Discus vs Licorice Gourami

How the Discus and Licorice Gourami compare on care, size, water and temperament, and which fish suits your tank.

By Updated

TL;DR, Discus vs Licorice Gourami

The Discus and the Licorice Gourami come up together a lot when people are choosing a fish, and they are close enough to weigh side by side. Both are happy somewhere around 28 to 28 °C and pH 5.5 to 5.5, so a single tank can suit either one. The Discus is the more forgiving of the two, which matters if this is an early tank, while the Licorice Gourami rewards a bit more attention. If tank space is tight, the Licorice Gourami needs less room to feel settled; give the Discus the nod when you have the litres to spare.

What to plan for

  • Tight temperature windowThe overlap is only 28–28 °C. Heater stability matters more than usual; consider an external controller.
  • Narrow pH overlapTarget pH is 5.5–5.5. Test weekly; use buffered substrate or remineraliser to keep it stable.
  • Discus schools, stock at least 6You've planned for 1 discus. Discus need a group of at least 6 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
  • Demanding species presentDiscus, Licorice Gourami are difficulty 4+. Stable parameters and weekly maintenance are non-negotiable.
  • No bottom teamNo bottom-dwelling fish or shrimp. A small group of corydoras or a shrimp colony picks up leftover food and keeps detritus in check.
  • 67% of your fish swim in the midHeavy concentration in a single zone. Spreading stocking across all three levels makes the tank read fuller for the same bioload.
