Emeraldking-aquatics livebearers

Phallichthys

Phallichtys fairweatheri
This livebearer is als known as "Banded merry widow" but also as "Picotee livebearer".
Phallichthys fairweatheri can be found in slowly flowing and standing marshy peripheral area of rivers in countries like Mexico to Guatemala and Honduras.
It's a gray bodied livebearer with some yellow vertical markings on its body and also in the fin area there are some yellow markings to be noticed.  Like most phallichthys breeds, the male has got an extended gonopodium. One of the phallichthys breeds that has a less extended gonopodium is the phallichthys quadripunctatus. 
After a gestation of approx. 3 - 4 weeks a number of 10 - 30 fry will be dropped. They'll size up to approx. 3 - 5cm.
 
 
Phallichthys quadripunctatus
This small livebearer is also known as the "Four spotted merry widow". "Four spotted" simply because there are in general four black (sometimes three or five) spots on both sides of the fsh.
This species is endemic to Rio Sixaola in Costa Rica. It's not a very profilic livebearer for after a gestation of 4 weeks 5 to 20 fry will be born. From own experience the average number of fry will be 10-15.
Comfortable water temp rates are between 20°C and 34°C. Which makes this  an easy fish to keep.
And because of their size, they can also be kept in smaller tanks. Furthermore, they're friendly fish . Even to their own newborn offspring.
 
 
Phallichthys amates pittieri
This livebearer is also called "Orange-fin merry widow", "Iridescent widow' and "Olomina"  and are to be found in inland and mountain streams in Costa Rica (Cahuita) and Northern Panama.
The species does look similar to the Phallichthys amates amates but is really smaller in size. They'll size up till 3 - 4cm in length. After a gestation of 4 - 5 weeks they'll repoduce a number of 10 - 30 fry.
Also with this phallichthys breed the males have an extended gonopodium.
 
 
Phallichthys tico
A small livebearer from Costa Rica is the Phallichtys tico also known as the dwarf merry widow. This species is to be found in still and turbid waters (mostly swamps and backwaters). Further on they occur between the floating plants of the former Lago Arenal and Lake Nicaragua (mostly along the shoreline). And they're also known from the tributaries of Rio San Juan.
This is a peaceful small livebearer that can be kept at temperatures, ranging from 22°C - 30°C. They prefer neutral till hard water. The body is brown till greyish based with 8-10 vertical bars on each side. These bars are more present with males and young fish. In some way the bars dissappears when a female comes to adulthood. And with both genders, the dorsal has got a black seam. They'll reach up max. 3,5 cm.
When kept in a school, this omnivore likes to shoal. But if you'd like to keep them as a couple in a tank, they'll do just fine without any other members of their own kind. When it comes to reproductions, the batches are small in number. But in general all fry will grow up till adulthood for the parents won't chase nor eat their fry.
