The zebra mantis shrimp is the largest stomatopod in the world, a pale, boldly dark-banded 'spearer' that lives in a deep vertical burrow and ambushes passing fish and shrimp with spine-lined, harpoon-like raptorial claws. Long-lived, secretive and best kept in a tall, deep-substrate species tank, it is an advanced specimen for keepers fascinated by its sit-and-wait predation rather than a display animal that is out in the open.

Part of the Mantis Shrimp
Stomatopods — not true shrimp — are powerful, intelligent marine crustaceans armed with raptorial appendages that either club (smashers) or spear (spearers) their prey, plus some of the most advanced eyes in the animal kingdom. Often arriving as hitchhikers and feared as tank pests that can crack glass and crush snails, they are also kept on purpose as fascinating specimens in dedicated species ta

Larva
Most marine invertebrates hatch into microscopic planktonic larvae (such as the zoea of crustaceans or the bipinnaria/veliger of echinoderms and mollusks) that drift and feed in the water column. The larva looks nothing like the adult and undergoes major reorganization.

Juvenile
After settling out of the plankton, the juvenile takes on a recognizable miniature of the adult body plan — a tiny shell, a small star, or a translucent shrimp. Crustaceans grow by molting, shedding the exoskeleton to enlarge.

Adult
Adults reach full size and reproductive maturity with the species' mature shell, shape, or coloration. Many continue to molt or grow throughout life, and some show sex differences in size or claw/appendage shape.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Natural
Natural form
The wild-type animal: a large, pale tan-to-cream body crossed by bold dark transverse 'zebra' bands, with mobile stalked eyes and long, spine-lined spearing claws. All specimens are wild-caught; there are no bred color strains.
Habitat & enclosure
Keep a single zebra mantis (or, for this socially monogamous species, a confirmed male-female pair) in a dedicated species tank of at least 40-55 gallons (150-210 L) with a very deep sand/mud-and-rubble bed — ideally 20-30 cm (8-12 in) or more — so it can dig the long vertical burrow it spends most of its life in. Maintain stable tropical reef parameters: temperature 72-80F (22-27C), pH 8.1-8.4, salinity SG 1.024-1.026, alkalinity 8-11 dKH and low nitrate with no ammonia or nitrite.
It ranges widely across the Indo-Pacific from East Africa to the Galapagos and Hawaiian Islands, in sandy lagoon and reef-flat bottoms. The depth and stability of the burrow substrate matters far more to it than rockwork or lighting; provide a tight lid, as a tall tank with deep sand still needs containment.
Substrate
A very deep, stable bed of fine sand mixed with mud and rubble is the single most important requirement, since the animal lives in a long vertical burrow it digs and lines; aim for the deepest practical sand bed (often 20-30 cm or more). Rockwork is secondary and should sit on the tank bottom so the burrow can't undermine it.
Equipment & setup
Standard reef filtration (live rock or live sand biofiltration, protein skimmer, heater, gentle-to-moderate flow) on a strictly copper-free system suffices, with trace iodine maintained for clean molts. The critical 'equipment' is a tall tank with an extra-deep substrate and a tight, secured lid to prevent escape. A red night-viewing light helps observe its nocturnal activity.
Diet
An ambush 'spearer' carnivore that waits at its burrow mouth and impales passing fish and shrimp on its spine-lined dactyls, rather than crushing hard shells like the smashers. Feed meaty foods — pieces of marine fish, whole shrimp, and similar items — offered on feeding tongs near the burrow entrance every couple of days. It is a sit-and-wait feeder, so target-feed it at its burrow rather than expecting it to roam for food.
Behavior & temperament
Reclusive and burrow-bound: it spends most of its time hidden in its tunnel with only its eyes and antennae showing, lunging out to spear prey. It is NOT reef- or community-safe — it will spear and eat fish and shrimp small enough to catch — so it is kept alone (or as a bonded pair) in a dedicated tank with no intended tankmates. Unusually for stomatopods it is socially monogamous with maternal care, and a true pair can share a large burrow system, but unsexed or mismatched individuals should be kept solo. It is far less of a 'glass-cracker' than the smashing peacock mantis, since its spearing claws are not built to club.
Health
Hardy and remarkably long-lived for an invertebrate, but as a crustacean it is sensitive to copper, salinity and temperature swings and to low iodine/trace elements that cause failed molts; never use copper medications and maintain trace iodine. KEEPER SAFETY: the spined raptorial claws can deliver a deep, lacerating stab — never handle it bare-handed, move it only in a rigid container, and keep a secure lid since it can leave the burrow at night. Its main husbandry challenge is providing and maintaining a deep, stable burrow substrate; a too-shallow bed leaves it stressed and exposed. (Educational and safety information only — not medical or veterinary advice.)
Tips, DIY & hacks
Provide the deepest sand bed you can and resist disturbing the burrow once established. Keep it alone unless you have a verified male-female pair, and never with fish or shrimp it could spear. Handle only with a rigid container — never bare hands — and keep the tank tightly covered. Target-feed meaty foods at the burrow mouth with tongs, and be patient: this is a secretive ambush predator, not an out-in-the-open display animal.
