Spanner Barb
Barbodes lateristriga
Animalia›Chordata›Actinopterygii›Cypriniformes›Cyprinidae
📍 Malay Peninsula, Sumatra & Borneo
Distinctive barb with two vertical black bars and a horizontal stripe forming a T-shape or spanner wrench pattern. Grows to a respectful size. Peaceful and adaptable; great for a large community tank.
Care Guide
Diet
Spanner Barbs are omnivores that thrive on a varied diet of high-quality flake foods, small pellets, and regular supplements of frozen foods like brine shrimp, daphnia, and bloodworms. Feed once daily in amounts they can consume within 2-3 minutes. Occasional vegetable matter such as blanched spinach or algae wafers supports digestive health.
Behavior
Spanner Barbs are peaceful, active schooling fish that prefer to swim in groups of at least 5 individuals, displaying more natural behavior and reduced stress when kept together. They occupy the mid-water column and are generally non-aggressive toward other community fish, though they may occasionally nip at slow-moving or long-finned species. They are moderately active during daylight hours and appreciate open swimming space with some planted areas for refuge.
Breeding
Breeding Spanner Barbs in captivity is possible but requires specific conditions including slightly acidic water (pH 6.0-6.5), temperatures around 26-27°C, and dense vegetation or spawning mops for egg adhesion. Condition breeding pairs with live foods for 1-2 weeks before spawning, then separate them after eggs are laid as parents may consume fry. Fry are small and require infusoria or liquid fry food initially before graduating to micro pellets.
Tank Mates
Similar size, peaceful temperament, and identical water parameter requirements make them ideal community companions
Small, peaceful schooling fish that occupy similar water zones and share compatible temperature and pH ranges
Peaceful mid-water dweller with compatible temperature needs; monitor for any territorial behavior
Nocturnal algae eater that occupies different ecological niche; prefers slightly cooler temps but adaptable
Excellent algae control and peaceful; barbs may occasionally chase but rarely cause serious harm
Common Diseases
Ich (Ichthyophthirius multifiliis)
White spots resembling salt grains on body and fins, rapid gill movement, lethargy, rubbing against objects
Raise temperature gradually to 28-29°C, perform daily 25% water changes, use aquarium salt (1 teaspoon per 5 gallons) or commercial ich treatment; continue for 10-14 days
Fin Rot
Fraying or deterioration of fin edges, discoloration at fin bases, fins becoming shorter over time
Improve water quality with frequent partial water changes, maintain optimal temperature (24-26°C), use antibacterial medication if severe; remove any sharp tank decorations
Bacterial Infection
Redness or inflammation on body, open sores, cloudy eyes, loss of appetite, lethargy
Perform 30% water change immediately, maintain pristine water conditions, use broad-spectrum antibiotic treatment; isolate severely affected fish if possible
Parasitic Infection (Anchor Worms/Lice)
Visible worm-like parasites or small crustaceans on body, excessive scratching, localized inflammation
Use anti-parasitic medication following label directions, perform frequent water changes, quarantine affected fish; manually remove visible parasites with tweezers if possible
