THE LIFE CYCLE OF FISH IN POOLS

Posted in Fish Feeding Systems

In nature these fishes often occur in small pools or drainage ditches, which in some instances dry up during the summer. Survival of the species in such instances is assured by eggs lying dormant in the Life cycle of an Annual fish in nature. (l) The parent fish spawn. laying their eggs beneath the mud. (2) The egg as it lies partially in the mud, partially out. In time. the egg will work itself entirely beneath the mud. (3) As he dry season arrives the water hole dries, leaving only dried mud, the eggs safely buried within. (4) With the advent of the rainy season, the pool is again flooded and the fry hatch. (5) As the pool fills with wilter,aquatic organisms and insects nourish the fry and it starts to grow, ultimately to repeat the cycle all over again.

African Tooth-Carps

Posted in Fish Feeding Systems

This genus contains many brilliantly colored fishes, which unfortunately fare rather poorly in community tanks.Under such circumstances they go about with folded fins, hide in corners, and rarely last very long. To appreciate the breath-taking beauty of these fishes it is best to give each species a separate tank. Further, in many of the larger species the males are so aggressive toward each other that it is best to keep only one male with three or four females. The tank should be placed in a shaded position and surface-floating plants provided. The bottom is best covered with well-washed scalded peat prepared as described earlier.Recommened Feeding System Aquaze Tropical.

Geisha Girl Medaka, Japanese Medaka, or Ricefish.

Posted in Tropical Fish

Oryzias latipes Schlegel 1850 Origin Japan. Size l.5 inches.Appearance A rather prosaic grayish-green fish kept mainly for its interesting breeding habit. Strains with a golden and reddish body color have also been developed. Behavior A delicate fish unlikely to fare well in a community tank with more boisterous companions. Best kept with its own kind.Feeding Accepts all foods.Water conditions Moderately soft, slightly acid water to which approximately 1 level teaspoonful of salt per 3 gallons of water is added. Temperature range 75°F.-80°F. Does best at 78°F.Sexing Females are plumper and have shorter, rounder fins, Breeding Set up as described above, genera Aplocheilus and Oryzias. Can be spawned in pairs or in small groups. Since parents molest neither eggs nor fry, breeding is a simple matter of feeding parents adequately and collecting fry as they hatch out for rearing in separate tanks. Breeding behavior particularly interesting.After the male and female have come together the fertilized eggs are carried on the ventral surface of the female,attached by a fine mucoid thread for many hours before they are brushed off on plants.Eggs hatch in 10/14 days.Recommended feeding system Aquaze Tropical.

Asiatic Tooth-carps

Posted in Tropical Fish

The Asiatic Tooth-carps are mainly surface-living fishes that are found in fast-moving streams, ponds, and small drainage ditches.Little wonder then that they are not very demanding in their water conditions or temperature requirements. They do well in a temperature range between 70°F. and 80°F., in all except very hard alkaline water. In their native habitat they live on mosquito larvae and other insect life. In the aquarium too it is advisable to give them a fair amount of live and fresh meaty food, and only occasionally dried foods. Recommened feedlng system Aquaze tropica.

Tooth-carps

Posted in Tropical Fish

This large family of fishes is widely distributed in the tropical and subtropical region of every continent except Australia. The distinction between these fishes and the true Carps is clearly indicated by both the scientific and the popular name of this family. Carps have pharyngeal teeth but a toothless mouth. The Cyprinodontidae have both oral and pharyngeal teeth. These fishes usually have a flattened head with an upturned mouth. No barbels or adipose fins occur. Some of the Cyprinodontidae are egglayers, others livebearers. In the latter the anal fin is modified to form an intromittent organ called the gonopodium. So varied are the aquatic needs and methods of reproduction in this family that broad generalizations are inadequate.It is essential to consider each genus, and at times each specics, separately. It should be noted that the distinction between the egg-laying and livebearing species is one of convenience. Taxonomically some of the livebearers are more closely allied to some egglaying forms than to other livebearers. Recommened feeding system Aquaze Tropical.

Midget Sucker Catfish.

Posted in Catfish, Tropical Fish

Otocinclus affinis Popular name Midget Sucker Catfish. Origin Southeast Brazil. Size 2 inches. Appearance A gray-green to brown fish of not very attractive appearance. Behavior This is the supreme algae eater for the usual community tank, which will not damage even the finest-leaved plant. One or more should be used, depending on the size of the tank. A long lived hardy species if right conditions are provided. Feeding Unless algae are available this fish will not survive long. Also accepts the other usual foods including dried foods. Water conditions Not critical. Wide temperature range, does well at 78°F. and also at 65°F. for considerable periods. I have kept them in tanks housing fancy Goldfish. Sexing Adult female markedly fatter than male. Breeding This is similar to the Corydoras. Eggs are laid on the glass and on plant leaves. Young hatch in 2 or 3 days and cling to glass or plants for a similar period before they drop to the bottom searching for food. Fry reared on mashed worms, algae, and dried foods. Recommended feedlng system Aquaze tropical.

It is a brownish fish with mottled black markings, which blend with the aquarium gravel. Behavior A peaceful community fish which would no doubt be more popular if it were freely available.Recommended feeding system Aquaze Tropical.

LORICARIIDAE

Posted in Catfish, Tropical Fish

The Loricariidae, like the Callichthyidae, are armored Catfishes from Northern and Central America. They have three or four series of bony plates on their sides, in contrast to the Callichthyidae which have only two. The head and the dorsal (back) and ventral (under)surfaces (except the abdomen) are also protected by bony plates in most species. The first ray of all fins except the caudal is stiffened to form a spine.Recommended feeding system Aquaze Tropical.
