>>Regarding the your case of "dropsy", is the male gaping at the mouth or >is there any heavy breathing. About a month ago I had an outbreak of this >with my apistos specifically with a female biteaniata and a few nijsseni. The symptoms sound very close to the disease that I was describing regarding my pandurini in earlier mailings with subject "lockjaw". I have seen this in numerous wild caught pandurinis, mostly males. I have a f1 nijsseni who is exhibiting this symptom now. I keep many other types of apistos under identical conditions, and even in the same tank without losing any to this mysterious disease. Ed Pon Milpita, California 95035
