Len/Geo <> WROTE:<<<<< Date: Sun, 07 Dec 1997 16:39:33 -0500 Subject: Apisto Death 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?>>>> Is this fish also breathing heavily? Since water chemistry is OK, and a second fish is affected, there is probably an infective pathogen around. It's very unlikely that it is a bacterium: a very common cause for rapidly fatal diseases are pathogens like the agents of velvet or Ick (which do not always cause visible white spots). In my opinion, your best first-line remedy is formalin+malachite green (I saved a several apisto and laetacara fry with it). The product I am familiar with is Rid-Ich+ by kordon, at 7 ml/10 gal, on day 1, 4, 7, 10 and water changes on day 13. Add an airstone, since it will decrease the oxygen levels. Stay away from antibacterials and poorly designed mixtures of various drugs, which often just kill the filter and do nothing on the pathogens! Good luck, and let us know on how it goes. By the way, have you recently introduced some new fish in that tank? Dionigi
