On Sun, 07 Dec 1997 George wrote My female apisto.cacatuoides died yesterday. She had no visible sign of disease. I did check ammonia, nitrate, nitrite.. all`s fine. Still have the male in the same tank. He stays on the bottom, hides alot, don`t see him eating and does have Clamped fins. Is this some sort of bacterial infection? Is there anything I can do? Next time try Formalite 1 from Aquatronics. Should do the trick. Prevent and controls the following: Protozoan parasites on Fish Ich(Ichthyophthiris) Velvet Oodinium Shimmy Cryptocaryon Collapsed Fins and Listlessness White Body Patches White Spots Trichodina Chilodonella Do not use on scaleless FISH!!! Hope this might help. Phil Ryti rytireefs@juno.com
