Thick-lipped gouramis are calm, slightly shy gouramis: males are marked with thin red and blue stripes, females are silvery. Keep one, or a male with a female, in a planted 20 gallon or larger tank with floating plants and gentle flow, away from fin nippers that pull at their thread-like fins.
Diet: Omnivore: flakes, small pellets, bloodworm and brine shrimp. Fish food types compared · how often to feed.
Where they swim: Top of the tank.

Common thick-lipped gourami problems
- Barbs and other fin nippers damage their thread-like fins.
- Shy in a bare tank; plants and floating cover bring them out.
Test the water first whenever fish look unwell: see what your readings mean, then match the symptom. For disease, a vet who treats fish can diagnose it and advise treatment.
