Edison, I hope the information below will be of help to you. I 'pasted' the references from my file that already had been issued on this list. Metronidazole Use at 250 mg/10 gallons of water8 or 7 mg/liter1. Three administrations every other day, with a 20% water change before each dose is given. Pre-dissolve the compound in a cup of aquarium water, and then pour it in the aquarium. (extract from the site below) Dionigi has a excellent article on most of the health problems we encounter titled "Symptomatic treatment of common Discus diseases" which can be found at http://aquaworldnet.com/awmag/symtreaten.shtml ,http://aquaworldnet.com/awmag/symtreaten1.shtml and http://aquaworldnet.com/awmag/symtreaten2.shtml. The last part contains details of the use of flubenol as a treatment. Regards, Helen > Does anyone know how to administer Metronidazole to treat intestinal > parasite of Dwarf Chiclids?
