Sales Description

The Super Red Calico Bristlenose Pleco is an eye-catching color morph of the beloved Ancistrus species, showcasing a vibrant mix of deep reds, oranges, and marbled calico speckling across its body and fins. Their striking coloration makes them a standout addition to planted aquariums, community setups, and specialty pleco tanks. Hardy, peaceful, and beginner friendly, these plecos maintain the classic bristlenose traits while offering a rare and highly sought-after color combination.

This variant is smaller and more manageable than many pleco species, making it ideal for home aquariums. Along with their unique coloration, males develop distinctive bristles along the snout as they mature, adding to their charm. They are excellent grazers that help control soft algae, making them both beautiful and functional.

Care Guide

Super Red Calico Bristlenose Plecos thrive in aquariums of 20 gallons or larger. Provide natural hiding spots such as caves, driftwood, and shaded areas, which help them feel secure and encourage natural behaviors. Driftwood is especially recommended, as Ancistrus benefit from grazing and rasping on it for digestive health.

Ideal water parameters include a temperature range of 72–82°F (22–28°C), pH between 6.4 and 7.6, and reasonably stable, clean water with moderate flow. Regular water changes support good health and help the fish maintain their vivid coloration.

Their diet should include a mixture of high-quality sinking wafers, spirulina pellets, algae-based foods, and fresh vegetables such as zucchini, cucumber, and blanched spinach. Although they graze on algae naturally, they cannot survive on algae alone and require proper feeding. Occasional protein foods such as frozen bloodworms or repashy gel diets are beneficial in moderation.

Compatibility

The Super Red Calico Bristlenose is peaceful and compatible with community fish, livebearers, tetras, rasboras, rainbowfish, dwarf cichlids, and more. They coexist well with other bottom-dwellers as long as there is enough space and hiding areas. Avoid housing them with large aggressive fish that may harass or outcompete them.

Breeding Notes

These plecos are one of the easiest pleco species to breed. Males guard a cave or enclosed structure where the female deposits eggs. After the eggs hatch, the fry remain in the cave until they become free-swimming. Providing a stable environment, appropriate caves, and a vegetable-rich diet greatly increases breeding success.
