Green Neon Tetra (Paracheirodon simulans)

The Green Neon Tetra (Paracheirodon simulans) is the smaller, more intensely blue-green cousin of the classic neon, with an electric stripe that runs the full length of the body. It tops out around an inch, which makes it one of the best schooling fish for nano and planted tanks. Peaceful and best kept in soft water, it rewards a stable tank with tight, glowing schools.

Care Guide

• Group size: 10 or more. Larger schools show better color and behavior.
• Tank size: 10 gallons or larger.
• Water parameters: 75 to 82°F, pH 4.0 to 6.5, soft water (1 to 8 dGH). Stability matters more than hitting an exact number.
• Feeding: micropredator. Fine crumbles, Hikari Micro Pellets or Xtreme Nano pellets, plus baby brine shrimp or daphnia a few times a week.
• Aquascape: plants, driftwood, subdued light and a few catappa leaves for soft, tea-stained water bring out the best color.

A little. It prefers soft, acidic, stable water and does not like big swings. Buy a group of 10 or more.
