Hey Zazz,
They are a great fish and welcome to the world of
Heterandria Formosa the least killiefish.
If you would like information, best thing to do is either A. do a search on my name or B.
Heterandria Formosa . I am one of the Main Members here who actually pushes this fish. They are small and do best only in a species only tank. Also I have learned from my mistakes and would like to pass this info on to others. These guys do not do well with a small filter, sad to say. They tend to get sucked up. They are that tiny. When Lisa stated that she really meant that. The adult males are the size of guppy fry, 1/4 inch long, while the females can attain the max length of 1 inch but most are 3/4 of an inch. They are natives to florida and the South West United States. So these guys are a more cool water fish, so no heater is needed. As filtration goes, I recommend either a sponge filter or Under Gravel, this way you will not loose any fry or tiny adults. But remember like all live bearers they need timely water changes. More water changes more fry being produced meaning a good and healthy tank.
Since these guys are small, they love hiding in floating plant material. I love keeping mine with Horn Wort, hair grass and Duck weed. But any plants will do in this tank. Just make sure they have the room to feel secure.
As for providing food for Fish, I find this a very expensive alternative. They are harder to come by in petstores and tend to be more priced. Hets are not as prolific as Guppies and actually bear their fry differently. Guppies, platies, mollies and so on have multiple births during one day. While the Dwarf live bearer tends to do an assembly line style of giving birth. One fry in different stages in the parent fish and producing many fry but giving birth to one a day.
A great source for ordering them is
through Sachs Aquaculture.
