CHARACINS




LEBIASINIDAE FAMILY
The Lebiasinidae Family is found throughout South America and is made up of the genera, Copella, Nannobrycon, Nannostomus, and Pyrrhulina.
SIZE : The Lebiasinidae Family includes mostly small to medium sized fish, usually not more than 5".
S: The fish of this family usually swim in the middle to upper water levels.
TANK : The tank should be at least 20" (50 cm) long or 10 gallons (38 l).  Most need well-maintained water free of nitrates and nitrites.  The tank should be arranged in dark colors and have floating plants to diffuse the light.
WATER : These fish can tolerate a pH from 5.5-7.5, but prefer slightly acidic water. They prefer soft water ranging from 1-10 dH, and require a temperature of 72-82°F (22-28°C).
SB : The Lebiasinidae Family are peaceful, timid fish that can be combined in a community tank with other small, calm fish. During the day they hide, but at dusk they become active, and search for food.
SC : Tetras, Corydoras, Loricarids, Killifish, Apistogramma .
FOOD : Small live, dry, and frozen foods are recommended. These fish should be fed in the evening.
B : A breeding tank with a single pair is recommended. A mesh netting or a substrate of layered marbles should be used, for these fish will eat the eggs and young. Best results are accomplished when the pair is removed after eggs are laid. The water should be soft, around 1-3 dH, while the pH should be around 5.7-6.0. Feeding the pair Drosophila or black mosquito larvae may help stimulate spawning. The number of eggs produced varies greatly on the species; laying between 1 and 100. The eggs fall to the bottom or stick to plants and hatch, depending on the species, in 1-4 days.
BP : Fairly difficult. Spawning is often hard to initiate.
R : The coloring of many of these fish changes radically from day to night.
DC : These fish in this family need to be kept on a regime of constant water changes.  They are somewhat sensitive to changing water conditions and water pollutants.
 
Splash Tetra, Jumping Characin, Spraying Tetra [
Copella arnoldi
SYN : Copeinaarnoldi
PD : The Splash Tetra has an elongated body.  The body color is olive green to brown and the belly is white. A stripe, slightly darker than the body color, extends from the gill cover to the caudal fin.  A thin copper-colored line runs right above the darker band.  A black band extends from the snout, through the eye, and to the gill cover. In favorable water conditions, the upper half of the iris will develop an iridescent  orange color. 
SIZE : Males to 3.5" (9 cm), females to 2.8" (7 cm)
SS : Plain Copella ( Copella nattereri ), Half-striped Pyrrhulina ( Pyrrhulina laeta )
HAB : Near the banks of slow-moving rivers with heavy vegetation.  South America; in Guyana, and the Rio Para.
S: middle, top
TANK : 20" (60 cm) or 10 gallons (38 L).  The tank should be well-planted and have a cover of floating plants. Position the tank in a place where it will receive morning sunlight.  Use a tight-fitting cover as this fish is a jumper.
WATER : pH 6.5-7.5 (6.8), 2-12 dH (6), 77-84°F (25-29°C)
SB : A peaceful fish that can be kept in pairs or schools.  Does well in a community tank.
SC : Tetras, Corydoras, Loricarids, Killifish, Apistogramma .
FOOD : Live, small flying insects, insect larvae, brine shrimp; flakes.
SEX: The males are more colorful, larger, and have more elaborate fins.
B : This species is popular because of its peculiar spawning habits.  This fish can be bred in small tanks(16" or 5 gallons). The water should be soft and slightly acidic, with the water level several inches lower than normal (4-8"). The pair should be fed live foods, such as those suggested in the introduction of this genus. The pair will jump against an overhanging leaf or the tank glass, and press their bodies together.  About 8-10 eggs are laid on the object. This process is repeated until 150-200 eggs are laid.  The male engage in brood care by splashing water on the eggs every 10-15 minutes. After 30-40 hours the eggs hatch and the fry drop into the water.  The parents should be removed at this time. The fry are very small and should be fed small live foods.  This spawning habit most likely developed from a large amount of predators that can be found in this fish's natural habitat. The eggs are sometimes laid on the underside of the tank lid.
BP : 6. Breeding is fairly easy in a properly, set-up breeding tank. 
R : Does best when regular water changes are performed. 
DC : 3. A hardy fish whose colors will only fully develop in a well-maintained tank.
 
Golden Pencilfish, Beckford's Pencilfish [
Nannostomus beckfordi
SYN : Nannostomus anomalus, N. aripirangensis
PD : This elongated fish, varies greatly in color depending on the geographical location from which it originated. A thick, dark band extends from the snout to the base of the caudal fin.  The tall dorsal fin ranges in color depending on the fish's body color. 
SIZE : To 2.5" (6.4 cm)
SS : One-lined Pencilfish ( Nannobrycon unifasciatus ), Dwarf Pencilfish ( Nannostomus marginatus ).
HAB : Thickets of shallow vegetation in small brooks and creeks. South America; French Guyana,Guyana, and Brazil in the Rio Negro and middle Amazon.
S: middle, top
TANK : 20" (50 cm) or 10 gallons (38 L).  The tank should be well-planted with fine-leafed plants (possible spawning site) and have a partial cover of floating plants to diffuse the light.  Arrange the tank in dark colors with dark gravel. This fish prefers clean, peat-filtered water.
WATER : pH 6-7.5 (6.7), dH 1-18 (5), 72-81°F (22-27°C)
SB : A peaceful fish best kept in schools.  Combine with other peaceful fish including small characins and catfish. Unlike other species in this family, Beckford's Pencilfish can be combined with more lively fish. Males often battle with each other, although neither fish is ever injured.
SC : Tetras, Corydoras, Loricarids, Killifish, Apistogramma , Discus, Hatchetfish, Rasboras,Danios.
FOOD : Live; brine shrimp, bloodworms, glassworms, Tubifex , mosquito larvae, Cyclops, Drosophila ; also takes dry foods
SEX: Males are slimmer with brighter red colors.
B : Use a small tank with a pH from 6.0 to 7.0, soft to medium water (1-6 dH), and a warm temperature of 82-86°F (28-30°C). Place as many fine-leafed plants as possible in the tank along with Java moss. The lighting should be dim. Spawning is initiated when the male pokes the female's abdomen.  Pencilfish are notorious egg-eaters and often eat the eggs are they are dropped.  Try using a pipette to suck up the eggs, before this occurs. Remove the pair or the eggs to a rearing tank.  The transparent eggs hatch in 24-36 hours and the fry are free-swimming after 6 more days. At this time, the fry swim near the surface of the water and should be fed with rotifers, newly hatched Artemia, and powdered foods.  When the young begin to swim at a lower water level, they can be fed larger foods. With frequent partial water changes, the young will grow quickly, even beginning to develop adult colors as soon as five weeks.
BP : 5. Breeding is fairly easy as long as the eggs are separated from the parents in time.
R : Beckford's Pencilfish occasionally has problems with acclimation.  It is normal for individuals to be shy and lose color for the first weeks in a new tank. There are several different color forms available.  The color of this fish greatly depends on its geographical habitat. Several sub-species have been described.  Beckford's Pencilfish is the easiest of its genus to care for and breed. When excited, the colors of this fish are intensified.
DC : 3. A hardy, peaceful fish ideal for small community tanks.
