Frequently Asked Questions

How many Gold Laser Corydoras should be kept together?
Maintain a minimum group of 6 to 8 individuals in a tank of at least 20 gallons (75 liters) with a footprint of 30x12 inches (75x30 cm). Gold laser corydoras (Corydoras aeneus 'Gold Laser') are highly social bottom dwellers that display a striking metallic gold stripe best on dark sand substrates. Groups under 5 cause chronic hiding and stress. A school of 10+ exhibits natural shoaling and active bottom foraging. Provide fine sand substrate (depth 1-2 inches) to protect barbels. Keep one species per group; mixing cory species reduces social bonding.
What are the exact water parameters for Gold Laser Corydoras?
Target pH 6.0 - 7.5, General Hardness 2 - 12 dGH, Carbonate Hardness 2 - 8 dKH, Total Dissolved Solids 80 - 250 ppm, Electrical Conductivity 160 - 500 μS/cm, and temperature 72°F - 78°F (22°C - 26°C). They require clean, well-oxygenated bottom water with regular sand maintenance. Maintain nitrates below 15 ppm with weekly 25% water changes. Use a sponge filter or gentle canister; strong currents stress them. Fine sand (0.5-1 mm grain) is mandatory; gravel damages barbels. Add driftwood and leaf litter. Avoid salt (tolerance <2 ppt).
What is the dietary and medication protocol for Gold Laser Corydoras?
They are omnivores requiring 35% protein, 10% fat, 55% plant matter. Feed premium sinking pellets (Hikari Sinking Wafers), shrimp wafers, live blackworms, frozen bloodworms, and daphnia daily. Offer blanched zucchini and spirulina tabs weekly. Ensure food reaches the bottom; surface leftovers cause starvation. Medication alert: Extremely sensitive to copper (0.1 mg/L lethal) and formalin. Scaleless; use malachite green at quarter dose (0.025 mg/L). Praziquantel is safe. Avoid salt (tolerance <2 ppt). Quarantine with metronidazole at half-strength.
How to breed Gold Laser Corydoras with environmental triggers?
Condition a group of 6-8 with live blackworms and bloodworms for 2 weeks. Simulate dry season: Lower water level to 5 inches (12 cm) for 7 days. Trigger breeding: Perform 50% water change with cool (68°F/20°C) RO water (pH 6.5, 2 dGH) over 2 hours, mimicking heavy rain. Increase aeration. The female adopts a 'T-position' and lays 100-200 adhesive eggs on glass, plants, or mops. Remove parents after spawning. Eggs hatch in 3-5 days at 75°F (24°C). Fry feed on infusoria for 3 days, then microworms, then baby brine shrimp after day 7.
