Badis badis, also called the blue perch or blue badis is essentially the most well-known Badis genus and Badidae family. This is a handsome dark-blue fish that has been popular amongst aquarists for a number of dozens of years already.
Blue perch profile
This calm, not demanding when it comes to holding fish, will be attention-grabbing not just for specialists however for starting aquarists as properly.
Description
Based on the newest revision, about 14 Badis sorts have scientific description these days. It appears that these described sorts are only a small part of the entire Badis genus. Each year some new not described species seem. Considering that the genus has a large areal, which turns into more accessible, more discoveries could also be anticipated within the nearest future.
Badis badis is essentially the most well-known genus consultant, whereas scarlet badis comes second on this record.
The blue perch fish resembles dwarf cichlids in its look. The body is relatively low, elongated and a bit flattened from the edges. The dorsal is long, and the caudal fin is rounded. It has a small head and mouth.
The male is about 3 inches long (7-Eight cm) within the wild, whereas the females are 2 inches (4.5-5 cm) long. In the tank, the fish grows a bit smaller.
The body coloring is kind of unstable and changeable. It is determined by tank circumstances, the physiological state of the fish, and its temper. It is very true for males. In a number of seconds, their coloring could change unrecognizably.
Exited males coloring after they have fights between them or throughout the spawning interval look particularly good. The feminine blue perch fish body has considerably less complicated coloring with brown colors prevailing.
Blue perch Habitat in the wild
For fairly a long time, it has been thought-about that Badis badis habitat is proscribed to waters of Central and South India.
However, the research held over the past ten years had broadened their habitat considerably and included lentic waters in South India, Nepal, and Bangladesh (Ganges River basin).
The blue perch species can also be encountered in Pakistan, India state Himachal Pradesh (Yamuna basin), Mahanadi River basin (India state Chhattisgarh), Bhutan, India state Assam (Kaziranga River, Gauhati River, Dibru River).
In the wild, the fish inhabits lentic or slowly flowing waters. In common, Badis badis natural biotope has a low water level, plenty of vegetation, and snags.
A small river in West Bengal, which in some areas will be wade by simply, will be an instance of such a biotope. It has slow water circulate with the next water parameters: t 30°C, рН 6,4, GH 6°.
Blue badis was dropped at Europe at the start of the final century. German aquarists have been the first Europeans to see the fish. Soon it was efficiently bred by them and fashioned stable aquarium inhabitants.

Blue perch Feeding
Blue badis is kind of demanding in this respect. It primarily eats solely small reside meals, and at that very often that is restricted to a blood worm solely. The fish fully refuses to eat dry meals even after ravenous every week.
Tubifex, blood worms, and different maggots will do as reside meals for it. Feeding points very often come up when Badis badis is stored in a standard tank.
Its sooner and more lively tank mates will usually outpace this sluggish fish. If you don’t throw them meals right to their shelters, they will starve and die.
The blue perch fish has fairly a reasonable urge for food. As a rule, it’s not vulnerable to overeating.
Sexual dimorphism
The blue perch fish turns into reproductive somewhat early. Depending on the sort, it occurs by the age of 5-Eight months old. At this age, its size can comprise 2/3 of the estimated one.
Sexual dimorphism could also be seen even when the species will not be reproductive but. The male has a sunken stomach until you feed it, whereas females have more rounded shapes, not that brilliant coloring. Their dorsal and anal finds don’t have sharp endings.
As for the males, apart from their brilliant coloring, giant size, and particular body form, they’ve wider and higher dorsal and anal fins, which they eagerly reveal to their females.
Keeping in the tank
Blue perch is kind of not demanding, and it will get used to any tank circumstances rapidly. The water hardness will be inside 5-20°dH, pH inside 6,5-7,5, water temperature within the range 23-26 °C. In most natural waters, pH level is about 7 or a bit much less, and water hardness is within the range of 3-Four dGH.
The latter are the parameters it is best to attempt to attain solely when breeding the species. Badis may breed in abnormal faucet water with pH not higher than 7.5 and hardness not higher than Eight dGH.
Let’s take into account that the fish species often come from the wild; thus, it’d be logical to maintain tank water parameters like these peculiar to the natural biotopes, no less than at first.
It’s really useful to resume a part of the tank water a few times every week. It’d be higher if the recent water is a bit colder than the one within the tank.
On average, it is best to renew from 10 to 30% of the total tank quantity throughout every week. Due to the large areal, the water temperature within the fish biotope could differ basically.
For instance, in Thailand, water is often hotter than in Nepal. Water temperature within the natural biotopes is determined by the season since in winter it could lower up 15°C, whereas in summer it rises to 25°C or one-two degrees higher.
However, when holding the fish in a tank, the water temperature must be stable. The water flow within the tank must be reasonable and sluggish – for younger species.
It is should have plenty of shelters when holding Badis in a tank. These could also be sick tank vegetation, a pile of stones, or coconut shells, the latter they usually use for spawning.
