Overview

October 16, 2026 · Suggest an edit

The Pinocchio whiptail gets its name from its long, pointed snout. With its sand-colored, flat body it becomes almost invisible on sandy bottoms in the wild. It spends most of its time motionless, searching for small creatures in the sand.

It has an interesting way of breeding: the male carries the egg cluster laid by the female between the folds of his lips and guards it throughout incubation. During the breeding season the male's lips enlarge noticeably. Adults grow to 13–14 cm.

Tank Setup

October 16, 2026 · Suggest an edit
  • 80 liters for a small group, with a large footprint.
  • A fine, soft sand substrate is essential; sharp gravel damages its mouth.
  • 25–27°C, clean water and gentle flow.

Diet

October 16, 2026 · Suggest an edit

It feeds on small invertebrates by sifting the sand. Frozen bloodworms, brine shrimp, daphnia and sinking granules should be given; vegetable tablets are also accepted. It may fall behind in the competition for food with fast-eating fish.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

Extremely calm and peaceful; it lies motionless on the sand for hours.

Good companions: Small tetras, rasboras, otocinclus, dwarf cichlids, calm groups of corydoras.

Avoid: Cichlids that claim the bottom, greedy and fast bottom dwellers, large plecos.
