Marbles smaller than 0.25 inch diameter should not be utilized, as frightened fish, diving among them occasionally gets wedged.

An additional form of trap, preferable to marbles, is glass or Perspex bars wired together with soft lead wire to form a frame which you are able to raise about an inch off the bottom, and so leave lots of room for inspection.

Sexes should be separated a week prior to breeding. Introduce the female a day prior to the male. A higher percentage of fertility will probably be maintained if 3 males are utilized to one female. If, nevertheless, the female appears to be worried by too a lot attention, it is advisable to remove one male and leave only two.

The breeding temperature should be between 72°-77°F. The eggs are non-adhesive and hatch in two days, and also the average number of eggs per spawning is 200.
