Yes, SJO can be water incubate. It will take some eggs 15 days, some 20
days, some a month, some longer to hatch out. Really not a great option for
a species as voracius as SJO. I ended up with only one fry from that batch
with in a month, but that biggest one grow real quick, alright. I guess I
don't have to tell you where all other smaller fry gone.
The way I now ended up with is to water incubate them in Acriflavine
solution for a week. I let all those bad eggs gone bad then transfer all
the good one to peat incubate for another month before I hacth them out.
The fry size is a lot more closer than water incubate that make taking care
of them a lot easier. Oh, I use sinking mop and I hand pick my eggs with
out any problem.

out either the parents or fry. The parents would be easier though. As stated
in another email, 4-6 weeks on incubation depending on temperature.
I recall there being debate over the care of SJO eggs while water incubating
them. They die off after a day or two in my fishroom, I think that they need
to have fresh water changes and aeration to survive. I have since made it
habit to peat incubate my SJO eggs, and even then, the yield is very low in
relation to other FP species that I breed. I have never had success myself
with leaving the eggs in the tank, they die off, unless I remove them and
keep them in damp peat.
I have seen reports of breeders who could collect several hundred eggs, yet
have zero hatch. I too have a bad yields.
Anything I can do to up the odds the better, I am still trying to figure
this one out, but I have ruled out water incubation as a viable option. I
also never touch the eggs with my hands. I now get many more fry every week
from my fish. I also found that as the fish matured the fertility increased,
eggs were not crushed by removing the mop from the tank and there were fewer
white eggs in the mop. Now I have too many sjo's and dont know what to do...
