Part 4/5:
In the stagnant waters where the Siamese fighting fish dwell, oxygen can be a scarce resource. However, the ingenious design of the bubble nest provides a critical advantage. The eggs, safely nestled within the nest, receive adequate oxygen from the surrounding bubbles, enabling them to develop properly. This adaptation not only enhances the chances of survival for the embryos but also reflects the species' remarkable evolutionary strategies in response to environmental challenges.
