Health & Common Diseases
Key risks, vulnerability factors, and veterinarian-reviewed treatment guides.
Dropsy (Pinecone Disease)
Bacterial fluid buildup often triggered by metabolic stress, sudden ammonia spikes, or low temperatures.
Velvet Disease (Oodinium)
Photosynthetic dinoflagellate parasite causing fine gold-rust dust on skin and gills, clamped fins, and flashing. Cured via 5–7 day blackout, 28–30 °C heat, and medication.
Description
The Sparkling Gourami (Trichopsis pumila) is a captivating 3.5 cm nano labyrinth fish famous for two traits: rows of metallic emerald, turquoise, and ruby-red scales framing a neon sapphire-blue eye, and its ability to produce audible clicking or croaking sounds using specialized pectoral fin muscles during courtship and territorial displays.
Care
Keep in a small group of 3–6 individuals in a warm, heavily planted aquarium starting at 30 liters (24–28 °C, pH 6.0–7.0, GH 4–10) with gentle flow and floating plants (Phyllanthus fluitans, Salvinia) to diffuse bright lighting. Because they breathe atmospheric air via their labyrinth organ, maintain warm humid air above the water surface. Because labyrinth fish are sensitive to chill and parasites, keep our 48-Hour Fish Dropsy Guide and Velvet Disease (Oodinium) Cure bookmarked.
Feeding
Micro-carnivore: relishes live and frozen daphnia, baby brine shrimp, cyclops, blackworms, and mosquito larvae, alongside high-protein slow-sinking nano granules offered near the surface.
Breeding
The male constructs a small bubble nest beneath a broad Cryptocoryne leaf or floating plant roots. During courtship, both fish emit rapid croaking clicks before the male gathers 40–100 eggs into the nest and guards the fry until free-swimming.

Caution
FAQ
- Can you really hear Sparkling Gouramis croak outside the aquarium?
- Yes! By snapping specialized pectoral fin tendons against their swim bladder, Trichopsis pumila produces a rapid clicking sound clearly audible within a quiet room.
- Can multiple male Sparkling Gouramis live together?
- Unlike Bettas, Sparkling Gouramis are peaceful enough to live in mixed-sex groups of 4–6 in a heavily planted 30–40 L tank, settling rivalries with harmless croaking displays.
