This is arguably the
most beautiful of the wild Xiphophorus swords. Often a blue sheen will appear in a picture of a fish that makes
it look more colorful than it actually is, but
from the belly back to the caudal fin this fish
really does reflect a blue and red sheen when a light is shown on it. As they get older, some of the males will turn
almost entirely red.
Similar to most swords, this fish does best in at least a 20
gallon aquarium with some water movement and
consistent water changes. Unlike the
X. mayae,
this is not a shy fish (nor is the
X. nezhualcoyotl), and though plants are much appreciated, they are not essential
for this species to do well. When you pull the
females as they become ready to drop, raise the
young until they are large enough not to be eaten, and the population will increase quickly. I introduced an
albino alvarezi to the hobby that was born from
this line, and the albino mutation has been
repeated on a number of occasions.
Females,
depending on age will drop between 10 and 50 fry. An easy to keep, hardy, and beautiful fish. More information
Here.
