The Xenotoca eiseni
is a hardy, beautiful, distinctively shaped goodeid that can
range of temperatures, though it does best in the lower 70s.
Fairly prolific, their
numbers will increase even though they are prone to eating their
fry, but they will
do best when the female is removed to a separate tank, and the
fry are raised
separately. Best kept in a colony tank, they are well
behaved with one another.
