It's a cyprinodontoid, also a killifish.  Cyprinodont means "toothed carp"
or maybe "carp toothed".  At any rate, at one time there were 'livebearing
tooth carps' and 'egg laying tooth carps'  then they were split up by method
of reproduction, then it because apparent that live bearing had arisen
several times independently among the tooth carps, so they put them back
together and split them up again differently.  This work was done by Lyn
Parenti, et al, if anyone cares to look it up.

At any rate, it's a killifish, even if it may be more closely related to 
some livebearers than to some other killifish.  Killifish is a vernacular
term, and it works.

The confusion with cichlids may be because unlike almost every other 
killifish, the male looks after the eggs and young fry.  Parental
behaviour is characteristic of cichlids, which have probably been
unrelated to tooth carps for at least 200 million years.

All that said, can someone sell me some American Flagfish (Jordanella
floridae) eggs?  I'm thinking about getting back into killies again.
