保育水槽  Hatching aquarium

Protection of baby killifish:
In May, when the aquarium temperature goes up and the sun gets stronger, the killifish eggs start to get hatched.
The enemies of the newly hatched killifish babies are parent killifish and mosquito larvae.
The parent killifish can’t distinguish their babies from their food because they are too tiny. And the mosquito larvae eat the baby killifish as food.
To prevent the baby killifish from being eaten by their parent fish, the waterweeds and the beds on which the eggs are laid are moved into another hatching aquarium, which is covered by the mosquito net not to have mosquito larvae in it. 
We can’t see the newly born killifish with our naked eyes, but in a few weeks they grow a few millimeters in length and we can see them swimming.
