What size tank does a three-spot gourami need?
At least 35 gallons (132 liters). The smallest standard tank that works is the 37 gallon. A bigger tank is always easier to keep stable. We give the size for an adult fish, because the small fish in the shop will grow. Scientific name: Trichopodus trichopterus.
