<< Subject: Re: Crosocheilus species
I finally got a look at the three Crossocheilus specimens featured
in Robert's "The Freshwater Fishes of Western Borneo." They are
C. cobitis, C. oblongus, and an undetermined species. The pictures
aren't great; however, C. sp. undet. outwardly resembles a SAE
both from the description and from the photo. It has the sharply
defined zigzag black lateral line extending into the caudal fin
nearly to the end and a single pair of rostral barbels. I cannot
tell whether the back has the reticulated pattern. The specimen
is 50 cm long and obviously young from the large eyes. The author
does not label it C. siamensis; rather, he suggests that it may
be C. oblongus var. nigriloba. The year of publication was 1989.
I wonder which Crossocheilus species, or regional varieties
thereof, the Indonesian wholesalers are shipping. Does this mean
that there could be a SAE look-a-like or subspecies with its own
particular eating habits derived from local conditions going
under the SAE banner? Maybe there is a difference between a
"foxy lady" and an "algae-eating shark."
By the way, the photograph of the specimen of C. cobitis
described by Robert does not entirely resemble that which
appears in Baensch Atlas II under the same name. Anyone
surprised? To be fair, taxonomic features no doubt take
precedence over appearance when it comes to determining species.

Hey Dave, hope that's 50mm, not the half a meter minnow that said "I want
Have you seen the piece by Petru Banarescu, 1986. A review of the species
of Crossocheilus, Epalzeorhynchos (sic), and Paracrossocheilus (Pisces,
Cyprinidae). Travaux Du Meseum d Histoire Naturelle "Grigore Antipa". v. 28,
141-161. In examining specimens and pix on the west coast (U.S.), I peg the
more common non-SAE as Paracrossocheilus vittatus... tho we do have 'the real
thing' here as well.
Anyhow if you can't the above ref. and would like a copy (if Coke (tm)
doesn't have me locked up already), I'll send a copy along with a xerograph
of a pop. pc. I penned for the hobby mag.s on the ish of who's who and
Re the apparent diff. twixt Robert and Hans, they may well be the same
fish species as far as I can tell.
