Bill Drake wrote report in BKA newsletter No.530,
November 2009. This concerned population GEMC 06 / 7. A pair was set
up in ater of pH 6·5, Hardness 2°, filtered for 24-48 hours.
Java moss & mops were added. After 14 days about 20 eggs were collected
but only 50% hatched out. No more eggs were found after this & the
male later died. From the 10 hatched eggs only 8 survived to adulthood
which turned out to be 3 males & 5 females. Young + the original
old female were spawned. A pair would give about 20 eggs in a week.
