L236 Glaser (yellow line)

Name: Hypancistrus sp. “L236 Glaser”

Trade names: 

Origin: Rio Xingu, Brazil.

Maximum size: 12 cm / 5''

The “L236 Glaser” in our care never grow bigger than about 12 cm. This could be due to various reasons of course, but it could possibly suggest that L66 and L333 were not part of the original breeding stock that supplied Glaser. L399/400 seems more likely, as this form is already very variable in the Xingu river. Our line varies in base colour from white to cream-yellow, and always show broad, black wormlines – usually with little space in between. This pattern certainly fits with the original L236, but it can also be found in other Xingu forms like for instance L333. It's more than likely that the original L236 was either a young L66 or an L399/400.

They need an aquarium set up consisting of lots of hiding places in the form of rocks, wood and of course specially made caves that suit their measurements. In these the males will eventually guard their offspring. They prefer water that is fairly warm (27-30 C), soft and slightly acidic. Most of all it should be well oxygenated and clean, so a good filtration system and frequent water changes are essential. Among themselves they are fairly peaceful, although males may quarrel for caves and females can sometimes be badly injured or even killed during the breeding-trapping in the male's cave. Males develop longer odontodes on their pectoral fins and on their cheeks, and have broader heads. Hypancistrus are mostly carnivorous, so a selection of crustaceans, insect larvae and fish meat should be offered along with high quality dried foods that also contain some vegetable matter.
