CATFISH
CORYDORADINAE SUB-FAMILY
The Corydoradinae sub-family consists of, among others, the genera Aspidoras, Brochis, and Corydoras.
Emerald Catfish, Short-bodied Catfish, Green Brochis, Emerald Brochis, Emerald Cory, Common Brochis
Brochis splendens
SYN: Brochis coeruleus, B. dipterus, Callichthys splendens
PD: The body is stocky and deep, with an arched back. Two rows of bony plates make up each side of the fish. The upper has 21-23 plates, while the lower 19-21. Two pairs of barbels are located on the upper jaw. The upper part of the lower plates are the same color as the upper plates, while the lower half is white. The upper row of plates have a metallic green to blue color, depending on the light. The fins are the tan to bronze in color. This fish is sometimes confused with C. aeneus but the differences are apparent when placed beside one another. B. splendens has a more pointed head, a greener color, and is deeper in body.
SIZE: To 4" (10 cm), although usually not larger than 2.8" (7 cm)
SS: Long-finned Brochis ( Brochis britskii ), Giant Brochis (Brochis multiradiatus ), Bronze Catfish ( Corydoras aeneus ), Golden-eared Cory ( Corydoras eques )
H: Along banks of slow-moving rivers with dense vegetation. South America; the Western Amazon Basin.
A: bottom
TANK: 20" (50 cm) or 10 gallons (38 L). Use fine gravel bottom, as this fish burrows. The tank should be dimly lit and well-planted. Provide hiding places with rocks, roots, and wood. Shallow tanks are preferred.
WATER: pH 5.8-7.8 (7.0), 2-30 dH (10), 72-82°F (22-28°C)
SB: A peaceful, undemanding fish, ideal for community tanks and beginning aquariasts. The Emerald catfish likes to shoal, so keep it in groups of 3 or more fish. Do not keep with substantially larger, aggressive fish such as large cichlids.
SB: Smaller tetras, Discus, Dwarf Cichlids, Livebearers, Gouramis, Barbs, Danios, Killifish
FOOD: Live; aquatic insects, white worms, Tubifex , Brine Shrimp, insect larvae; tablets; flake
SC: The females are larger, plumper, and less colorful
B: Spawning is initiated by the addition of cooler water. Recommended values for the water are: 72°F (22°C), pH of 6.0, and a dH of 2-4. The Emerald Catfish usually spawns in groups consisting of one female and several females. Each spawning produces 5-12 eggs and lasts between 1-3 hours. After all spawning is done, about 200 eggs remain on leaves, roots, stones and tank glass. Remove them and place in a rearing tank. The fry hatch in 5-6 days, at which time they swim immediately to the bottom. Feed microorganisms and small tablets. The fry are green in color on the front half of their bodies while the rear part red.
BP: 8. Breeding the Emerald Catfish is difficult.
R: The Emerald Catfish is hardy, but good water conditions are needed if its metallic green or blue color is to develop. Species of the genus Brochis can be distinguished from Corydoras species by their presence of more dorsal rays.
DC: 2. A hardy catfish recommended for almost any community tank.
Genus Corydoras
SIZE: From 1" (2.5 cm) to 4" (10 cm)
H: This family is spread throughout South America with the greatest concentration found in the Amazon Basin. Corydoras catfish come from a wide range of biotopes; from rocky rapids to slow-moving, muddy rivers.
A: Most swim in the bottom levels of the tank. Some dwarf species may swim in mid water.
TANK: Most can tolerate an aquarium that is 20" long (50 cm) or has the capacity of 10 gallons (38 L). These catfish like a well-planted tank with many hiding places (wood, roots, rocks). Use fine gravel or sand as a substrate, for these fish burrow. Members of the Genus Corydoras prefer shallow tanks.
WATER: With most individuals of this species, water properties are not critical. Most thrive in water with a pH of 6-8, a hardness of 2-25 dH, and a temperature of 72-82°F (22-28°C).
SB: All of the fish in this family are good community fish. They like to school and should be kept in groups. Do not combine Corydoras species with huge fish as they may eat this pleasant little catfish. Corydoras catfish are diurnal fish.
SB: Smaller tetras, Discus, Dwarf Cichlids, Livebearers, Gouramis, Barbs, Danios, Killifish
FOOD: Live; aquatic insects, white worms, Tubifex, Brine Shrimp, insect larvae; tablets; flake
SC: It is fairly difficult to distinguish between the sexes, although the mature females are usually plumper.
B: Use a breeding tank with a sand or fine gravel substrate. Provide some large-leafed, potted plants. Usually spawning occurs after addition of cooler water, in water with a pH of 6-7 and a water hardness of about 6 dH. The most success of spawning Corydoras catfish is reported during the winter months that correspond to the rainy season of their natural habitat. Recreating rainy season conditions this far has lead to the most spawning successes. For Corydoras catfish, just the change ion temperature is usually enough to initiate spawning. One-fourth of the tank's water should be changed daily, with cooler water added after each change. Continue this until the temperature has been lowered 4-8 F. Corydoras catfish usually spawn in groups. The female holds 2-4 eggs between her ventral fins while the male fertilizes them. After being fertilized, the eggs are carried by the female to a large leafed plant, where they are attached to the underside of a leaf. In all 100-400 eggs are laid. The eggs should be removed as the parents may consume them. Place the eggs in a well-aerated rearing tank after spawning is complete. The eggs are somewhat sensitive to fungus, so the tank should be kept as dark as possible. Fry hatch after 3 days and are free-swimming in 3-5 days further. Young should be fed small live foods such as white worms, Tubifex , Brine Shrimp nauplii, innards of fresh peas, and water fleas. The fry can also be fed tablet foods. Young grow quickly.
BP: 7. Breeding is fairly difficult.
R: This family has the ability to take atmospheric oxygen from the surface which aides them in water with insufficient amounts of oxygen. Air is taken in through the mouth and passes along the intestine to the hind gut, where it absorbed into the blood stream.
DC: 2. As a general rule, Corydoras catfish are easy to care for.
