The mystery of the locality code explained<br />
Killifish names often have strange-looking abbreviations appended, for<br />
example BDBG 04/15 “Lolo1” or LEC 93/4. These codes make it possible<br />
to keep different populations separate and avoid mixing them together<br />
in the aquarium hobby. These codes are assigned at the discretion of the<br />
collectors and are not subject to any particular rules. They contain fundamental<br />
information and also permit the addition of further data. Thus<br />
BDBG stands for the two collectors Bogaerts and de Bruyn, and the G<br />
represents the country of Gabon; 04 indicates the year 2004 and the 15<br />
stands for collecting site no. 15. “Lolo1” refers to the nearby settlement.<br />
Anyone working with these fishes can find out, on the Internet, for<br />
example, who is behind the codes. Sometimes you can find very precise<br />
additional habitat data in the process, including the GPS data of the location,<br />
the time of capture, and other details such as water depth, current<br />
speed, air and water temperatures, water parameters, and other fishes<br />
caught there. Because the codes describe collecting sites, it may well happen<br />
that two different, but syntopic killifish species bear the same code if<br />
they were caught together at the same site.<br />
How far the information goes is at the discretion of the collector. As<br />
can be seen from the other articles here, the taxonomy of Aphyosemion is<br />
still unresolved, and it is likely that we can expect name changes and new<br />
species descriptions. Names may be altered, but locality codes remain unchanged.<br />
In this way it is possible to tell what fish was originally involved,<br />
even after a revision.<br />
Information on Aphyosemion and other killifishes can be found on the<br />
Internet at the American Killifish Association (www.aka.org) or the UK<br />
Killifish site (www.killi.co.uk). For online purchase directly from breeders,<br />
most of them in the United States, www.AquaBid.com usually sells<br />
various killifish and killifish eggs, including Aphyosemion spp., at auction.<br />
deep but may also be very narrow and shallow. Popular<br />
haunts are shallow areas with trailing bank vegetation or<br />
submerged grasses. Depending on the region,<br />
these areas may also be shaded by surrounding<br />
trees. Still, a planted aquarium is appreciated.<br />
But cover in the form of bogwood and oak<br />
leaves is equally well accepted. Caves may be<br />
investigated out of curiosity, but not deliberately<br />
used.<br />
Bright lighting can cause the fishes to become<br />
more timid and their splendid coloration<br />
won’t look as good. If the vegetation is feathery,<br />
there is even a possibility that the fishes<br />
will spawn in it and occasional juveniles will<br />
survive. If this happens regularly and you want<br />
to keep the young, you should remove the larger<br />
youngsters—they often pose a greater danger to<br />
their younger siblings than the parents do.<br />
It should be obvious that an open-topped<br />
aquarium is out of the question because of the<br />
tendency of the fishes to jump. You can, of<br />
course, allow the surface to become<br />
overgrown with floating plants in<br />
order to limit the jumping to some<br />
extent, but this offers no guarantee<br />
that jumping won’t occur.<br />
Smaller aquariums with a volume<br />
of 6–7 gallons (25 L) are also fine if<br />
used as species tanks.<br />
Suitable starter species<br />
There are many species that could be<br />
listed here. I would suggest first and<br />
foremost the coastal species—that is,<br />
those that need to be kept warmer<br />
and will tolerate tap water. The problem<br />
is that with a few exceptions,<br />
they are not available in the trade.<br />
Aphyosemion australe and Aphyosemion<br />
striatum are well known and<br />
available. Aphyosemion marginatum<br />
and Aphyosemion primigenium are at<br />
least as attractive, but are not common<br />
in the trade.<br />
In my opinion there is a further<br />
reason why Aphyosemion species are<br />
not often found in the trade: wildcaught<br />
specimens are rarely available.<br />
As a result, the killies don’t come to<br />
the attention of the public and are<br />
regarded as demanding and exotic.<br />
The deliberate breeding of Aphyosemion<br />
is relatively time-consuming, and<br />
large numbers cannot be produced<br />
without expense and effort. So killifishes<br />
in general, and Aphyosemion<br />
in particular, have for many years remained hobby fishes<br />
reserved for enthusiasts.<br />
Neolebias unifasciatus is found together with Aphyosemion.<br />
