迎接叉尾藍眼前需要了解的7件事

1. 1Intermediate-Level Care

   This species is sensitive to sudden shifts in water quality, so keeping pH and temperature stable takes some basic fishkeeping skill. If you're new to tropical fish, it may help to gain experience with hardier species first.

2. 2Fine for Small Tanks

   Adults reach only about 5cm (males) at most, so a shoal can thrive even in limited space. Because smaller volumes of water fluctuate more easily, make sure your filtration has enough capacity to keep parameters stable.

3. 3Males Display to Rivals

   During the breeding season, males spread their fins wide to show off to rival males — a behavior that's part of the species' appeal. It rarely escalates into serious aggression, but adding hiding spots helps fish settle in comfortably.

4. 4Yellow-Edged Fins

   The yellow trim on the dorsal and anal fins, along with the forked tail, are the easiest features for telling this species apart. How the colors catch the light can vary, so thoughtful lighting can bring out their best appearance.

5. 5Choose Calm Tankmates

   Being small and peaceful, this fish can get stressed by boisterous or larger tankmates. Pair it with similarly sized, calm species and provide plants or decor for cover.

6. 6Cycle the Tank First

   Start your filter running and let water parameters stabilize before bringing fish home. Take your time acclimating new arrivals to avoid sudden changes in water conditions.

7. 7A Range-Restricted Species

   This fish is known to occur only in a limited range of waters in eastern Papua New Guinea. Keeping that natural habitat in mind can guide you toward a calmer, more settled tank environment.
