The Pencilfish is an easy breed to keep in the home aquarium because its tank requirements are easy to achieve. These fish prefer soft, slightly acidic water with a pH range between 5.5 and 7.0 and a temperature range between 72°F and 82°F. The tank should be decorated with plenty of live plants as well as driftwood and rockwork to provide hiding places. These fish are sensitive to high nitrate levels, so frequent water changes are necessary. It is also important to note that these fish are jumpers, so keep the tank covered.

Breeding Info

In order to increase your chances for success, it is best to remove Pencilfish from the community tank for breeding. These fish are egg layers and they tend to scatter their eggs over plants. These fish will eat their own eggs and fry, so remove them from the tank after spawning.

There are currently 19 species of Pencilfish which have been identified but not all of them are common in the aquarium trade. The most popular species of Pencilfish for the home aquarium include the following: Golden Pencilfishes, Two-Stripe Pencilfishes, Brown Pencilfishes, Dwarf Pencilfishes, Shining Pencilfishes, Three-Stripe Pencilfishes, and One-Line Pencilfishes.
