🥚
24–48 hoursStage 1
Bubble-nest Eggs
Male builds bubble nest and guards eggs/fry.
Anatomical Highlights:
- •Surface bubble nest
- •Fast hatch
Ecology: Paternal care nest.
🐟
0–3 monthsStage 2
Fry
Tiny fry; labyrinth organ develops as they grow.
Anatomical Highlights:
- •Developing labyrinth organ
- •Fin growth
Ecology: Surface-oriented micropredator.
👑
4 months–4 yearsStage 3
Adult
Males often long-finned and territorial.
Anatomical Highlights:
- •Labyrinth air breathing
- •Long fins (males)
Ecology: Shallow-water insectivore.
