Rineloricaria fallax, Steindachner, 1915
Origin: Paraguay, La Plata region. Here the fish occur in fast flowing shallow rivers.
Synonyms: Loricaria parva, Loricaria fallax
First European import: Germany, 1908, Vereinigte Zierfishzüchtereien
Description: See pictures
Care: The fish are best kept in tanks that are well filtered and with temperatures in the lower regions, since they require lots of oxygen. Other than that they can be kept in almost any kind of water. A 60 cm tank should be considered the minimum, some hideouts should be available and preferably a sandy soil although that is no requirement.
Temperature: 15-25 degrees
Feeding: Flake food, spirulina, algae
Size: Up to 18 cm
pH: 5.8 - 7.8; dH range: 20.0
Breeding:Besides proper conditions and well fed animals, a suitable breeding place should be offered. PVC pipes of 3 or 4.5 cm diameter, longer than the fish, can be used for this purpose. Breeding the fish is best done in the community tank. After the female lays the up to 200 1mm eggs, the male will fertilize them and guard them until they hatch(9-12 days). After 7 days, remove the tube from the community tank, during this proces the male will (usually)stay in the tube, and place it in a breeding tank with the same water. It's best to keep the male with the eggs, since he will aid the fry when the try to break through the eggshell. The fry are extremely sensitive to infusoria and deteriorating waterquality. Keep the tank very very clean, and feed lots of small live food and later on algae.
Sexual dimorphism:Males have bristles on the snout.
Additional: An albino variety has been bred, see the picture on the left.
