Re: Notho egg development

[Barry Cooper <bjc3 at cornell_edu>]

I regularly store my Notho eggs in plastic boxes on the floor, where I 
guess they are in the low 70s except when we have heat waves like a coupld 
of weeks ago.

My Nothos regularly hatch many months after the "official" incubation 
period. For example, I recently hatch N. elongatus, N. melanospilus and N. 
jubbi after 9-11 months of incubation. I find this delayed hatching useful 
because it allows me to be able to keep more species.

One possible precaution: With N. jubbi I am having problems with 
predominance of males and I wonder whether temperature of incubation might 
influence that.
