybe one of the most easy to breed cichlids as well. If you have an adult couple they will reproduce, in a community tank, a special species tank or in a pond, some people like to breed them in their pond during summer. Actually some of the biggest and nicest colored Pelvicachromis pulcher were pond bred and raised. The only thing to keep in mind with these cichlids is that they are capable of redesigning your aquarium, they can make huge holes and are real little bulldozers. So if you have, or want to setup, a subtile planted tank, don't add a couple of Pelvicachromis to your aquarium.

The last dwarf cichlid I want to mention is the Microgeophagus ramirezi, or Ram cichlid. Their behavior and care are roughly the same as the apistogramma's but they are more tolerant when it comes to water values, and in my experience they are easier to keep in good condition. Unlike the apistos they have to be kept as a couple, not a harem but that's the only breeding experience I have. I have tried several couples, have a couple in a breeding tank right now, but I have never even had a clutch of eggs. I know from other breeders that they are kind of hard to get going, but if they do they never stop.

Attracting Zoo Plankton Catches Fish! Underwater Fishing Lights Details Here!
by: Mark Fleagle



Night fishing for any species of fish can be very rewarding and exciting. However, there is some specialized night fishing equipment you will need to have to be successful. We are going to talk about the use of night fishing lights today.

Some of the more common types of night fishing lights that are available on the market today are a variety of different 12 volt fishing lights such as underwater fishing lights, and floating fishing lights, which both have very important purposes.

Underwater 12 volt fishing lights come in a variety of different shapes and sizes but the most common size is the 4ft fishing light. They also come with different colors and power ratings. The best underwater fishing lights will have a wattage rating of 25-40 and generate about 1000 to 3000 lumens. The illumination color that seems to work the best is green. These lights are important because they are necessary to attract zoo plankton. You are probably asking yourself "what is so important about attracting zoo plankton" Well the answer to that question is very simple. Attracting zoo plankton will attract bait fish close to the area you are fishing. If you know anything about the food chain of most game fish, (which I know you do or you wouldn't be reading this page now) bait fish are the primary food source of the most of the game fish you will be targeting at night. If you can put a submerged fishing light under the water and start catching fish, well that's a no brainer! Of course you will do it. If you are like me, any tool that can help you catch more fish, id going to be part of my fishing equipment, and night fishing lights are important.

Floating fishing lights have a similar purpose to the underwater fishing lights. A floating fishing light will attract and concentrate bait fish that are coming to the area. Game fill will also be attracted to the lights. Game fish will normally lay in waiting just outside the beams rays of both the floating fishing lights and the underwater fishing lights, waiting for unsuspecting bait fish to wonder outside of the beams rays, or often they will dart in and catch a bait fish and dart back out to there hiding area. Many times the bait fish do not even suspect that the game fish are even around. Floating fishing lights are also classified as 12 volt fishing lights, and can be powered by any 12 volt battery source. My personal preference is to use a car battery. I power both my floating fishing lights and my underwater fishing lights from this power source. A fully charged car battery will last me a full last me all night. I than recharge the battery when I go home. Both underwater fishing lights and floating fishing lights normally come with alligator clips and makes hooking them to the power source very simple.

If you want to have a exciting fishing experience you need to try night fishing. You may be pleasantly surprised at how many fish you can catch. Also if you want very little fishing pressure you will love night fish.
