You are just looking at a step they no longer consider needed. Be sure to continue to rinse thoroughly after recharging.

Excellent! Ferraris (in his book mentioned in the OP) was particular about certain characteristics of these catfish ("sierra cats" as he called them), feeding in groups of hundreds, sifting substrate of mud and sand, and moving to lower depths during daylight (as opposed to nestling under logs or ...

Hi all Nice! I received a reply from one of the authors of the abstract (Mark Sabaj Perez) who confirmed that 300MM is incorrect, that 550MM is correct, and that the specimen he examined was obtained from Dr Carl Ferraris. He agrees it may in fact be the skeleton from the one in the picture. Cheers

Just an update. The three specimens in question were all found in the rio Carapo (trib rio Paragua) by Ferraris on 2/24/90 (see page 201 for specimen sources.) It's possible that one of the specimens is the one in the picture. Specimens, size are AMNH 91330D 550MM ANSP 187157 500MM AMNH 90798 302MM

Well, that's one of the best written queries I've seen in this forum for a while! Great work. :-) OK, so are you suggesting I increase the max size SL to 550mm with a note to explain that the Orinoco species (and thus that which is most currently likely to be encountered by aquarists) is the only ...

He also did an extremely detailed work on the Doras cats around Venezuela and the Amazon where he captured and measured many Doras cats. Doras Carinatus is listed there. He found 21 of various sizes, but the 3 largest of the 21 all came from the Orinoco (which are also the only 3 he found there ...

1) Are all of these catfish Doras Carinatus? 2) If so, you'll note that 1 of the fish (the extra large one) is clearly not 30 cm. 3) Carl Ferraris had these pictures in a 1991 Book on South American Catfish under the name Doras Carinatus. (pages 117-118, Catfish in the Aquarium, 1991, Tetra Press ...
