Re: Rio Tefe

Vern,

This is an update on what I've previously reported
on A. sp. Tef� (I think Erik
has it recorded on the Krib web site). It now
appears that there are only 2
agassizii-complex species from the Rio Tef�, one
is a standard aggie and the
other is a separate species (A. sp. Tef�). I have
been told by other German
hobbyists that the breeding experiments used by
Peter & Martin Hoffmann not only
could not be repeated, but that the Tef� I & II
forms readily interbreed for
other hobbyists. This contradicts the Hoffmann's
published report indicating 2
different species of Tef�.

Randy's photo of Tef� shows  the many wavy
horizontal lines that
characterize the Tef� II form of the specie. The 2
forms of this species can be
easily separated by the pattern of horizontal
stripes on the flanks. Tef� I has
stripes composed of dark pigment only on the front
edges of the scales. The same
stripes in Tef� II are formed by black pigment
surrounding the entire outer edges
of the scales. Crossing the 2 forms reportedly
produces only Tef� I type
horizontal stripes, so the type II form must be
recessive. Color forms are in the
eyes of the owner. In Koslowski's 1994 article on
Apistos of the Rio Tef� he
pictures a red backed and a white form of what
appear to be Tef� I and a yellow
form of Tef� II. He doesn't distinguish between
the 2 forms. Matsuzaka's book
Aquarium 2300 Atlas shows a yellow & a blue Tef�,
both Tef� II.

That's the latest info that I have.
