迎接皇帝灯鱼前需要了解的7件事

1. 1Keep them in a group

   Emperor Tetras have a strong schooling instinct and tend to look nervous or dull when kept alone or in very small numbers. Keeping a proper group together lets them display their natural schooling behavior and coloring.

2. 2Telling males from females

   Males have blue irises and, as they mature, tend to grow longer central rays on the tail fin. Females have greenish irises and a somewhat rounder body shape, making the sexes easier to distinguish once they reach adulthood.

3. 3Peaceful and community-friendly

   They are peaceful fish that rarely chase tankmates, making them a good fit for community tanks with other calm species of similar size. Housing them with aggressive fish can lead to their long fins being nipped, so tankmate choice matters.

4. 4Avoid sudden water changes

   As a small South American characin, this species tends to be sensitive to sudden shifts in water parameters. Acclimate them carefully when introducing them to a new tank, and favor small, frequent water changes over large infrequent ones.

5. 5Fins can be easily damaged

   The long dorsal, anal, and tail fins are beautiful but can be damaged by strong water flow, sharp decorations, or aggressive tankmates. It helps to consider flow strength and layout when setting up their tank.

6. 6Provide places to retreat

   Adding driftwood and plants to create shaded spots helps them feel secure enough to show their natural colors and schooling behavior. They tend to prefer moderate lighting over very bright setups.

7. 7Prepared food works well

   They are omnivorous and do well on small pellet or flake food as a staple diet. Since their mouths are small, check that the food size is appropriate and feed small amounts several times a day to avoid leftovers.
