Size 80mm or 3.1" SL. Find near, nearer or same sized spp.
IdentificationNot easy as many different Hypancistrus from various rivers have about the same range of size and colour pattern. L136a and b are the same as LDA05 and LDA06 and are all the same variable species. L136c is a rarely found variant that is probably the same species but this is less certain. L158 is an adult L136c/LDA06. Belly white on both sexes.
SexingTypical for the genus.
Male: interopercular and pectoral odontodes longer. Plate odontodes on the body. Hard ray of pectoral fins broader. head wider and longer.
Female: smaller size and rounder in the ventral.

Jump to next section Husbandry Information
FeedingMostly carnivorous, live or frozen food or the commercially prepared types such as tablets and pellets. Eats a bit of vegetables but should not be the main diet Is not an algae eater. Does not chew wood.
FurnitureSand, driftwood, caves made of slate, clay, bamboo, PVC tube.
CompatibilityTerritorial towards conspecific and other Loricariids that have the same size range. Rather shy
Suggested TankmatesSmall tetras and other similar small fish. Also Corydoras. Care has to be taken to ensure that they get enough food, as they can be a bit shy and slow to grab food when available.
BreedingGood water change with drop of temperature every 2 days with heater left unplugged overnight right after the water change can trigger spawning. Female lays around 30 eggs in a cave being guarded by the males until the yolk sac is absorbed.

Lovely shy L136 If you are interested and have other hypans for exchange or want to get some young ones off from me do let me know. Deal only if you're in Singapore, or if you know the export procedure in Singapore and your country cause I'm unsure.", (23) Sanplec (k: 12), (24) leej24, (25) nessaja, (26) balken89, (27) Eivind (k: 3), (28) Id16, (29) Wijnbelevenis, (30) steph en jess (k: 6), (31) frog72 (k: 9), (32) parrot1974 (k: 2), (33) Kanta, (34) JSamuels, (35) LostYeti (k: 4), (36) Andrewjw (p: 2), (37) kwalker, (38) Nuwar, (39) awesome wels, (40) CharlieM9, (41) FishJunky, (42) Junglejason, (43) Alta, (44) Steven Jansen 72 (k: 4), (45) amazonaquatics, (46) Colinlock, (47) Allanski, (48) Redrain, (49) Calcium, (50) Heriberto.gj, (51) Vierrollenfreak, (52) ed1402, (53) xroadiexstevex, (54) Armand (k: 4).
