coeruleus, B. dipterus, Callichthys splendens
Physical description: 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/Length: To 4" (10 cm), although usually not larger than 2.8" (7 cm) Similar species: Long-finned Brochis (
Brochis britskii ), Giant Brochis

), Golden-eared Cory (
Corydoras eques )
H: Along banks of slow-moving rivers with dense vegetation. South America;
the Western Amazon Basin. A: bottom Aquarium: 20" (50 cm) or 10 gallons (38 L).
Use fine gravel bottom, as this
The tank should be dimly lit and well-planted.
Provide hiding places with rocks,
roots, and wood.
Shallow tanks are preferred. Water chemistry: pH 5.8-7.8 (7.0), 2-30 dH (10), 72-82°F (22-28°C) Social behavior: A peaceful, undemanding fish, ideal for community tanks and beginning
The Emerald catfish likes to shoal, so keep it in groups of 3 or more
Do not keep with substantially larger, aggressive fish such as large
cichlids. Social behavior: Smaller tetras, Discus, Dwarf Cichlids, Livebearers, Gouramis, Barbs,
Danios, Killifish FOOD: Live; aquatic insects, white worms,
Tubifex , Brine Shrimp, insect larvae;
tablets; flake Suggested companions: The females are larger, plumper, and less colorful Breeding techniques: 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. Breeding potential: 8.
Breeding the Emerald Catfish
is difficult. Remarks:
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
can be distinguished from
Corydoras species by their presence
of more dorsal rays. Difficulty of care: 2.
A hardy catfish recommended
for almost any community tank.
