HOW TO: Hatching your eggs

Please note: you will need to have access to boiled egg yolk or an infusoria culture to feed your fry. You will not be able to feed your fry typical fish food (flake, pellet, baby brine shrimp etc.) as their mouths are too small. 

What can I expect and when will the eggs hatch?

Your package will include 50+ eggs. Eggs have been collected from the brood stock fish at a maximum of seven days prior to dispatch. Eggs typically hatch 10 days after they have been laid; this means eggs should begin to hatch within a few days after you receive them. 

In what conditions should I keep the eggs to promote hatching?

Eggs should be moved into an aerated container with 5-10L of water as soon as they are received. Water must be newly conditioned and not water from an old tank. Old tank water has the potential to carry fungus, which can infect the eggs and stunt hatching. A 3/4 full bucket with an air stone works great! Aeration should be small, gentle bubbles, so the fry can swim freely and without difficulty. Eggs will hatch provided they are kept in ample conditions (21-26°C). Eggs kept in warmer temperatures will hatch more quickly, but will require more regular feeding at an increased dose. 

How do I feed the new fry?

After a few days, fry should be visible, swimming at the top of the water. Fry will hatch with a yolk sac, which will provide them with nutrition for a very short amount of time after hatching. Therefore, it is important to continuously check for fry everyday, to ensure you are able to feed promptly following hatching. 

Once fry are free-swimming, hard-boiled egg yolk can be used to feed. The yolk should be crushed and mixed with water from the bucket to create a 'golden milk'-like mixture. No big chunks should be visible in this mixture and it should be entirely smooth. Over the surface of the water, drops of this mixture should be distributed sparingly (be sure not to overfeed!). The more often the fry are fed using this method, the better. Three times a day is ideal. 

After the first fry, fry should continue to hatch for ten days. There will be a size difference, but continue to feed the egg yolk during this period. After ten days, the oldest fry will be big enough to eat baby brine shrimp; introduce this to the fry, but continue feeding egg yolk for the smaller fry. Continue until all fry are able to take baby brine shrimp. 

Some people may use dry food to feed fry after egg yolk, but we have experienced the best results and most prolific growth (with a high survival rate) when weaning the fry onto baby brine shrimp.
