Re: N. rachovii

Brian,

Thanks for the clarification of incubation times, especially those of eggs
from wild-caught fish. As I had mentioned, Brian has had much more
experience that I have with the latter phenomenon. Certainly for the fish
we collected in 97 in Tanzania, I experienced quite short incubation
periods, as short as 6 weeks in some cases. I collected peat promptly as I
was obviously keen to get some hatches of those fish. On the other end of
the spectrum, I have had good hatches from N. eggersi Rufiji River Camp TAN
95/8 after as long as 11 months. This is a fish that would normally be
regarded as short incubation period, usually about 3 months under aquarium
conditions. Like Brian, I often leave the peat for several weeks, and
expect it is quite anaerobic by the time I collect it. I actually prefer
long incubation periods as it allows me to better control the production in
my fishroom.

Barry
