will commence with information about this livebearer
(Priapella intermedia /Alvarez & Carranza,
1952/), you will directly find some obscurities.
The first of them is the Czech name; varied authors
mention different species (czech) names blue-eyed or
green-eyed. Personally, I tend towards the first
option, because blue color corresponds to the real
color of its eye.
obscurity is its unavailability, or if you like –
rarity. “Priapella intermedia is very rare species
of livebearers”, stands in Dokoupil’s Livebearers
Opponents of this statement are actually any other
resources available for me, which mention high
number of habitats.
with frequently mentioned delicacy we can’t agree
without any doubts – it was found in rivers, lakes
and stream pools in temperatures about 24-32 °C, pH
7,4-9,6, dGH 11-44 and conduction 50-680 µS (Novák&Hoffman,
Wischnat). The only one, on which agree every
resource, are almost zero values of content of
nitrogen fusions. Now, this is the only one, which
we can never provide them. But after my experiences
with multiple breeding in several generations, I can
maintain that Oaxancan blue-eye is pretty
tolerant to this problem.
advisable for breeding is the tank with volume about
60-80 liters, mediumly ingrown, not much
illuminated, with free bigger part of the upper
third of water column. They are good and fast
swimmers. They are also very good jumpers! Males
mature after 5-6 months and reach 5 cm; females have
their first young at the age of 7-8 months and reach
about 8 cm. After 28 days of very discreet gravidity
incubates, regarding to the size, unusually small
amount of the young (about 7 mm). The adults aren’t
noticing them. The litter of fifteen young is very
strong; the usual average is about ten pieces. They
grow very quickly while they have enough food. The
litters are perfectly periodic, in one-species tank,
and the amount of the young fluctuates only
slightly. I observed with my friend dr. Chaloupecký
that the females don’t get in calf in fish-saturated
tank. It is enough for them to take away a few
pieces and the litters continue after one month.
rather prefer dry flaky food, scratched meat, living
or frozen bloody worms than other kinds of the
living food. It is necessary to feed them at really
small pieces, because the food, which felt to the
bottom, stays without notice. So, it can feed even
the large amount of water snail.
most beautiful species of untold family (bonita,
compressa, intermedia, olmecae). In small
shoal, it is really lovely inmate in aquarium and
even in spite of the noteless ochre color it will
hold everybody’s interest immediately on the first
occasion with its expressively blue-shining eye.
