Overview

October 16, 2026 · Suggest an edit

The golden whiptail is an elegant species from Colombia's Magdalena basin and a close relative of the royal whiptail. In older sources it appears under the name Sturisoma aureum. Its most distinctive feature is the very long filament-like extensions at the tips of the dorsal and tail fins.

Although scientific sources give a standard length of 20 cm, aquarists report that most fish stay at around 15 cm. Thanks to its slender build it produces far less waste than bulky plecos of the same length.

Tank Setup

October 16, 2026 · Suggest an edit
  • At least 200 liters and 120 cm length for a pair.
  • A strong filter, noticeable flow and good aeration.
  • Roots, flat stones and plants; 24–26°C.

Diet

October 16, 2026 · Suggest an edit

Mainly herbivorous. Make spirulina and vegetable tablets, blanched zucchini and spinach the staple; brine shrimp or small bloodworms can be added a few times a week.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

Extremely peaceful; it stays stuck to the glass or a root for long periods. It does not harm other fish or plants.

Good companions: Tetras, rasboras, rainbowfish, corydoras, shrimp.

Avoid: Fin-nipping fish, aggressive cichlids that claim the bottom, large and greedy plecos.
