Overview
The pearl-spotted angel pleco is a genuinely small Hypancistrus for a calm community tank. It suits a keeper with some experience.
Did you know
The pearl-spotted angel pleco's species name, margaritatus, is Latin for adorned with pearls. For so small a fish, it wears the dense pale spotting of a fish several times its size. That spotting is why collectors prize it.
Caring for the pearl-spotted angel pleco
Give the pearl-spotted angel pleco at least 42 gal (160 L), which is ample for a pair with caves. Build a scape of stacked stone and driftwood full of tight caves, set over sand. It lives on the bottom among the rock and wood and wants its own cave to claim.
Keep the water soft and warm, at 79 to 86°F (26 to 30°C) with a pH of 5.5 to 7.2. Give it gentle current and clean, well-filtered conditions. A little tannin from leaf litter suits its blackwater origin.
It shares the carnivorous bent of its genus, so feed meaty sinking foods rather than relying on algae. Offer frozen bloodworm, baby brine shrimp and good carnivore pellets.
Keep a single fish or a compatible breeding pair rather than a group, since adults defend cave space. It is peaceful toward other fish and pairs well with small, gentle community species.
Breeding is of moderate difficulty and follows the usual Hypancistrus way. The male guards the eggs in a cave until the young emerge.
Good to know
Hypancistrus margaritatus is a dwarf member of the family Loricariidae, dark charcoal sprinkled with close-set pale spots. Milton Tan and Jonathan Armbruster described it in 2016.
In the wild
The pearl-spotted angel pleco was found in the Takutu drainage on the border of Guyana and Brazil. It lives in warm, rocky creeks of the Rupununi lowlands.
