describers Who described all these species? Here is a list of all the people who have defined killifish taxa, how many species they described and how many of them are considered still valid at the present time. easy The easiest killies This is rather subjective and by no means will you have guarenteed instant success with the killifish on this list, but for the most part these are the killies that most people find the easiest to maintain and reproduce. frequency Frequency of names Some species names show up more than once, and while the name of the genus must be unique, the species name need not be so. Here you'll find a list of the more commonly used species name. hard The hardest killies The same applies here, while by no means will you find all the killies here near impossible to keep or breed, these species tend to give even the most advanced hobbyist fits and while maintaining them is not particularly difficult in most cases, breeding them, at all, or in numbers more than a handfull represents rather a challenge, to say the least. In some cases, this may be a function of time; Psudoepiplatys annulatus was once regarded by very accomplished hobbyists as a very difficult species, yet there are people today who breed them by the hundreds. history Historical statistics Here you'll find various tidbits of information regarding the history of killifish taxonomy, such as when species were described and what the earliest and most recent taxa are.

incubation Species with the longest incubation times Here you'll find a list of the species, in order, that have the longest egg incubation times. populations Number of populations of killifish genera Part of the reason killifish taxonomy is such a mess is due to the fact they are so polymorphic; there are species and subspecies of killies and in turn, different populations of these. Sometimes diferent populations look very similar, sometimes they are so different they have frequently been mistaken for other species. Here you'll find a complete listing of the number of known populations to date of all killifish general. In reality there are actually more thanis indicated here due to commercial imports, but since it is impossible to determine the origin of these, they cannot be included here. size Median size of killifish genra Here you'll find a table of the minimum, median and maximum size of all the known genera of killifish. species Listing of species All List of all known killifish species By country Genera by country Density Popultaion density by country Genera List of all killifish genera Here you'll find various lists of species broken down by various orderings.
