Responsible care profile
The retailer recommends meaty foods and sinking tablets and notes possible predation on tiny shrimp. MLL precautions: stabilise rockwork before excavation, ensure food reaches the burrow, and verify a specific partner rather than promising universal goby compatibility. Numerical temperature, salinity, pH, enclosure and stocking limits remain unverified in this review. Published culture conditions and retailer recommendations are not proven tolerance limits.
The structured record includes multiple references and at least one dedicated aquarium-care source.

Water
Species-matched aquarium source recommendation — https://www.liveaquaria.com/products/snapping-shrimp-red-banded · The operator recommends22.2–25.6°C, specific gravity1.023–1.025 and pH8.1–8.4. Provide sand or mixed burrowing substrate beside stable rockwork that cannot fall when excavated; match acclimation to the supplier's water. Evidence limit: The source gives no minimum permanent tank volume, and its water values are planning recommendations rather than measured tolerance limits.

Numerical temperature, salinity, pH, enclosure and stocking limits remain unverified in this review. Published culture conditions and retailer recommendations are not proven tolerance limits.
Published profile content is not a claim that all captive-care evidence gaps have been resolved.
Batch evidence finding: The association source links Alpheus randalli with Stonogobiops nematodes. Sharing a burrow does not mean the goby provides a nutritionally complete ration or that every introduced pair will accept one another.
Batch monitoring plan: Record shrimp feeding independently of the goby and inspect burrow stability; do not replace a shrimp nutrition plan with the association alone.
2026-10-03: targeted primary-source search and retrieval review. Partial evidence remains limited to the named species, stock, life stage and study scope; remaining questions were not certified as complete.
2026-10-03 scientific review: demonstrated methods are supported only within their named stock, life stage and source scope. Remaining unverified topics are retained; a published operating setting is not automatically a physiological tolerance limit.
2026-10-03 practical keeping review: source-backed care guidance distinguished from research limits and optional breeding. Only actionable care gaps and identification blockers remain in this care queue. Scientific uncertainty is retained separately.
2026-10-04: existing practical water guidance surfaced here; numerical presets and scientific uncertainty are unchanged.
Acclimation and quarantine
MLL precaution: confirm identity and source temperature and salinity; obtain a species-appropriate transfer plan before acquisition.
Stocking safeguards
Aquarium setting: Home aquarium. Starvation risk: high.
Only after identity, reliable food supply and housing have been established.
- No acquisition without a sustainable species-appropriate food plan
- No unsupported numeric limits presented as guaranteed safe thresholds
Special risks
- Unstable rockwork after excavation
- Predation on tiny shrimp
- Incorrect goby pairing
- Copper exposure
Practical Keeping Review
The practical keeping questions have been reviewed against the cited sources. Read the source scope and remaining limits before applying the guidance.
Documented research limits and optional breeding questions are separate from everyday keeping. This review does not certify universal safe thresholds or complete lifetime validation.
Scientific Care Evidence
These findings distinguish a demonstrated method from an unanswered question. A supported finding applies within the named study or institutional scope; experimental settings are not universal safe limits.

Deliver meaty foods or bottom-feeder tablets where the shrimp can reach them, rather than assuming the goby feeds it adequately. The operator describes Amblyeleotris or Stonogobiops associations and occasional predation on tiny shrimp; verify the actual pairing and protect vulnerable livestock. A complete lifetime nutrient prescription and numerical stocking rule are not established.

Goby larval-culture reports involving co-housed Alpheus randalli do not provide a shrimp-rearing method. Successful adult feeding and burrow maintenance can be addressed separately from attempts to rear larvae. A species-matched larval feeding, settlement and survival protocol remains unverified.

Identification
Also traded as red-banded or candy-cane pistol shrimp. The two supplied photographs are source-identified Alpheus randalli; the existing unidentified Alpheus profile remains a separate record.
Habitat and Distribution
Burrows in sand or mud. Wild observations document an association with Stonogobiops nematodes, now linked from this profile. Species identity matters when considering a goby partner.
Feeding and Ecology
The enlarged claw produces a rapid snapping action. Field work records the shrimp consuming material from its goby partner; that observation does not remove its need for a captive food plan.
Reproduction and Evidence
The reviewed aquarium account discusses paired burrow residence. A verified complete larval-rearing method was not established here.
Aquarium Planning
The retailer recommends meaty foods and sinking tablets and notes possible predation on tiny shrimp. MLL precautions: stabilise rockwork before excavation, ensure food reaches the burrow, and verify a specific partner rather than promising universal goby compatibility.
Responsible Observation and Sourcing
MLL precaution: favour documented, responsibly sourced material and observation over speculative collection. Check lawful origin and current conservation information. A photograph alone does not establish a Canadian occurrence.
Evidence update and care limits
The association source links Alpheus randalli with Stonogobiops nematodes. Sharing a burrow does not mean the goby provides a nutritionally complete ration or that every introduced pair will accept one another. MLL monitoring plan: Record shrimp feeding independently of the goby and inspect burrow stability; do not replace a shrimp nutrition plan with the association alone.
