Glowlight Danio

Care

The Glowlight Danio is an attractive little fish which is peaceful in nature and is suitable for cooler-water community aquaria which incorporate a good flow rate. This is a shoaling species which must be maintained in groups of six or more. Dense plant cover (including floating plants) is very much appreciated, along with an open-swimming area in the centre of the tank. Glowlight Danios will do well with other peaceful fish of a similar size, but boisterous tankmates will cause these fish to become reclusive. As with other Danio species, long-finned tankmates may prove too much of a temptation and are not recommended. Discovered almost 80 years ago, it is somewhat surprising that the vibrant Glowlight Danio did not appear in our shops earlier than it did.

Feeding

Flake, micropellets, and small frozen foods such as daphnia, mosquito larvae, baby brineshrimp etc.

Breeding

Fairly difficult. A separate softwater breeding aquarium (of at least 30" in length) should be set up with a substrate of marbles, and decorated with plenty of fine-leaved plants/large clumps of Java moss. Spawning is a very active affair and can last quite some time; hence the tank should not be too small. Your conditioned trio or group (2:1 male:female ratio) should be acclimatised to this aquarium, and the coverslides closed tightly shut to prevent them from jumping out during their courtship ritual. The temperature should be set to 25 °C. The eggs will be scattered over the plants and marbles, and once spawning has ceased, the hungry parent fish should be acclimatised back to the main aquarium in order to prevent predation on the eggs. After approximately 72 hours the eggs will hatch into wrigglers, and these will become free-swimming 4 or 5 days later. At this point the delicate fry can be offered infusoria, moving onto larger foodstuffs as they grow.
