CATFISH




MOCHOCIDAE FAMILY
The Mochocidae or Naked Catfish Family includes some ten genera, including the well-known genus Synodontis, and 110 to 170 species. Mochocids are found throughout the lakes and rivers of Africa. This family is sometimes known as The Upside-down catfish family because of some fishes' tendency to swim or hover belly up.
SIZE : The Mochocidae Family includes medium to large fish, usually not more than 12" (30 cm).
S : The fish of this family usually swim in the lower levels.
TANK : The tank ranges in size depending on the size of the fish. For most, it should be at least 28" (70 cm) long or 20 gallons (75 L). The African river Mochocidae like a well-planted tank with floating plants and plenty of hiding places. Lake Mochocidae should be kept in a tank with rocky areas and caves for hiding. The substrate for both groups should be soft.
WATER : The catfish from the various rivers of Africa can tolerate a pH from 6-7.5. They like soft to medium water ranging from 4-15 dH, and require a temperature of 72-82�F (22-28�C). The Mochocidae catfish from the Great African lakes prefer more alkaline, harder water. Most can tolerate a pH ranging from 7.0-8.5 and a water hardness of 10-30 dH.
SB : Most of the species in the Mochocidae Family are peaceful and nocturnal. Although their evening behavior often prevents other fish from sleeping, these fish are recommended for most community tanks. These fish can be combined in a community tank with nearly all other fish. Some of the larger species may eat smaller fish.
SC : Most Synodontis species can be kept with medium to large sized fish. Most species can be combined with African Rift cichlids, or West African cichlids andAfrican tetras.
FOOD : Live, dry, and frozen foods that reach the bottom. These fish should be fed in the evening.
B : Few fish in this family have been bred. Some species that have successfully bred, although it is usually difficult. For almost all species, the rainy season plays an important role in triggering spawning. There appears to be three main spawning method S : species that lay eggs that adhere to vegetation, species that scatter their eggs, and species that practice the "Cuckoo" method of S. multipunctatus. Most species must be two or three years old before sexual maturity is reached.
BP : Difficult.
R : The fish in this family have three pair of barbels and in most cases, are scaleless, except for the head. These fish should be netted carefully, because most have small spines. Many species have the ability to emit squeaking noises when alarmed and appropriately are referred to as Squeakers in southern Africa. A few species have the ability to discharge small electrical signals. Most species possess spines capable of inflicting wounds.
DC : Most fish of this family are hardy, but there are some exceptions.

S. polli differs from S. petricola in having a darker body pattern. S. dhonti attains a larger size and loses its body spots with age.
HAB : Eastern Africa; rocky shores of Lake Tanganyika, at depths up to 65 feet. This fish is exported from the Burundi district.
S : bottom
TANK : A 30" (76 cm) or 20-30 gallon (76-114 l) tank is sufficient for fish to 4" (10 cm). Larger fish require a tank measuring at least 40" (102 cm) or45-55 gallons (170-209 L). The tank should have a rocky set-up with caves and plenty of other hiding places. Use fine gravel or sandy bottom.
WATER : The water should be clean and nitrate free with a pH of 7-8.5 (8.1), a water harness of 10-35 dH (16), and a water temperature of 75-82�F(24-28�C).
SB : A good community catfish. The cuckoo catfish can be kept in groups of 2-6 fish while they are young. Adults become solitary and should be kept singly, or in groups of three or more.

B : The Cuckoo Catfish waits for a pair of cichlid mouth-brooders to spawn. The catfish drops her small eggs (measuring 1.5 to 2 mm in diameter) among the cichlid's eggs. The female cichlid picks them up, thinking they are her own eggs, and cares for them in her mouth. When the young catfish hatch, in the cichlid's mouth, they feed on the young cichlid's yolk sacs until the catfish can fend for themselves. Start feeding with Artemia nauplii.

B : The eggs (up to 450) are deposited in a depression made in the bottom. Parents look after the brood. The yolk sac disappears after 4 days. After 7 to 8 weeks, the fry change from spending all their time swimming like normal fish, to the standard swimming position of the Upside-down Catfish of about 50%upside-down, 50% right-side up. Will forms schools while young.
BP : 8. A difficult fish to breed.
R : This fish swims upside-down so it can see predators that approach. The Upside-down Catfish also swims in this manner for feeding on the underside of leaves and fish. Lockable spines make it difficult to remove from a net. Often this species will hide during the day.
