Hemiancistrus subviridis
A medium-sized pleco with fine yellow spots over a yellow-green body. It lives among granite boulders in the upper Orinoco and feeds on insects, algae and mosses. Note that it shares the number L-200 with another species.
Hemiancistrus subviridis is a loricariid catfish of eastern Colombia and western Venezuela, occurring in the upper Orinoco above the Atures rapids and in the Iguapo, Ventuari and Casiquiare rivers. It lives in the spaces between granite boulders and feeds on insects, algae, bryophytes and other plant matter. FishBase records 15cm standard length. Fine yellow spots over a yellow-green body give it the name green phantom pleco. In the hobby the number L-200 is applied to two species, this one and Baryancistrus demantoides, and their close resemblance has historically led them to be treated as the same or as close relatives. The IUCN assesses it as Least Concern and it is not listed by CITES.

Algae, bryophytes, aquatic insects and sinking dried foods
It reaches 15cm standard length. In the wild it hides in crevices between granite boulders, so build plenty of gap-like refuges from stacked rocks and make sure they are stable.
It inhabits running water above the rapids in the upper Orinoco, so keep the water clean, moving and well oxygenated.
It is a benthic fish that occupies rock crevices, so provide more refuges than there are fish.
Wild fish eat insects, algae, bryophytes and other plant matter. Base the diet on sinking dried foods containing both animal and vegetable matter and supplement with frozen bloodworm and vegetables.
Captive breeding records are scarce. As a crevice-dweller it first needs plenty of stable rock refuges in which to settle.
It shares the number L-200 with Baryancistrus demantoides, so traded fish cannot always be assigned to one species; body shape and fin form are the useful characters. The IUCN assesses it as Least Concern and it is not listed by CITES.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
