How long do gouramis live
Dwarf and honey gouramis live about 4–5 years; pearls and larger types 5–7. Good water and a varied diet push the upper range. The main risks are DGIV in dwarfs, fin rot from poor water, and bullying in overstocked tanks. A planted, calm tank with stable parameters keeps them healthy.
Tank and the air-gulping habit
A 10–20 gal (40–75 L) tank suits dwarfs; larger gouramis need more. Keep the surface unobstructed by floating plants over the whole top — they must reach air. Low to moderate flow and warm water (72–82°F / 22–28°C) suit them. Gentle filtration; strong currents stress labyrinth fish.
Diet and bubble nests
Feed omnivore flakes or micro-pellets plus frozen/live foods (brine shrimp, daphnia). Males build bubblenests when ready to spawn and guard them fiercely; remove females after eggs are laid to avoid harassment. Overfeeding causes bloating — small meals, once or twice daily. No tight lipped tank mates that nip their long fins (especially males).
The DGIV warning
Dwarf gouramis have a high rate of iridovirus that causes wasting and sudden death; there is no treatment. Buy only from trusted breeders, quarantine, and avoid obviously thin or lethargic fish. The pearl and honey gouramis are hardier alternatives if you want the look without the risk.
Beginner mistakes to avoid
- Buying a sick dwarf gourami — DGIV is common and untreatable.
- Covering the whole surface with plants — they cannot reach air.
- Mixing with fin-nippers — gouramis lose their tails.
- Strong current — labyrinth fish hate flow.