The benefits of getting numerous shelters in a tank will quickly develop into apparent. The tank dwellers will get used to their new environment sooner. They’ll develop into much less timid and present the most effective of them.
The blue perch fish exhibits more natural behavior in a comparatively small species tank embellished utilizing pastel shades primarily. The tank lighting must be dim because of having fluctuant or long-stalked tank vegetation. In such circumstances, the fish coloring changeability would be the most seen.
There aren’t any particular necessities when it comes to the tank quantity. For one fish couple or one male and two females, a small tank is kind of sufficient.
However, it is best to take into account that chameleon males reveal territorial behavior, and in a small tank, they can’t get together with one another.
A tank for a bigger variety of fish must be spacious and with a number of shelters.
In this case, every male has his personal territory across the shelter he fancies. He aggressively protects the borders and doesn’t let different males shut.
There shouldn’t be too many males within the tank since thus their territories could intersect, which can endanger the lifetime of the weaker species.
The tank lighting must be dim. The tank vegetation flowing on the water floor will give the necessary shadow.
Compatibility
Blue perch is an ideal tank mate for a gaggle of small calm fishes, the place it would take them close to the backside zone. Usually, adult male or fish couple territory is proscribed to a small space close to some shelter they select a coconut shell, a snag, or a flowerpot.
In the presence of comparably sized and peaceable tank mates, which they don’t see as a source of a real or potential hazard, they behave fairly relaxed and swim freely throughout the tank. Thus the observer can see all of their finest coloring and behavior.
Small caves and thick vegetation present the essential feeling of security, and at the same time, they don’t let the fish conceal fully, which is kind of frequent for this sort.
It’s value mentioning that freshwater shrimps (like cherry shrimp) will be the fish prey.
While females swim across the tank finding out all its corners, males invade a small territory close to one of many shelters and go away solely to eat.
Blue perch Breeding
There are plenty of contradictions within the information about breeding. The fish isn’t demanding when it comes to water high quality, they usually can spawn even in water with a hardness of about
20 dGH. However, they really feel higher in water with a neutral or barely acidic response, which was cleaned by the peaty filler.
For holding the fish, the water temperature will be inside 24—27 °C, whereas for breeding, the water temperature must be 28 °C.
As for the shadowing of a spawning tank, which many authors really useful, experience has confirmed that it’s not necessary, no less than before the larvae seem.
The couple participates in the spawning process. It makes use of some strong substrate. Quite usually, the feminine leads the dance.
Her first make an attempt to get nearer to him is taken aggressively, however, she continues her efforts until he responds and embraces her. The couple can spend fairly a long time on this place below the substrate. Then the process begins yet again.
The spawning continues until the feminine lays all of the eggs. During the spawning process that lasts nearly for an hour, the feminine lays about 150-200 eggs.
They are fairly giant (0.8-1 mm in diameter), and it is vitally sticky. It’s nearly unattainable to tear it from the substrate without damaging it. There are only a few underutilized eggs within the clutch; the waste throughout the incubation interval can also be fairly insignificant.
It’s higher to take away the feminine as soon as the spawning is over. The male protects the clutch and the offspring. During this era, he additionally actively adjustments its coloring and surprises with the variety of colors and shades.
Unlike most cichlids and climbing perches, this male can’t be referred to as a carrying father. All his care is proscribed to waving the eggs together with his fins.
The larvae sprout in 40-50 hours, relying on the temperature. They do it collectively for now, not than an hour. The larvae are 2.5-33 mm long, and they’re nearly immobile at first. They could spend hours in the same place.
If the water temperature within the spawning tank is 27—28 °C, in about 6-7 days, the larvae eat all of the yolk baggage, they usually develop into juveniles.
They attempt to swim every now and then. But solely a day later, the juveniles fully get used to the circumstances and start in search of meals.
If by this time the male continues to be within the spawning tank, that is about time to place him away in one other tank. Since some males don’t make it simple when the offspring begins swimming round, they usually attempt to catch them with the mouth and produce them back.
At the identical time, you’ll be able to go away the male along with the offspring for a number of weeks as a result of adult fishes of this sort don’t are likely to eat their offspring.
The juveniles require very small reside meals. They don’t transfer a lot, so to verify they’ve sufficient meals and don’t starve, it is best to put it right in front of them.
Overfeeding is the most important hazard for juveniles. It additionally rapidly results in tank water contamination, and because of this, the entire offspring dies in a short while. For this purpose, water renews and tank cleansing must be completed daily.
In the breeding tank with a sandy backside, reside tank vegetation, a number of snails, and organic filtration, the probabilities of the offspring loss of life get decrease.
The juveniles’ growth tempo can’t be referred to as quick. By the age of a month, they’re barely 1 cm long. After you start feeding them with lower blood worms, they’ll start rising sooner, since they start to maneuver and swim more. There are fewer leftovers, and the process of taking good care of the juveniles turns less complicated.
