This has been a good winter for spawning
activity. I currently have fry from two populations of A. guttata, two
populations of A. hoignei, and from my unidentfied pertensis-like apisto ( Mike
I will send you a photo). The pertensis like fish is quite sensitive to pH
for survival of the fry. When I allowed the pH to get up around 6.5, I had
several batches of eggs hatch but the fry soon disappeared. When I keep
the pH around 5.5, the fry do well.
I have also made changes in the gravel in some of
my tanks. I switched from coated gravel of about 5 mm to Lone Star #3
sand. This has not only improved the looks of the tanks but the fish are
able to dig the pits to move the fry around to and also pile up the sand to
block the entrance to the spawning caves when eggs or fry are in the
caves. I have not had problems with algae coating the surface of this sand
as I did with finer sand.
