Switch Spawning Killifish are simply species of Killifish that can be spawned in either the
Plant Spawning or
Soil Spawning methods. They are just more adaptable. You can try either method with the particular species you are working with and see which method gives you the best results.
Note that when the Plant Spawning method is used the incubation period is usually much shorter, about 2 weeks. But when the Soil Spawning method is used the incubation is longer, up to 6 weeks. The Soil Spawning method can come in handy if you want to collect a lot of eggs and hatch them all at the same time.
Most, if not all, Killifish can be spawned and their eggs collected and placed on top of moist peat moss patties, even the strictly Plant Spawning only types. This sometimes comes in handy if you are having a lot of trouble with fungused eggs. Though with the Strictly Plant Spawners the incubation period remains about the same as normal (2 weeks).

The Blue Gularis is another
example of a switch spawning killifish.
The Killifish hobby is growing everyday and the
American Killifish Association is mainly responsible. If you get bitten by the "Killy Bug", I urge you to join this fine organization. They put out a great publication, "The Journal Of The American Killifish Association" (JAKA) and a monthly Business Newsletter (BNL) that includes a fish and eggs listing of stock for sale by members.
