Eigenmannia virescens
SYN :
Cryptopshumboldtii, C. lienatus, C. virescens,Eigenmannia lineata, E. humboldtii, Sternarchus virescens, Sternopygus humboldtii, S. lineatus
PD : An elongated fish that lacks a caudal fin. The body is transparent but light brown colored. Sometimes the flanks may have a green iridescence. The backbone can be seen through the body. Two fine, lateral stripes are present; on that runs along the base of the transparent anal fin,and the other located just above this stripe. The head is dark brown to pinkish beige.
SIZE : Males to 18" (46 cm), females rarely exceed 11" (28 cm)
SS : Other
Eigenmannia species
S : bottom, middle
HAB : South America; underneath islands of floating meadows in flood plains in the Amazon basin
TANK : A tank measuring 48" (122 cm) with a capacity of 55 gallons (209 L) is recommended. Plant the tank heavily and use a cover of floating plants to diffuse the lighting. Provide plenty of hiding places among rocks, wood, and pipes. This species prefers "old water."
WATER : pH 6-7.5 (6.9); 4-15 dH (10); 73-82°F (23-28°C)
SB : A peaceful Knifefish that, unusually, should be kept in groups. A social structure will be formed with a dominant fish and weaker members. Combine with peaceful species too large to swallow.
SC : Loricarids, Armored Catfish, Doradids, larger tetras, dwarf Acaras, Angelfish, Headstanders
FOOD : Live; small fish, snails, crustaceans, earthworms, mosquito larvae,
Tubifex ;tablets, acclimated individuals may accept flakes.
SEX : Males are obviously larger and have a larger caudal penuncle.
B : Stimulating the rainy season helps initiate spawning. Use soft water (2-4 dH). Spawning takes place in the early morning hours. Eggs are laid in small amounts during each pairing, which lasts from 3-6 hours. In all, 100-200 eggs are usually laid on roots of floating plants. Remove eggs and transfer them to rearing tank. Raise the fry on
Artemia nauplii.
BP : 9.Breeding is very difficult.
R : During spawning, the Glass Knife Fish emits electrical signals. These electrical signals can be heard with the aid of an amplifier, a speaker, and two electrodes. These signals produce songs that are thought to helpfish to pair up.Use a good water conditioner. Sensitive to new water added during water changes. Prefer water that has been standing for a while.
DC : 6. This nocturnal species requires a diet of live foods and is sensitive to changing water conditions.
