刚果霓虹鱼
The Congo Tetra is a strikingly colorful characin from Central Africa, its scales flashing blue, gold, and orange under the right light. Males grow long, flowing extensions on their dorsal and tail fins, making a shoal of Congo Tetras one of the most eye-catching sights in a community tank. They're generally peaceful and get along well with other calm tankmates, though their size and delicate fins make them a bit sensitive to sudden changes in water quality. Considered a fish for hobbyists with some experience, they do best with keepers already comfortable maintaining stable water conditions. Congo Tetras typically live 3 to 5 years and reach an adult size of about 6 to 8.5 cm.

迎接刚果霓虹鱼前需要了解的7件事
1Best Kept in a Shoal
Congo Tetras are schooling fish that show their most natural, relaxed behavior and best coloring when kept in a group rather than alone. A small or single fish tends to hide, so plan for a shoal sized to match your tank.
2Sensitive to Water Changes
Sudden shifts in water quality can dull their fin condition and coloring or cause stress. It's best to introduce them only after a tank has fully cycled, and to keep filtration and water changes on a consistent schedule.
3Males Grow Flowing Fins
Mature males develop elegant, elongated dorsal and tail fins that make a shoal especially striking. Females stay comparatively plain and rounder-bodied, so the sexes become easy to tell apart as they mature.
4Choose Fin-Safe Tankmates
Their long fins can be damaged by fish with a tendency to nip. Peaceful species that share a similar swimming level make calmer, safer tankmates.
5Subdued Lighting Suits Them
Under overly bright light, Congo Tetras can look washed out and skittish. Slightly dimmed lighting paired with a darker substrate brings out their blue and gold shimmer.
6Adults Reach 6-8.5 cm
Fully grown, Congo Tetras reach about 6 to 8.5 cm, so a shoal needs enough tank length to swim comfortably. It's worth picturing this adult size and confirming your tank has the room before bringing them home.
7Acclimate Slowly After Arrival
This species can be sensitive to the stress of transport and a new environment, so a slow, careful acclimation helps them settle in. Since they're considered suited to hobbyists with some experience, brushing up on basic water quality management beforehand is a good idea.
