fins Posted October 10, 2004 Author Report Share Posted October 10, 2004 What is a non-annual old world killi, what is a non-annual new world killi, what is a annual new world killi and what is a annual old world killi. My guess is that old world killies are from africa and new worlds are from America. Is that correct? Quote Link to comment Share on other sites More sharing options...

A killiefish from Africa (there are none elsewhere in the old world that I can think of right now) with a long incubation period due to their habitat drying up for an extended period, Nothobranchius are a classic example. > My guess is that old world killies are from africa and new worlds > are from America. Is that correct? Simplisticly, yes. Andrew. Quote Link to comment Share on other sites More sharing options...
