Hemiancistrus sp. L128
Blue Phantom Pleco (L128)
紫钻琵琶
May be the same species as L200 Hemiancistrus subviridis in which case L128 is the northern form. An inky black fish with variable blueish white spots. 
This stunning species must surely rank among the most attractive Loricariids available in the hobby. There are several colour forms available, depending on collection locality. These vary in base colour and in the number, size and positioning of the spots on the body. 

The true identity of this fish is shrouded in confusion. It may or may not be Hemiancistrus subviridis, also known as the green phantom plec (L200), which it resembles very closely in morphology. The two are also found in different parts of the same river system. Compellingly, the darker forms of L128 are found at the northenmost end of this range, with the fish becoming progressively lighter in colour as the river travels south. At the end of its range, L128 gives way to the darkest form of H. subviridis, which also becomes lighter as the river moves yet further south. This would certainly appear to suggest that the two fish are colour forms of the same species, but as things stand we are still awaiting scientific confirmation of the true identity of L128. Even placement in the genus Hemiancistrus should only be considered tentative.
