Crenicara filamentosa, Ladiges, 1958
Origin: Brazil, Rio Negro and Rio Orinoco tributaries.
Etymology:
filamentosa refers to the filaments
on the caudal tail.
Synonyms: None
First import:unk
Description: See picture, a juvenile Crenicara filamentosa is visible. Full grown animals have two horizontal stripes, one iridescent blue stripe above the spots on the side, and an iridescent greeen line below those spots. Fins transparent with tiny blue and red spots. Caudal fin with two filaments.
Care: Not suitable for the average community tank. Soft, slightly acidic water is required, filtration over peat is advisable. Tempered light, a dark soil, lots of hiding places created with driftwood and plants. The more hideouts are available, the more frequently the fish will show themselves. Frequent small waterchanges are necessary, as well as a varied diet.
Temperature: 22-26 degrees.
Feeding: Only small live food is accepted by wild caught fish, aquariumbred fish will also accept small frozen food.
Size: Males including the tail up to 9 cm, females 6 cm.
pH: 5.0-6.75.
Breeding: Tank should be similar as the one described in the care section, water should be extremely soft and acidic. The fish will spawn in holes, but also on stones and plants. A sandy soil is required, in which the mother will create ditches to place the fry in after they hatched. Up to 120 eggs are laid, which will hatch in approximately 2 days. The females will protect the eggs ferociously against all fish, including the male. It's best to remove the male after spawning. When breeding, the females pelvic fins turn bright red, which serves as a beacon to the fry, who will respond to it. The eggs easily develop fungus if the waterconditions are inadequate.
Sexual dimorphism: Females have rounded transparent fins, males larger.
Prices:Netherlands: 4-5€
