Quicky Question - Lifespan Of A Killifish?

[Spishkey]

im just wondering how long they usually live for? i bought a group 2 years ago and sadly these past few months they seem to be dying off, im not sure if its old age creeping in or a disease? they show no signs of illness apart from looking tired and not hanging so straight against the top of the water anymore (their back end seems to dip a little) no other fish are effected just the killis. im down to one last lone male (who looks in great health) and wondered if its just an age thing...am i ok to get some more to bump the numbers back up, he looks lonely up there at the top!

I think it depends on the type? Some are annual and others I think a max of 3-4 years? So old age could be likely.
