Identifying the Gold Laser Corydoras
Gold Laser Corydoras are typically small at 2.5 – 3 inches (6 – 7.5 cm) long when mature with short and stocky bodies despite having a flat underbelly, perfect for laying at the bottom of their tanks.
Color Pattern
Gold Laser Corydoras have a deep brown, gray, or olive-green side with a single bold metallic golden-yellow stripe running from their head to their tail on the bottom sides and top of their body with orangish-yellow tints on the fins.
However, when you flip it over, their underbelly appears white or cream with no stripes. The vibrant horizontal stripe distinguishes the Gold Laser Corydoras and Green Laser Corydoras, which share every other feature.
Unique Traits
Like other Corydoras species, the Gold Laser variant loves spending time near the substrate and has a flat underbelly for a comfortable stay. But it doesn’t stop them from enjoying the company of other tank mates and actively swimming in groups throughout all of their tank.
Creating the Perfect Home: Tank Setup for Gold Laser Corydoras
Are you ready to design the ideal tank conditions for Gold Laser Corydoras to live a healthy and thriving life?
Tank Size
All freshwater fish tank setups should begin with properly sizing the enclosure. You must get a minimum tank size of 20 gallons to house a group of at least six Gold Laser Corydoras with similar-sized species.
Then, design a layout that resembles their natural South American habitat to ensure normal behaviors and stress-free interactions, read on and I’ll show you how.
Substrate & Decor
Fine sand is the best substrate for bottom-dwelling fish. It’s smooth and gentle without risking hurting your pets during feeding. Alternatively, you can use smooth, rounded gravel but never square/sharp-edged types of substrates.
Gold Laser Corydoras fish need hiding spots, shade, and interactive decor. So, add caves and live plants like Amazon Swords, Anubias, Frogbits, and Water Lettuce to create an Amazon Basin aesthetic.
Use only smooth rocks for safety, and add driftwood to release tannins and soften the water.
Water Parameters
Follow these specific parameters to ensure optimal conditions in the tank.
| Temperature | 72 – 79℉ |
| pH | 6.0 – 7.5 |
| Hardness | Soft to moderately hard |
Perform consistent water changes to keep it pristine. Remember without maintaining proper water parameters, the tank’s water quality can degrade, which can cause a wide range of issues from cloudy aquarium water to illness and mass die off.
Flow & Lighting
Because Gold Laser Corydoras are tiny, they need moderate water flow and sponge or single-canister filters to maintain oxygenation.
As nocturnal pets, this species thrives in dim led lighting that mimics their natural habitat, so use floating plants like frogbit to reduce the light’s reflection.

Breeding Gold Laser Corydoras: How to Successfully Raise a Fry
Breeding Gold Laser Corydoras in an aquarium can be a rewarding experience because you’ll get more of this exciting species. So, checkout this section to learn how to breed Gold Laser Corydoras successfully.
Breeding Triggers
Before triggering spawning conditions, follow these freshwater fish breeding tips to ensure your aquarium is up to par.
| Tank Size | 10 – 20 gallons |
| Temperature | 74 – 78℉ |
| pH level | 6.5 – 7.2 |
| Hardness | Soft |
| Diet | High-protein for 2 weeks |
Choose 2:1 female to male ratio for a better chance at successful breeding. When triggering breeding, you must change large water quantities and drop the temperature to the lower recommended value.
Egg Laying
The female Gold Laser Corydoras will hold her eggs in her pelvic fin while the male fertilizes them. After fertilization, females attach their eggs to the tank surfaces, so ensure there’s a large leaf, smooth slate, ceramic, or glass for this purpose.
You must protect the eggs from their parents by removing the adults and keep the environment pristine to prevent fungus growth or contamination.
Fry Care
Within 1 – 3 days, your Gold Laser Corydoras eggs will hatch and fry depending on how the tank gets. Luckily, raising Corydoras fry isn’t as tasking as breeding and egg care.
At this stage, your task is to provide adequate food and monitor the fry for healthy growth. For the first three days, give them infusoria or liquid food. Then, as they develop mouths, you can switch to crushed brine shrimp, microworms, or crushed fry flakes.
Don’t forget to make 20% water changes daily to discourage bacteria growth or infection.
