BARYANCISTRUSDE DEMANTOIDES L200 «HiFin»
It took a while for the worldwide Pleco community to realize that there were two different species exported from Colombia as L200. The original one, Hemiancistrus subviridis, is more common in the trade. B.demantoides, often called L200 “hi-fin”, is rarer. B.demantoides is a very beautiful Pleco with it’s yellow/brown colours, and once settled it’s also a hardy aquarium inhabitant if given proper conditions. They will eat your Swordpants though.
Name: Baryancistrus demantoides (Werneke, Sabaj, Lujan & Armbruster, 2005)
Trade names: L200 “hi fin”
Origin: Rio Atabapo, Rio ventuari, Venezuela.
Maximum size: 17 cm / 7”
B.demantoides is very similar to Hemiancistrus subviridis (L200), which it lives syntopic with in the wild. They can be told apart by looking at the dorsal fin; in B.demantoides there is a membrane that connects the dorsal and adipose fin. If you look at their mouth, B.demantoides has a less circular mouth than H.subviridis.
L200 “hi fin” are true vegetarians, and should be fed a varied diet of vegetables and pellets containing much green matter. Some frozen foods and more meat-based dry food can be offered occasionally. B.demantoides does not grow as large as it’s Brazilian Baryancistrus cousins, but should still be offered a roomy tank. Clean, well filtered, oxygen rich, warm water is required. Breeding has occurred, but is rare. The male, recognized by it’s heavier odontodal growth and wider head, guards the clutch in a suitable cave.
