Nannostomus anomalus Popular name Anomalus Pencilfish, or Golden Pencilfish Origin Amazon Basin. British Guiana. Size 1 to 1 3/4 inches. appearance The elongated body has a golden-brown tint and is traversed by alongitudinal black band edged with gold and someimes with red. At night the horizontal band fades and dark bands or blotches appear on the sides. Behavior A peaceful fish suitable for the community tank; hardy in spite of its delicate appearance. Water conditions Moderately soft to moderately hard, near neutral to slightly acidic water. Temperature 80°F. Sexing The plump shape of the female is the main guide. Breeding This is one of the easiest aquarium fishes to breed. It does not destroy its eggs or young. It can be bred in the usual Characin fashion but the number of young produced is likely to be small. A simpler method is to place three or four females with two males in a well-planted tank or a tank containing a fair amount of some artifical spawning medium, and feed them well. The tank will soon be seen to contain many (50 to 100) young fry in various stages of development. Either the adults can now be moved to a fresh tank or the fry ladled out and reared elsewhere.

Popular name Pearl Headstander. Origin Northern South America. Size 3 inches.Appearance The elongated grayish-green body is covered by rows of brown spots. The fish swims head down at an angle of 45° from the horizontal. Behavior Very peaceful; can be kept in community aquaria. Feeding Eats all foods but must be provided with fresh green foods such as lettuce and spinach. Water conditions Moderately soft, slightly acid water. Temperature 80°F. Sexing Females plumper than males. Breeding Has been seldom bred. Method same as that described for othet Characins. About 150 to 200 brownish eggs are laid. Fry difficult to rear. Recommended feeding system Aquaze tropical.
Origin South America. SlZe 6 inches. Appearance A rather startling fish with a long cylindrical body and pointed snout. The body is traversed by longitudinal strips of black and gold; a red spot on the root of tne caudal fin which leaves the lobes colorless completes the bizarre color combination. Behavior Swims in a head-down fashion but straightens up when it darts forward. Can be kept in company with other large fishes. Feeding Mainly live and frozen foods supplemented with green foods such as lettuce. Water conditions Not critical. Temperature 78f.Sexing, Breeding Not known. Recommended feeding system Aquaze tropical.
Popular name Redspotted Copeina. Origin Central Amazon. Size 4 inches. Aquarium specimens up to 5 inches. Appearance Not as elegant or streamlined as C. arnoldi. It has a bluish silvery body and yellowish fins with orange-red margins. Behavior Reasonably peaceful, but it is rather large for the average community collection. Feeding, Water conditions Same as C. arnoldi. Sexing The male is more colorful than the female. It also shows rows of tiny red dots on the flank. Few or no such dots occur on the female. Breeding This is another Characin with an unusual breeding habit. It lays its eggs in depressions in the gravel or on a flat stone. The male fans the eggs and looks after them. The breeding procedure is reminiscent of cichlids and sunfishes rather than characins about 200 to 300 eggs are laid, which hatch in 2 days. The female should be removed after spawning and the male soon after the fry become freeswimming. Recommended feeding system Aquaze tropical .
Popular name Spraying Characin. Origin Venezuela, Brazil, Guiana. Size 3 inches. Appearance An elegantly shaped slender fish with elongated fins.Feeding Accepts all foods. Water conditions Moderately soft neutral water. Sexing The male has longer fins and there is a white spot at the root of its dorsal fin. Breeding This fish is kept mainly because of its unusual breeding habit. It spawns outside water, e.g., on the surface of an overhanging leaf or on the undersurface of the aquarium cover glass. The conditoned pair are introduced in a 10- to 15-gallon, sparsely planted tank with the water level lying about 1″ to 1-1-1/2 inches below the cover glass. The pair swim side by side and together jump out of the water to the undersurface of the cover glass, where they adhere for a moment, deposit 10 to 15 eggs, and fall back into the tank. This act is repeated until some 100 eggs are laid. When spawning is completed the female should be removed. The male looks after the eggs and prevents them from drying by splashing them with water. This process sometimes dislodges the eggs or newly hatched fry which, when they fall into the water, are devoured by the male. If this is seen to happen, the male should be removed and an aerator stone fixed in the tank so that the spray from the bursting bubbles keeps the eggs damp. By about the fourth day the fry drop into the water and swim about freely. Just before this happens it is best to remove the male and rear the fry in the usual way.

