Yellowline Arrow Crab
(Stenorhynchus seticornis)

Descrição

The Yellowline Arrow Crab (*Stenorhynchus seticornis*) is a unique and fascinating marine invertebrate often sought for its distinctive appearance and cleaning habits in a reef aquarium.

**Appearance & Behavior**: This crab is instantly recognizable by its extremely long, spindly legs—up to three times its body length—and a triangular, arrowhead-shaped body with a pointed rostrum. Its body is typically golden-brown or reddish-brown, often adorned with white, brown, or gold stripes, and features small, often violet-tipped claws. Primarily nocturnal, the Yellowline Arrow Crab spends its day hidden in crevices, rockwork, or among corals, emerging at night to scavenge for food. While their movements can appear graceful, they are also quite territorial, especially towards other crabs of the same species.

**Care Level**: Easy to moderate. These hardy invertebrates are generally simple to care for, making them suitable for beginners in the marine hobby. However, their territorial and opportunistic predatory nature requires careful consideration when selecting tank mates. They are semi-aggressive and should typically be kept singly to avoid conflicts with other crabs. They may pose a risk to small, slow-moving fish, very small crustaceans, or soft corals if underfed.

**Tank Essentials**: A minimum tank size of 115 litres (30 gallons) is recommended to provide ample space and territory, especially if housed alone. They thrive in established marine aquariums with plenty of live rock and crevices for hiding during the day. Maintain water temperatures between 22-26°C (72-78°F) and a pH range of 8.1-8.4.

**Diet**: Yellowline Arrow Crabs are omnivorous scavengers and opportunistic feeders. In the aquarium, they will readily consume various meaty foods such as Mysis shrimp, brine shrimp, chopped prawns, and also help control nuisance bristleworms and detritus.
