Breeding

How to breed the Glowlight tetra?

Reproduction is possible but quite delicate. Place a male and a female (but also possible in a group) in a laying trough (20 litres / 4 Imp Gal / 5 US Gal) with a protective grid and fine-leaved plants such as Java moss. The tank is dimly lit. A peat filtration will be a plus as well as the use of osmosis water. Temperature 24°C (75°F) and KH at 2°. Beforehand, separate the sexes and prepare for spawning by feeding the parents plenty of live prey. Introduce the parents in the evening, spawning should take place the next day. As soon as the eggs appear, remove the adults. Incubation lasts 19 hours. The fry are very sensitive to nitrates.

Feed the fry: infusers, artemia and cyclops nauplia.

A little shy by nature, he likes the profusion of plants and hiding places. On the other hand, in a not very furnished decoration, this fish will tend to tarnish.

The best is to keep it in an aquarium in an Amazonian biotope. To do this, opt for peat filtration.

On the decoration side, make a beautiful arrangement of twisted roots or driftwood. For a natural effect, the substrate will be river sand on which you will place dried leaves (beech or oak). These leaves will tint the water with a colour close to that of tea. Replace these leaves before they rot.

On the plantation side, the only rule is that it should be dense and lush, but still leave space for swimming.

Finally, dim the lighting with floating plants.

In such a planter, the Glowlight tetra will show you its most beautiful colours!

He has a heart condition and is very vulnerable to white spot disease. Avoid stress and plan for a very gentle and least stressful acclimatization to avoid the onset of illness. For the same reasons, place the tray in a quiet place.

Apart from that, this species remains a good choice for beginners because it is hardy and inexpensive.
