Relevant Information:

The genus Lithoxus have a circular mouth disc with a notched margin. Extremely strongly reduced dentition with only a small number of teeth. L. planquettei was first seen in the DATZ magazine of October 1989 as L044. Inhabits stony rivulets and has been collected in little forest tributaries (3 to 4 m wide) with shallow depth, rocky bottom, strong current, often with cascades. Likewise, during the dry season, it has been found in a split brook with very little water input, where only 2 species of Rivulus (R. igneus and R. cladophorus were present, thus suggesting that Lithoxus is a pioneer species which is capable of colonising difficult environments which are nutritionally poor. Aquarium Care: Quite a demanding genera which need pure, oxygen rich water. They need plenty of hiding places and the aquarium to be very strongly filtered. Diet: Insectivores that feed in their natural habitat from insect larvae on rocks. Feed Frozen mosquito larvae, brine shrimp and Daphnia. They will also except tablet foods.

Common Name:

L044, Planquette's rapids pleco.
