However, there are always in demand exotics, for example the sun perch, whose attitude in the garden pond is important now:
Tip 1Sunfish are scientifically named Centrarchidae, family of perch (Perciformes) and subfamily of real perch. The decorative fish are named after their distinctive spiny fins, because Centrarchidae comes from Centrarchus, in Greek "spiny ass" (although the dorsal fin has more spines than the caudal fin.) For pond or aquarium mostly sunfish of the genus Lepomis are offered, namely the common sunfish, Lepomis gibbosus They are also called pumpkin seed perch, because especially the males are noticed by an orange edge on the gill cap lobe (the "ear").
Tip 2Most species have a high physique with flat sides, so does the common sunfish. The dorsal fin has a prickly and a soft-jet part, which usually merge into each other. Most species are between 20 and 30 cm in size, in space-limited attitude they often remain smaller. Especially the male pumpkin-perch are beautifully colored in youth: gray-green back with pearly stripes and yellowish-green to orange color on belly and fins. The whole body has red to orange and blue to emerald swabs. The color decreases with age, it is also dependent on well-being and can adapt to the environment. In addition to the pumpkin perch we also offer other representatives of the approximately 8 genera and 33 species. These species can usually mate with each other, with larger fish than the parent species may arise, which does not necessarily have to be fertile. Who leaves sun fish of unknown origin in his pond, can therefore experience surprises.
Tip 3In any case, all these fish are native to the north of the American continent, but were spread by humans, who used them in foreign waters. In 1877, the sunfish was imported to France, where it was intended to help fishermen catch fish and already populate the first garden ponds. He had reached Germany as early as 1880, and today there are free-living sunfish in Britain, Austria, Switzerland and some southern European countries.
Tip 4With the sunfish you bring ancient forms of life into your pond, the oldest known sunfish already lived in the Eocene, so about 56 to 34 million years ago. There are legends about the intelligence of fish: Some sunfish should recognize their keeper. Less emphatic natures are of the opinion that they rather recognize the food.
Sunfish like well-planted pools, shelters and clean, oxygen-rich, stagnant water. Ventilation is good for them, natural sunlight should enter the pond. If they have enough space, they are quiet fish, which are well tolerated as predators with the same size fish. Especially with large surface swimmers, the close-to-living fish like to share the water. If the pond is too small, they quickly become aggressive and drive everything up close. All sunfish are also sensitive to abrupt changes in water quality or sudden changes in water temperature, and in addition, medicines in the water can negatively affect their wellbeing.
Tip 6As predatory fish, they prefer live food (which can be worms, flies, grasshoppers or water snails), but are also satisfied with dry food or frozen goods. When searching for food, sunfish can also become spawning predators with the water comrades, sometimes they are even used specifically for controlling overpopulation. The solar perch can be problematic in ponds, which should give also amphibians a home, these are usually not equal to the foreign robbers.
Tip 7Most sunfish can hibernate in ponds of some depth, in the winter time they eat little or not at all and otherwise severely limit their activities. They like to multiply in our ponds and are known for their very intensive brood care, which makes breeding possible in the blink of an eye.
Tip 8But exactly this joyous increase is also the problem with the sunfish: each clutch brings about a thousand offspring, with good feeding, the couple spawn several times. However, if your sunfish are slowly taking over the reign of the pond, you should not simply expose it to somewhere. The foreign fish have no natural enemies with us, for good reason, the exposure of fish from the garden pond in free water is prohibited by law and can be punished with fines. On the Internet you can read about how many natural habitats are already endangered by too many sunfish and how many fishing clubs frequently proclaim the sunfish alarm.
If the incalculable robbers, despite their magnificent coloring in the garden pond, are too scary, they populate their pond with indigenous fish, which may also save them from extinction. Incidentally, you could master a sunfish tide by eating the sunfish; in Florida, they are eagerly eaten as "Fried Fish" (even if your children are likely to protest, if they need to get up close and personal, that's tempting the plate has lived before).
