|Cat-eLog Data Sheet|
|Scientific Name||Hemiancistrus subviridis Werneke, Sabaj, Lujan & Armbruster, 2005|
|Common Names||L200, Green Phantom Pleco
Gold-Yellow-Ancistrinae (Germany), Green Pleco, Grøn Fantomsugemalle (Denmark), Lemon Spotted Green Pleco
|Type Locality||Rìo Orinoco 117 km W of La Esmeralda, 03.28998°, -066.60004° Amazonas, Venezuela.|
|Etymology||Greek, hemi = the half. While the Greek, agkistron = hook, is thought to be the root of the term ancistrus, hemiancistrus can be taken to mean that these species have a part (not exactly HALF) of the features of the genus Ancistrus, but not ALL of the features. This specific epithet refers to its olive green colour in life.|
- CotM 2003 September
|Size||190mm or 7.5" SL. Find near, nearer or same sized spp.|
|Identification||The green colour form of this fish can only really be confused with Baryancistrus demantoides. The key to tell these two apart is that the dorsal fin and the adipose fin are connected in Baryancistrus species, and separated in the this species. Furthermore, have a look at the shape of the mouth. H. subviridis has a almost perfectly round mouth, while B. demantoides shows a more rectangular mouth.
Ranges in colouration from blueish green to yellowish green (which correlates to how far south on the Rio Orinoco the fish was collected). Head and body spots are variable within these colour forms. May be the same species as L128.
|Distribution||South America: Venezuela: Upper Rio Orinoco from at least at Minicia up to Rio Ventuari and in the Rio Ventuari itself.

|pH||6.0 - 7.8|
|Temperature||22.0-25.0°C or 71.6-77°F (Show species within this range)|
|Other Parameters||This fish revels in fast flowing water.|
|Feeding||The fish is omnivorous and easy to feed. Although an effective algae eater, it should be given a varied diet of prepared foods.|
|Furniture||Lots of vertical stonework and rounded boulders. Bogwood and plants are not necessary. Water current should be at its strongest over cracks and crevices in the rocks where the fish will live.|
|Compatibility||The challenge with this fish is to find fish that will live in such fast water. It will live in calmer water should you wish to keep this fish in a medium sized community setup. A good "starter" l-number.|
|Suggested Tankmates||This fish is a good pleco for a community tank despite its natural habitat in rapids as it will adapt to less hectic water conditions. If you do want to try faster water, Semaprochilodus characins and silver dollars of various types are a good choice for mid-water companions.|
|Breeding||Has been bred in the aquarium. A cave spawner, the male guards a clutch of approximately 40 eggs. Eggs hatch in 3-4 days, fry absorb their yolk sac and start feeding in 10-11 days.|
|Breeding Reports||There are 5 breeding reports, read them all here.|
|References||DATZ matches Aqualog which features this fish in supplements 1 and 2.
