Panaqolus maccus
The clown pleco is a small Panaqolus species with bold orange-brown and black banding. It is a specialised wood grazer: digestion relies on soft driftwood and aufwuchs, not just algae. Native to rocky, fast-flowing tributaries in the Orinoco system. Peaceful with most community fish but needs stable warm water, excellent oxygenation, and multiple wood pieces; territorial with similar plecos over favourite hides.
Soft driftwood; sinking algae or wood-based wafers; occasional blanched veg. Low protein.
Frequency: Daily
Wood is not optional—fish need to rasp fibre; replace soft wood as it breaks down.
Native Region: Venezuela (Rio Orinoco tributaries)
Rocky riffles and wood tangles with strong flow and high oxygen.
Strong gentle circulation; smooth rock caves; no sharp gravel; footprint over height.
Activity Level: Low
Nocturnal browser; clamps to wood and rock by day. Can be shy until established.
Difficulty: Difficult
Type: Cave spawner
Sexual Dimorphism: Females often fuller-bodied; males may have more odontodes on pectorals when mature.
Cooler clean-water changes sometimes reported to trigger spawning; cave with smooth entrance.
Substrate: Sand
Plant Safe: Yes
Several driftwood branches; dim lighting encourages daytime activity.
