One of the tiniest livebearers

Overhere some pictures of one of the smaller livebearers called "dwarf merry widow" (Phallichthys tico) from Costa Rica. Adult size is similar to least killifish (Heterandria formosa) and Teddy tigers (Neoheterandria elegans). And it's also a superfetative livebearer species like the other two mentioned dwarf livebearers.

No, I didn't catch those myself. It's a species that does occur in certain households of private breeders around this globe. It's not a particular species that would be offered through retail. Some stores may sell them as a specialty.

A short video of some of them
And a video in combination with dwarf swordtails (Xiphophorus pygmaeus)
