To expand on Lee's response...

Even socalled non-annuals can have their eggs incubated 
on or in peat. For example: A. australe's (AUS for 
short) eggs can be incubated in peat for 4 to 5 weeks to 
yield perfectly uniform hatches. The eggs also have a 
higher survival rate.

The plus with water icnubation of non- and semi-annuals 
is that the incubation time is much shorter (as much as 
1/3) but as Lee says you end up with a fry ot 2 hatching 
every day till you have several tanks of fry all of 
different sizes and all looking for a smaller simbling 
to eat... These problems are non-existent with peat/dry 
incubation.
