Scientific NameHypancistrus sp. (L316)   
Common NamesL316, Jari Zebra Pleco
Pronunciationhype an siss truss
EtymologyA contraction of the Greek hypo (meaning less than) and ancistrus, an allusion to the reduced number of teeth (particularly in the lower jaw) found in this genus.

Size 80mm or 3.1" SL. Find near, nearer or same sized spp.
IdentificationConfused with other similarly patterned species. Distinguishable from other similarly sized and coloured l-numbers by the smaller than normal eye and reduced set of teeth. Patterning on this fish is a poor identification characteristic as these fish are among the most variably patterned of all l-numbers. Young fish are very attractive rivalling the zebra pleco (H. zebra) for looks.

If you're new to l-numbers then it can look quite similar to a lot of them, but to the hard-core pleco watcher only really confused with L129 (Colombia) and L199 (Venezuela) the size of eye quickly distinguishes L316. L318 is also from the Rio Jari (the two have been jokingly titled ''BMW plecos'') may prove to be the same species as the only discernible difference is its lighter grey base colour. Oddly, it shares the exact same body sizes (including eyes) as L174, but is only similar visually at a young (<4cm) age.
SexingSexually mature at around 6cm, so you should be able to select pairs or a breeding group when purchasing. As males mature they become darker, less contrastingly patterned and grow odontodes (small hard spines) all over the body that never entirely go away but are much more prominent in breeding males.

Other ParametersLike many exotic plecos, will not suffer poor aquarium maintenance regimes, lacklustre filtration or aimless feeding.
Jump to next section Husbandry Information
FeedingNot picky, take a wide variety of live and frozen food such as bloodworms, brine shrimps, gammarus. Tablets, especially those with high percentage of Spirulina.
FurnitureRock caves or pipes should be provided one per male at least and driftwood is also appreciated but not mandatory. Plants are not molested but don't expect this guy to fix your algae problem.
CompatibilityA good community pleco, once settled (3-4 weeks) it will be seen during the day a bit more than many exotic plecos. Certainly not a territorial hell raiser, a pair or trio should be kept as reproduction isn't beyond the realms of possibility in a community tank.
Suggested TankmatesPeaceful but choose tankmates wisely as these fish do not compete well for food with particularly fast or aggressive tankmates.
BreedingReasonably easy to breed applying the usual small pleco cave spawning method, produces clutches of 10-25 eggs, the young require around 7-9 months to reach a saleable size.
