Breeding
The Glowlight Tetra are egg layers. When they spawn they lock fins, then while clasped they perform a type of roll-over process in the vegetation. Thus the female releases about a dozen eggs at time and the male fertilizes them.
The tank should have dim or no lighting and a water temperature from (26-28°C). Peat filtered water makes for the best results. After conditioning a pair on live foods for a few weeks, introduce the pair into the breeding tank during the evening. The pair should spawn within two or three days. If the pair does not spawn within three days, try the process over again. 120-150 eggs are dropped in plants and on the bottom.
- The fry hatch in 20 to 25 hours.
- Free swimming in 5-6 days
- Spawning cycle 6 to 7 days.
After about 15 days, the young develop the characteristic orange stripe.
