海水蝦

關於海水蝦

Marine shrimp are crustaceans found across tropical and subtropical seas worldwide, and they have been a beloved part of the reef-keeping hobby for decades. The Skunk Cleaner Shrimp, with its striking red-and-white coloration, is perhaps the most iconic — it operates cleaning stations where fish line up to have parasites and dead tissue removed from their gills and skin. The Camel Shrimp, named for its distinctive arched body, is another popular choice, known for its quirky swimming style and association with bubble-tip anemones. Both species thrive in stable, well-maintained reef tanks where salinity, temperature, and trace elements are kept consistent. Watching a shrimp deftly manipulate food with its chelipeds, or observing the remarkable shedding of an exoskeleton during a molt, offers endless fascination. The opportunity to witness genuine symbiotic behavior between shrimp and fish — right inside your own aquarium — is one of the most rewarding aspects of keeping marine shrimp.

迎接海水蝦前需要了解的7件事

1. 1Highly Sensitive to Water Changes

   Marine shrimp are far more sensitive to water quality than most fish, requiring ammonia and nitrite levels at near zero. Even trace amounts of copper-based medications—common in ich treatments—can be lethal to them. Always use invertebrate-safe treatments and perform water changes slowly using the drip method.

2. 2Drip Acclimation Is Essential

   Newly acquired shrimp are at high risk of osmotic shock from sudden changes in temperature, salinity, or pH. Drip acclimation over one to two hours is the standard approach. Taking extra time when salinity levels differ significantly between your tank and the transport water greatly improves survival rates.

3. 3Molting Is a Vulnerable Period

   Shrimp molt periodically to grow, and freshly molted individuals are soft-shelled and vulnerable to aggression from tankmates. You can leave the shed exoskeleton in the tank as a calcium source, or crush and offer it back. Supplementing iodine and calcium supports healthy molting cycles.

4. 4Careful Tankmate Selection Required

   Fish such as wrasses, triggerfish, and blennies may prey on shrimp. For cleaner shrimp to function properly, pair them with peaceful fish that recognize cleaning stations. Even among shrimp, some species compete territorially, so research compatibility before adding multiple species to the same tank.

5. 5Maintain Proper Salinity and Specific Gravity

   A specific gravity of 1.023–1.026 (approximately 33–35 ppt salinity) suits most marine shrimp species. Daily top-off with fresh water—or an automatic top-off (ATO) unit—prevents salinity from rising as water evaporates. A refractometer gives more accurate readings than a swing-arm hydrometer.

6. 6Provide Rock Structures for Shelter

   Marine shrimp naturally seek crevices and cave-like structures to hide during molting and resting. Live rock aquascaping provides both shelter and a surface for beneficial bacteria to colonize. Ample hiding spots reduce stress, which contributes to overall health and longevity.

7. 7Expected Setup and Ongoing Costs

   Keeping marine shrimp requires saltwater-specific equipment such as a protein skimmer, refractometer, and live rock, making initial costs higher than freshwater setups. Common species like Skunk Cleaner Shrimp typically range from around ¥1,000 to ¥3,000 per individual. Budget for ongoing costs such as synthetic sea salt mix, as regular top-offs and partial water changes consume it steadily.

海水蝦的常見問題

Q.Can marine shrimp be kept with fish?

A.Yes, with peaceful small fish, but avoid species like large wrasses or predatory fish that may eat the shrimp. Always research each fish's feeding behavior before adding it to a shrimp tank.

Q.Should I remove the molted shell from the tank?

A.Generally, leave it in the tank — shrimp often eat their own molt to reclaim calcium. If it remains untouched after a few days, it is safe to remove it manually.

Q.How long do marine shrimp live?
