1. What your Tiger Pistol Shrimp is and where it comes from

The tiger pistol shrimp (Alpheus bellulus) is a species of shrimp belonging to the family Alpheidae, which are commonly known as snapping shrimp. These shrimps typically have a yellowish-white body adorned with brown bands and spots, giving them a tiger-like appearance, and usually reach up to 3 inches in length.

The tiger pistol shrimp is found in the tropical waters of the Indo-West Pacific area, dwelling in sandy, muddy and detrital substrata in shallow waters. What makes this shrimp special is its oversized claw, which it uses to create a powerful snapping sound for hunting and communication.

2. Tank size and substrate

Provide a mature marine aquarium with a sand bed at least 2–3 inches deep. The minimum tank size is 20 gallons. However, some sources recommend fine to medium sand substrate 2–3 inches deep minimum for burrow construction.

A substrate like sand or fine gravel is preferable to allow the shrimp to dig and create burrows. Tiger Snapping Shrimp thrive in environments with sand, rock caves, and dim light. The shrimp's burrowing is not just for hiding—it's essential behavior, and without the right substrate, the shrimp will become stressed.

Include small pieces of rubble rock and live rock to stabilize burrow structures, and ensure open sand areas for extensive tunnel systems.

3. Tank mates and temperament

Tiger Pistol Shrimp are peaceful toward most fish and peaceful toward other corals, but territorial around their burrow. Tiger Pistol Shrimp ignore most fish and corals, but will defend their burrow from other bottom-dwelling shrimp and crabs. Keep only one shrimp per burrow unless you have a known mated pair.

One of the most interesting aspects of this shrimp is its potential partnership with a goby. Because these shrimp have poor eyesight, the goby acts as a lookout for predators while the shrimp provides a home for the goby; both also benefit in sharing food resources. If you want to keep a pair, buy them already bonded rather than hoping two will pair up.

Invertebrates are highly sensitive to copper, and copper-treated water or medications should never be added to an aquarium that houses them.

4. Feeding your pistol shrimp

Typically, pistol shrimp primarily rely on scavenging leftover food and detritus in a well-established aquarium, making supplemental feeding usually unnecessary; however, in certain circumstances, targeted feeding might be beneficial to ensure optimal health and growth.

If you do feed, they will forage on the substrate for meaty foods, such as frozen brine shrimp or mysis shrimp, and various pellet foods. Snapping Shrimp will accept any meaty freeze-dried and frozen foods and bottom feeder tablets.

Signs of underfeeding include lethargy, decreased digging activity, and a lack of scavenging behavior. If you observe these signs, consider supplementing their diet. Deliver food right at the burrow mouth for a burrow-bound shrimp because food isn't always visibly disappearing.

5. Water parameters and stability

Maintaining stable water parameters is a component to the success of keeping this invertebrate; Tiger pistol shrimp are intolerable of high nitrates. Regular water changes are necessary to replenish iodine that is important for the proper molting of Tiger pistol shrimp.

Parameter	Range
Temperature	75–80°F
Salinity (Specific Gravity)	1.024–1.026
pH	8.1–8.4
Alkalinity	8–12 dKH
Calcium	420-440 ppm
Magnesium	1260-1350 ppm
Nitrate	Below 10 ppm
Phosphate	Below 0.10 ppm

The Pistol Shrimp need a correct level of iodine in the water to promote proper molting.

6. How to acclimate your pistol shrimp safely

Gather before you start

Shrimp drip line or airline tubing
Acclimation bucket (1–2 gallon)
Airline valve (to control drip rate)
Container to hold shrimp shipping water
Small fine-mesh net

1. Float the sealed shipping bag in your tank for 15 minutes to let the temperature equalize slowly.

2. Open the bag and place it in a bucket. Let the shrimp stay in its shipping water for now.

3. Set up a drip line from your tank into the bucket at a rate of about 2–4 drops per minute. Drip acclimate slowly, since shrimp are sensitive to sudden changes in salinity and pH.

4. Drip for 45 to 60 minutes so the shrimp gradually adjusts to your tank's water chemistry.

5. Use a net to gently catch the shrimp and move it to the tank. Do not pour the shipping water into your tank.

Molting is natural; shed exoskeletons can look like a dead shrimp. It's incredibly common for new (and even established) pistol shrimp to "disappear" for days or even weeks. Unless you detect signs of death (such as a strong smell or decaying body), assume it's just being reclusive.

7. Signs of good health

What you notice	What to check next
Shrimp is active and digging burrows	Normal; this is healthy behavior
Vibrant coloration and constant digging	Your shrimp is thriving
Shrimp becomes more reclusive, refuses food, or appears duller in color	A molt may be coming; maintain stable water and wait
Lethargy, decreased digging activity, and lack of scavenging behavior	Consider supplemental feeding
Shrimp has lost a claw or other appendage	Check for stress, aggressive tank mates, or a difficult molt; ensure water is stable
Loud popping or snapping sounds	Normal communication and hunting; no action needed
