Neon blue-eye Rainbowfish can be bred and raised in both brackish and fresh water. Keeping and breeding can be done under the following water conditions: temperature 21-27°C, pH 7.1-8.5, conductivity 227-560 µS/cm, TDS 230-290 ppm and hardness 130-140 ppm. Most spawning activity was recorded at a temperature range of 25-27°C; pH 7.7 – 8.5 and conductivity 265-560 µS/cm. Many hobbyists, however, report that the Neon blue-eye will live longer, breed more freely, and produce more offspring if maintained in brackish water. 25-50% seawater made up with one of the commercially available salt mixes should suit them fine.
