A cavitation bubble allows them to shoot a “bullet” of water at prey or potential predators. The target gets stunned, and it’s even possible to see a brief flash of light when the bubble collapses.

Pistol shrimp are one of the most popular snapping shrimp species, and they form a symbiotic relationship with gobies.

If you want to include a pistol shrimp, consider purchasing it WITH its paired goby. They need an established relationship to settle in. Pet stores often sell this combination, letting you introduce the two into your tank at one time.
