紅霓虹藍眼
The Red Neon Blue-eye is an ultra-tiny blue-eye fish known only from wetlands around Timika in Indonesia's Papua province, with adults reaching just about 1.9 cm in standard length. Mature males turn a striking red-orange with a glowing neon-blue stripe along the flank during their breeding display. Males also develop a thread-like elongated second dorsal spine and first pelvic fin ray that trail delicately as they swim. Lively and unafraid when kept in a group, this species is nonetheless small and sensitive to water changes, so it's best suited to intermediate keepers who can maintain steady conditions.

關於紅霓虹藍眼
The Red Neon Blue-eye is a tiny blue-eye fish found only in wetlands of Indonesia's Papua province. Males display a striking red-orange and neon-blue breeding color; here's what intermediate keepers should know.
迎接紅霓虹藍眼前需要了解的7件事
1Thrives in Nano Tanks
Adults reach only about 1.9 cm in standard length, so this species suits even small nano tanks. Because of its tiny size, choose tankmates carefully and keep the tank well covered, since it can easily be startled by larger fish or slip through gaps.
2Vivid Color in Males Only
The striking red-orange body with a glowing neon-blue stripe is a male trait. Females are far more subdued in color, so the two sexes look quite different at a glance.
3Males Grow Filament Fins
Males develop an elongated second dorsal spine and a thread-like first pelvic fin ray. Watching these delicate filaments trail as the fish swims is one of the joys of keeping this species.
4From a Single Wetland Range
This species is known only from wetlands around Timika in Indonesia's Papua province. Having adapted to that specific environment, it tends to be sensitive to sudden changes in water quality or temperature.
5Best for Intermediate Keepers
This species is rated as suitable for intermediate keepers. Its small size makes it sensitive to environmental swings, so consistently maintaining stable water quality and temperature is important.
6Best Kept in a Group
Keeping several individuals together lets you see their natural, settled schooling behavior and the color displays males show off to one another. Consider bringing home a small group rather than a single fish.
7Acclimate Slowly at Arrival
Because this fish is small and delicate, avoid sudden shifts in temperature or water chemistry when introducing it, and give it a slow, gradual acclimation to help prevent stress. Keep a close eye on it during the first days after arrival.
