In response to Bruce Pedden's post about annulatus; here's my
"how I do it" -:
Please note that my water has a hardness of 50 ppm, a pH of
between 6.5 and 7.1 and contains a teaspoon of salt per gallon.
I use a 5 gallon tank at eye level with floating (Riccia) and
sunken (Java Moss) plants (require moderate light from above) a
small sunken mop and a box filter containing only aquarium gravel
(no cover and no filter material). Adults are fed almost
exclusively live baby brine
shrimp. After a few weeks you will begin to see fry at the
air/water interface. They are quite small (and fast). I siphon
some 50% of the breeding tank water into another 5 gallon tank
set up right next to it with the same plants - no filter. The
plants apparently have enough microorganisms, etc. on them to
give the fry food for the first few weeks. The fry are sucked
out with an eyedropper and placed into the new tank.
Once I get to about 50 fry, I start another rearing tank. (You
should get about 5 fry per day.) When they appear large enough,
I feed live baby brine shrimp. Once about half an inch in length,
I transfer them to a ten gallon tank. At this size, they don't
seem to cannibalize each other but I do cull out the larger ones
from time to time. Seems the larger fry either cannibalize the
smaller ones or depleat their food supply; so I advise against
leaving larger fry in a breeding tank.
Despite this, there still appears to be a fair mortality rate -
perhaps 70%. More frequent sanitary attention on ones part may
reduce such losses.
