Food and feeding
Largescale foureyes are always looking for food and need a high protein diet. Supply them with fruit flies, brine shrimp and tubifex. Largescale foureyes will also accept shrimp, mussels and beef heart, they prefer to feed from the surface but will swim to the substrate if required to feed.
Origin
South and Central America.
Sexing
Males have a modified anal fin that develops into a gonopodium for transmitting the sperm.
Breeding
Anableps anableps fertilise the eggs by internal insemination but the strange thing is that the gonopodium of the male can only swing one way so the female has to approach the male on the correct side for mating to take place. These fish are livebearers and the young will accept crushed flake or newly hatched brine shrimp immediately.
Lifespan
The expected life span for Largescale foureyes is 6 years.
Short description
