Quick Overview of the Powder Blue Dwarf Gourami
The Powder Blue Dwarf Gourami (Trichogaster lalius var. “Powder Blue”, formerly Colisa lalia), also known as the Coral Blue or Neon Blue Dwarf Gourami, is a selectively bred color variant of the classic South Asian dwarf gourami. Reaching a compact adult size of 2.5 to 3 inches (6 to 7.5 cm), this variety is celebrated for replacing the traditional alternating red-and-turquoise vertical stripes with an almost solid, glowing metallic cyan-to-powder-blue coat across its flanks.
As shown above, mature specimens exhibit a subtle orange sheen along the posterior fin fringes and dorsal crest, creating a warm, contrasting halo around their cool pastel chassis. Like all labyrinth fish, they possess modified pelvic fins that act as delicate sensory “whiskers” to touch and examine their surroundings, alongside a specialized labyrinth organ allowing them to breathe atmospheric air directly from the water’s surface.

Local Care Tips for Bacolod Aquarists
Bacolod Tap Water Synergy, Labyrinth Health & Calm Flow: Powder Blue Dwarf Gouramis adapt seamlessly to Bacolod’s typical neutral-to-slightly-hard tap water (pH 6.8–7.6) when conditioned with a high-grade dechlorinator during weekly maintenance. Because they originate from slow-moving streams, vegetated rice fields, and marshes, gentle water flow is essential. Avoid strong wavemakers; instead, utilize a sponge filter or a baffled hang-on-back filter to keep surface agitation soft. A tight-fitting aquarium cover or canopy is mandatory to maintain a warm, humid pocket of air directly above the water line, protecting their labyrinth organ from chill shock while stopping curious surface leaps.
Aquascaping Strategy, Floating Cover & The Epiphyte Rule: These gouramis display their most vivid metallic blue tones when they feel secure under cover. Supply an overhead blanket of floating plants (Salvinia, Red Root Floaters, or Water Lettuce), which males naturally use to construct delicate bubble nests during breeding displays. Frame the midground and hardscape with easy-care epiphytes like Anubias Barteri, Anubias Nano, Java Ferns, or Bucephalandra bound to local driftwood or Seiryu stones—just remember the golden rule: the creeping rhizomes of these epiphytes must remain completely exposed above the substrate to keep them from rotting!
Dietary Specifics & Community Harmony: Dwarf Gouramis are unfussy omnivores that thrive on a diverse diet. Feed high-quality micro-pellets, spirulina flakes, and regular treats of frozen bloodworms, daphnia, and brine shrimp. They are peaceful community residents that pair harmoniously with small schooling tetras (like Cardinal, Costae, or Congo Tetras), Rasboras, Pygmy Corydoras, Otocinclus, and Horned Nerite Snails. While they peacefully coexist with adult Neocaridina/Caridina dwarf shrimp, their inquisitive nature means they will readily snack on unprotected newborn shrimplets, so ensure dense moss beds are available if breeding shrimp.
