Common Name: Orange Seam Pleco
Scientific Name: Hemiancistrus guahiborum
Other Names: L106, L122, Red Fin Pleco
Description:
The Orange Seam Pleco is a striking freshwater fish known for its dark, almost black body contrasted with bright orange or red edging along its dorsal and caudal fins. This coloration makes it highly attractive to aquarists. The body is covered in bony plates, typical of plecos, and it has a sucker-like mouth adapted for grazing on surfaces.
Habitat and Distribution:
The Orange Seam Pleco is native to the Orinoco River Basin in Venezuela and Colombia. They inhabit fast-flowing rivers and streams with rocky substrates. These environments provide ample surfaces for grazing on algae and biofilm, and the strong current helps oxygenate the water.
Size and Lifespan:
In the wild and in captivity, Orange Seam Plecos can grow to about 5-7 inches (13-18 cm) in length. With proper care, their lifespan can range from 10 to 12 years, depending on the quality of the water and diet provided.
Diet and Behavior:
Orange Seam Plecos are primarily herbivorous, feeding on algae, biofilm, and plant matter in their natural habitat. In an aquarium, their diet should include high-quality sinking algae wafers, spirulina tablets, and fresh vegetables such as zucchini, cucumber, and spinach. They may also consume some protein-rich foods like bloodworms and brine shrimp occasionally. These plecos are nocturnal and most active during the night. They are generally peaceful and can be kept with other non-aggressive fish, making them suitable for community tanks.
Breeding and Reproduction:
Breeding Orange Seam Plecos in captivity is possible but can be challenging. They are cave spawners, with the female laying eggs in a secluded spot such as a small cave or hollow piece of driftwood. The male guards the eggs until they hatch. To encourage breeding, provide plenty of hiding spots and caves, and maintain optimal water conditions with regular water changes. Slightly raising the temperature and feeding a varied diet can help stimulate spawning.
Aquarium Care and Tank Requirements:
Orange Seam Plecos require a minimum tank size of 30 gallons. The tank should include plenty of hiding spots created with rocks, driftwood, and caves to mimic their natural habitat and reduce stress. Driftwood is especially important as it provides both shelter and a source of food. Efficient filtration and regular water changes are essential to maintain water quality. The water temperature should be kept between 75-82°F (24-28°C), with a pH of 6.5-7.5 and soft to moderately hard water.
Ideal Tank Mates:
Orange Seam Plecos are peaceful and can be kept with other small, non-aggressive fish. Suitable tank mates include tetras, rasboras, dwarf cichlids, and other small catfish. Avoid housing them with large, aggressive species that may cause stress or injury.
Difficulty Level:
Intermediate. While Orange Seam Plecos are hardy and adaptable, they require specific tank conditions and diet to thrive, making them suitable for aquarists with some experience.
