  3. Also, take care of the favorable pH of the water, which should be between 5.0 and 6.0 during the reproduction period.
  4. Diet also plays an important role in preparing these fish for breeding. Give them high-quality live food just before spawning. The portions served at this time should be larger than before.

What happens after spawning? Adult spearfish often eat their eggs, after spawning you have to catch them quickly and transfer them to another tank. The sooner you spot the eggs, the greater the chance of a large brood. Small fish start to hatch from the saved eggs within 24-48 hours, and after a few days they can easily swim.
