The Scheel Letters

edited by Allan Semeit

These letters were sent out by Joergen Scheel, from Denmark, in the early 1960's. Copies were circulated among hobbyists around the world. This period of time was when killifish keepers began organizing and corresponding with one another. These communications led to the discovery of basic techniques to maintain killifish and helped resolve some of the confusion regarding species identification that existed at that time. Many popular species had been misidentified and were circulating under names belonging to other species. Bear this in mind as you read through these.

The "Letters" are being posted in the sequence we received them. We believe this is in chronological order. The "Letters" were not clearly divided, so we have numbered and divided the information into separate sections as the topic changes. These numbers do not reflect any numbers attached to the original Letters. We have also taken the liberty to correct minor grammatical errors, possibly created when the text changed from one format to another. The intent, however, was to leave as much possible as it was received. We hope that you enjoy these Letters and find them to be educational and helpful.
