Identity and locality
Baryancistrus demantoides
Upper Orinoco drainage, Venezuela
Diagnostic evidence and naming
Formally described in 2005. Dorsal-fin membrane extends to join adipose fin, distinguishing it from Hemiancistrus subviridis. Both have appeared under the L200 trade code, but are different species. The 2005 type description distinguishes a dorsal-to-adipose fin membrane connection; this is not the same species as H. subviridis even though both use L200 in trade.
Breeding and genetics limitations
Species-specific care and documented captive-breeding records needed. Do not group all L200 stock as one species.
