Green Phantom Pleco (Hemiancistrus subviridis)

This striking pleco is native to Venezuela, found only in the fast-flowing, highly oxygenated waters around the junction of the Ventuari and Orinoco rivers, where it lives among rocks and boulders in strong current.

It has a light olive-green body covered in yellow to cream spots, most concentrated towards the head, giving it a distinctive appearance compared to the more commonly seen brown plecos.

Juveniles are relatively peaceful, but as they mature — particularly the males — they become increasingly territorial towards other plecos and similar bottom dwellers, so tank mates should be chosen with this in mind.

Because they come from fast, well-oxygenated rivers, we recommend strong water flow and excellent oxygenation in the aquarium, along with pristine water quality — this species is sensitive to poor water conditions and organic waste build-up.

Care

• Fish size: up to 15cm

• Tank size: 210 litres (55 US gallons) minimum

• Temperature: 24-28℃

• pH: 6.0-7.5

• Filtration: strong filtration with good water movement and oxygenation

• Diet: omnivore — algae wafers, sinking pellets, bloodworm, brine shrimp, with some blanched vegetables

Sexual Differences: Males develop a broader, flatter head and longer pectoral fin spines as they mature, while females remain narrower-headed.
