2. Upon spawning, male immediately fertilize the eggs
3. Male is a Mouth Brooder :  Pick up the eggs & hold inside the mouth (parental care); does not eat food for 30-50 days UNTIL babies/embryo can swim on their own
WHY?
- To protect babies from external harm in the environment
- Mouth provides an incubating environment for eggs to hatch
-  Ensures yolk is moving frequently to ensure yolk does not solidify & continue nutrient transfer 

4. Eggs hatch; baby fish (embryo) will still be attached to the egg yolk
- Egg yolk : Source of food/nutrients for embryo, delivered in liquid form through the nutrient delivery tube

Open up the male arrowanas mouth one by one,
- If there are eggs, bring to incubating house for eggs to hatch

2. Incubater simulates the same environment inside the male arowana's mouth;
- Creates the wave to keep turning and moving the embryos 
-> Embryos left inside until it can swim by itself

3. Transfer to fish tank
4. When the arowana can swim stably & sized at about 4-5 inches, inject microchip and document birth certification