Origin Upper Rio Negro. Size 1-1 -3/4 inches.Appearance This fish resembles the Neon Tetra (Hyphessobrycon innesi). It differs from it by being somewhat larger and more colorful, for whereas the red band in the Neon extends from the tail to the middle of the body, in the Cardinal it carries on to the gill covers. Behavior, Feeding, Water conditions, Sexing, Breeding Same as for Neon Tetra. Recommended feeding system Aquaze tropical .
Popular name Swordtail Characin. Origin Trinidad, Colombia, Venezuela. Size 2-2 1/2 inches. Appearance A cream-colored fish with rather long translucent fins. Behaviour, Feeding An undemanding peaceful species of interesting breeding behavior. Will take dried foods but needs a reasonable amount of live or fresh foods. Sexing The male has a peculiar, long, oarlike or spoonlike extrusion from the gill cover which extends halfway down the body. Its fins are longer and the lower lobe of the caudal is elongated. Hence the popular name Swordtail Characin. Breeding This is fairly easy but what happens during the mating act is as yet uncertain. The male approaches the female and extends his gill appendages so that they stand off at right angles to the body. The female sometimes turns around to snap at one of them. It is believed that at this stage the male somehow transfers a package of sperms (spermatophores) into the oviduct of the female. Once the female is fertilized in this fashion she will go on delivering fertile eggs for many months or even the rest of her life without further assistance from the male. This is a fairly easy fish to breed and is not . critical of water requirements. About 100 eggs are laid and the female looks after them and transfers them from leaf to leaf. The male should be removed after spawning; the female when the fry becomes free swimming.Recommended feeding system Aquaze tropical .
Popular name Blind Cave Tetra.Origin Subterranean streams and pools in Mexico. Size 2-2.5 inches.Appearance A silvery rose-tinted fish. Vestigial eyes and orbits vergrown with skin. These fish are derived from Astyanax fasciatus mexicanus which have normal eyes. It is believed that a long time agothese fish were carried by currents into subterranean streams and the eyes atrophied and became useless. Behavior Blindness does not present a serious handicap to this fish. It can be kept in a community tank with other fishes. A heightened sense of smell and vibration enables the fish to find its food and avoid bumping into other fishes.Water conditions Can be kept and bred in moderately soft or moderately hard, nearly neutral waters. Temperature 78°F. Sexing Shape is the only guide. Males are distinctly slimmer than females. Breeding This is easy with large mature specimens; 400 to 800 semiadhesive eggs are laid, which hatch in 36 hours. Fry have small eyes, which are probably functional. They can be reared in the usual manner, commencing with infusoria as first food. Recommended feeding system Aquaze tropical.
Popular name Lemon Tetra. At one time called Hemigrammus er ythrophthalmus, Origin Amazon. Size 1-1/4 inches.APPearance This fish is outstanding because of the pale lemon tinted body and the bright red color in the upper part of the eye. Behavior A peaceful community fish. Feeding Accepts all foods. Water conditions Moderately soft, slightly acid water. Temperature 80°F. Sexing Male slightly slimmer and more colorful. Breeding Not very easy. Peat water method should be employed. Recommended feeding system Aquaze tropical
Origin Peru, Brazil. Size 1-1/4 inches.Appearance Widely accepted as one of the most beautiful of aquarium fishes.

Behavior This is a rather hardy fish, well able to look after itself even in company of fishes twice its size. An ideal community fish which usually swims in the lower half of the tank. Feeding Takes all foods. Sexing The females are unmistakably larger and fatter than the male, the belly of which is flat or slightly sunken. Breeding This is considered to be a difficult feat.
