Hi folks, A few weeks ago I posted the ill-health of my newly acquired Apistogrammoides. After 3 super dose treatments of metronidazole (1000 mg/12 gal. tank), with water changes and carbon filtration between treatments, I think I can safely say the remainder of my group will survive. 2 of the 8 passed on to holier waters early in the process, both males curiously. I think the Paragon did them in, as soon as I applied chemical filtration after a paragon treatment, the remainder started the upswing. Avoid the shotgun medication approach! All fish are now feeding/fighting/excreting regularly and one female is YELLOW- courting the male whenever he passes by her pot. Thanks to all those who offered their suggestions for treatment. - - Steve Waldron
