A gourami lives for three to five years. Depending on the species, however, certain gouramis can live longer. For example, pearl gouramis have a lifespan of five to eight years when provided with proper tank conditions and a healthy diet.
Here are some things you can do to prolong their lifespan and keep them healthy:
- Provide them with ample swimming space
- Avoid overcrowding the tank
- Provide them with plenty of decorations, plants, and hiding spots
- Feed them a healthy and varied omnivore diet
- Maintain their ideal water conditions
- Clean the tank and change the water regularly
- Avoid housing them with aggressive and nippy tankmates
