One of the most attractive Ancistrus species is this so far not scientifically identified species from the middle Rio Negro in Brazil. There the beautiful fish is not rare, in some places even very common, but the species apparently prefers biotopes which are avoided by the local fishermen; otherwise it can hardly be explained why L184 is imported only so comparatively rarely. In the meantime, however, offspring are more frequently available, including the fish we can currently offer in small numbers.
While L184 has been found in nature in stately specimens of 15-18 cm length, the offspring always stay smaller, breeding already with 6-8 cm length and usually stop growing with 10-12 cm length. The reason for this is unknown, almost all other fish species usually grow larger in the aquarium than their wild cousins.
Apart from a high level of attention required by these Ancistrus for breeding and during rearing – very soft water with a pH around 5 and extremely low bacterial water loads – L184 are not particularly demanding when maintained “normally” without breeding intentions and are well suited for maintenance in community aquariums. However, one should not keep other, possibly even aggressive loricariids together with L184, because the “Brilliant Ancistrus”, as L184/L107 is popularly also called, is a very defensive species, which can be easily suppressed.
L184 differs from all other similarly marked Ancistrus species by the combination of the following characteristics: very flat body, broad head, white spots in the dorsal fin, no white fringe in dorsal or tail fin, pointed tail fin ends (white in juveniles).
