Many wild caught fish are 'infested' with various parasites, bacteria, etc., which are not adequately eliminated from the fish during its drip to a persion via wholesalers, shippers, jobbers, fish stores. The 'pathogenic' explosion which can occur in highly stressed fish can, and do take their toll. Not to even mention the 'tuberculoid' possibilities with fish. A systematic treatment of IMPORTS is often necessary, just to get them survive while trying to 'destress' them. Some fish are more tolerant, others much less. But if you ever looked inside a wild fish from SA or CA, you probably wouldn't want to eat fish again... >---------- >From: anggrek@juno.com[SMTP:anggrek@juno.com] >Sent: Sunday, February 08, 1998 8:24 AM >To: apisto@majordomo.pobox.com >Subject: wild-caught fish > >there was a recent thread about wild-caught fish in this list. i have >noticed that many of the wild-caught fish from south america tend to live >in your tanks or at the shop for several weeks but inevitably waste away. > i wonder if this is due to the fish's inability to adapt to a new >environment and new food, or other causes. > >i recently found my mystery trumpet-nose marbled knifefish dead. this >unidentified gymnotoid had lived in my 55 gallon for about 4 months. its >body shows no sign of disease or starvation. it obviously did eat >something while there otherwise it wouldn't have lasted this long. the >tank in question is very stable, heavily planted and houses nannacara >anomala, apisto nijsseni, catfish and tetras. > >any thoughts on the subject would be appreciated. > >tsuh yang chen, new york city > > >------------------------------------------------------------------------- >
