Max Size - 100mm or 3.9" SL. Find near, nearer or same sized spp.
Identification - Mature males and sometimes females have soft tentacles (bushy fleshy growths) on the snout - this is unique to the genus Ancistrus.
Sexing - Males develop soft tentacles on the head and while sometimes females also do, it is never to the grand extent of those found on that of the conspecific male.
General Remarks - L144 is a one off import - the one male fish that came from Paraguay was at the time bred together with females imported at the same time, and then crossed back to their own siblings to lock the genetic defect that causes the yellow colour. These fish died out in the late 1990s as far as anyone can tell. The fish that is now sold as L144 is a different form, most likely based on Ancistrus cf. cirrhosus. This form resembling L144 can be found under as Ancistrus sp. (4).
