The Red-Tailed Goodeid
Water Conditions- Not Critical. Temp 70- 78 Degrees,
Plants, Vegetable in Diet
Behavior- A better behaved population, best kept in
species only tanks.
Breeding- 5-15 Young every 60 Days.
Size- 2.5 inches
With water that does not get too
warm (above about
76-77 degrees consistently),

fish is about as hardy as a goodeid can get. They breed easily with
broods of up to 20 fish approximately every 60 days.
are large, and easy to raise, taking
baby brine shrimp or even
finely crushed flake immediately.
Like many goodeids, they are
officially considered endangered
in the wild.
Omnivorous, they do best with a variety of dry and frozen
foods, including food with a
They are very active, and will
eat fry given the
opportunity. A heavily planted portion
of the tank for the young
to hide in
may be enough, after a healthy sized population is
established (Separate the gravid female and raise the young
separately to build up your numbers). If well fed, they
should produce more fry than they will consume. Though they
are a smaller fish, and a few will do fine in a 10 gallon
tank, for a colony to grow a tank of at least 29 gallons
should be used.
One important factor to mention is that at a
local university, the department was looking for a species that
overwinter in an unheated greenhouse. They were kept in a 12'
long trout runner, planted with natural vegetation.
The temperatures would fall to 45-50 degrees at times, with
water temperatures of 50-55 degrees overwinter.
A number of species were tried, and this line of
X. eiseni both thrived and
bred seasonally, increasing their
numbers over the three years they were kept this way. A very cold water tolerant
