Green Laser Corydoras - Corydoras sp. (CW009) : Complete Fish Profile & Care Guide

Table of contents


Green Laser Corydoras are peaceful and sociable and make a great addition to the community tank. These Corys would be best housed with small to medium-sized tankmates such as Rasboras, smaller Barbs, Danios and Tetras. However, placing these Corys in a species-only tank would be best if you specifically want to breed them. These Corys enjoy the company of their own kind, so they should be kept in groups of six or more individuals. Keeping them in more significant numbers will allow you to witness their fascinating behaviours. A moderate amount of current in the tank is required for Green Laser Corys. Keeping them healthy and happy requires a good filtration system and regular water changes. To protect the delicate sensory barbels, a soft sand substrate is recommended, as well as some shady planting areas. Corydoras can breathe air intestinally, so a small gap should be left between the surface of the water and the cover slides so the fish can come up to the surface and take air in. It may do this numerous times per day. Future scientific evaluations may prove Green Laser Corys are a separate species from Corydoras aeneus, but it could be one of many natural colour variants. A Green Lazer Cory has a greenish-olive body covered with a luminescent lime-green sheen. A bright, neon green line runs from their eye, along their back, and ends at the caudal peduncle.

Sexual Dimorphism

It can be somewhat challenging to differentiate between a male and female Green Laser Corydoras as they look very similar. However, the females are usually slightly larger than males and appear much wider when viewed from above. Males, on the other hand, are smaller, their pelvic fins are more pointed, and they have longer pectoral fins than females.

Natural habitat

Green Laser Corydoras are native to the Upper Amazon, Marañón, Ucayali and Middle Ucayali Rivers in Peru in Western South America. These Corys inhabit calm, shallow running waters such as streams, rivers, creeks and flooded forest areas with a soft substrate.

How to breed the Green Laser Corydoras

For hatching and growing the fry, a separate breeding tank is recommended. The tank should be heavily planted, spawning mops would also work, and the substrate should be sand or smooth gravel. A bare-bottom tank is also fitting. When breeding Corydoras, the water should be somewhat acidic and soft, and more males should be present than females. Therefore, two males for every female is advised. Ideally, you should condition the breeding group on live and frozen foods, as this will encourage spawning. When the females are full of eggs, you should perform a profound water change with colder water and increase the tank's flow and oxygenation. Replicate this daily until the Corydoras spawn. A heightened activity level usually precedes spawning, and the males continue to pursue females. During the process of procuring a male, a female puts her head against the midsection of the male, the male clasps the barbels of the female with his pectoral fins, and the female forms a basket with her pelvic fins that contains up to four eggs. Once the eggs have been fertilised, the female will find the right spot to attach her sticky eggs. This process will continue until she has laid all her eggs. The parents will not care for nor protect the eggs once they have been laid and will more than likely eat them, so you must separate them if the fry is to survive. The eggs will usually hatch three to five days later, and you should then feed them freshly hatched micro-worms, rotifers or brine shrimp.

Diet & feeding

In the home aquarium, the Green Laser Corydoras will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements. Additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide other benefits to your fish's health and well-being but is not a must for this fish. It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages. This fish is an omnivore in the wild, consuming some vegetable matter. Although most modern fish foods consider this and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.
