Killifish – fish species that lives for only one year. Their lifespan is annual because they are born in the ponds before rainy season. Each year these species lay eggs during this dry period. Eggs hatch when rain starts so the adult fish gets exactly a year of lifespan for laying eggs and then end up dying during dry period.
There are very few aquarium shops that are likely to keep these fish. I am sure most of these fish are imported at some heavy pricetag due to their low availability.
You can easily identify these fish species. Male is more colorful and has lot of color variations, whereas female has less color and is more dull in appearance.

Care: If your tank has less hostile fish in it, then there would be no problem keeping these fish. These fish require minimum to no care and they are very easy to take care of in terms of food and other temperature requirement.
Compatibility: Make sure you keep them with fish of equal size. Avoid keeping them with too big or too small fish. Also water and temperature requirements are to be considered as well. They can be territorial among their own species but live peacefully with other species.
Breeding: Avoid breeding if they are kept in small tanks. In order for breeding you definitely need bigger space. You also have to imitate the natural environment in which they lay eggs. So you have to keep them in tank with some rocks and limestone. It is to make them comfortable for keeping the eggs.
Food: Killifish feed off on brine shrimp, blood worms and frozen worms.
If you’re going to purchase them make sure that you check their size. Make sure you’re getting a juvenile and not adult because if you’re buying adult you never know when they are going to pass out.
They’re beautiful fish to keep and you can consider them if you’re thinking of keeping them in tank with other peaceful fishmates.
