Polynemus species  8/12/09
Hi Bob,
The fish you have here:
 http://www.wetwebmedia.com/FWsubwebindex/FWDailyPIX/FWDP%20Arch%201-12/fwpotdarch8.htm
May well be Polynemus paradiseus, a species doing the rounds in aquarium shops in the UK. Priced around £60 (almost $100) a piece. They're a brackish water species, but very delicate. Seemingly, the
> long thread-like fins get damaged when collected, and become sites for subsequent bacterial infections. Perhaps because these fins are so long and thin, aquarists don't notice the infection until it has become systemic. In any case, their track record in aquaria is not good. Quarantining surely important, and quite possibly prophylactic treatment with a suitable antibiotic as well.
Cheers, Neale

Incorrect ID, Loricariid, WWM  7/12/09
Hi guys.
You have an interesting site and I've enjoyed looking through the Fresh Water Desktop Archives.
Just thought you'd like to know i believe there is an error in Archive 8.
<Oh?>

The Photograph at the bottom is listed as Pseudacanthicus sp.
But is in fact Pseudorinelepsis genibarbis commonly called "Orange Cheek Pleco" more information on this species can be found here:

<Ah, good catch! That's my fault I suspect; Bob often sends these freshwater fish photos to me, and I do my best to name them, though in this case, apparently incorrectly. Apparently, a good indication of
Pseudorinelepsis and its allies when compared to most other Loricariids, including Pseudacanthicus spp, is the plain circular iris as opposed to the omega-shaped iris usually associated with Loricariids. That indeed matches the fish in Bob's photo, so your identification certainly looks good. So I've learned something today!>
Keep up the good work
