Adolfo’s Catfish Interesting Facts
- Adolfo’s catfish grows up to 2.2 inches (5.7 centimeters) in length and feeds on worms, crustaceans, insects, and plant matter.
- They are found in the Rio Negro basin of Brazil with a very low pH level ranging between 5.3 to 5.4 and a temperature around 78°F (26°C).
- Breeding this species is not easy as they lay eggs that attach themselves to plants or stones, and adults do not guard them. Optimal water chemistry for egg development may vary depending on their origin.
- The fry hatch at 26°C after four days. They begin feeding four days after birth, and raising them can be challenging.
Adolfo’s Catfish Habitat
Adolfo’s catfish are endemic to the Negro River basin in South America. They are usually found near the bottom of their environment.
These fish thrive in water that has a pH level between 6.0 to 8.0 and dH levels (water hardness) ranging from 2 to 25.
Their preferred temperature range is between 72°F to 79°F (22°C to 26°C), making them a tropical species.
| Water Temperature: | 72°F to 79°F (22°C to 26°C) |
| Water pH: | 6.0 to 8.0 pH |
| Water Hardness: | 2 to 25 dH |
Adolfo’s Catfish Physical Characteristics
Size: 2.2 inches (5.7 centimeters)
Adolfo’s catfish can grow up to 2.2 inches (5.7 centimeters) in length.
This is the standard length (SL) of male Adolfo’s catfish and those whose gender is not identified.
Adolfo’s Catfish Reproduction
Adolfo’s catfish lays eggs to reproduce. They breed in places like swamps, ponds, or streams in their natural habitat.
This species is hard to breed in an aquarium as they spawn in open water.
The female fish lays only a few eggs per spawning, and the eggs are not guarded by the parents.
To hatch the fry, you need to keep the water at a certain temperature and pH level. The process of raising the baby fish can be difficult too.
