A western Atlantic Berghia documented from Argentina, Brazil and Caribbean material, with captive-care evidence still limited. The taxonomic review separates this accepted species from superficially similar Berghia. Older assignments of western Atlantic specimens were sometimes incorrect, so colour alone is insufficient.

Aquarium suitability not established
Aquarium suitability has not yet been established for this record. Available observations do not constitute an acquisition recommendation.
The species-specific aquarium reference reports no successful captivity accounts. A primary Argentine prey lead exists, but does not demonstrate routine aquarium suitability; evaluate this separately from the commercially cultured B. stephanieae.
MLL precaution: keep this as a specialist natural-history profile until identification, food continuity and appropriate housing can be demonstrated. A standard reef care rating would hide the present evidence gaps. Numerical temperature, salinity, pH, enclosure and stocking limits remain unverified in this review. Published culture conditions and retailer recommendations are not proven tolerance limits.

These source findings support institutional assessment, identification or wildlife research. They are separate from aquarium-care completion.
Source findings and their limits
A named locally ingested prey provides a source-scoped feeding candidate, while complete captive nutrition and stocking validation remain unresolved.
Source limit: The candidate is supported by preliminary wild dietary evidence, not a demonstrated sustained captive ration or stocking density; successful ordinary keeping remains unestablished.
Sources: Garese et al., 2009 cleptocnidae · Carmona et al., Berghia revisionThe museum discussion refers readers to commercial Berghia breeding, but does not demonstrate a complete rissodominguezi-specific rearing protocol. Confirm adult identity and prey first, and retain larval culture as a separate research task. Egg handling, larval food, settlement and full-cycle survival for verified stock remain unverified.
Source limit: Egg handling, larval food, settlement and full-cycle survival for verified stock remain unverified.
Sources: Australian Museum: Berghia rissodominguezi correspondenceHabitat and suitability context are available; numerical operating guidance is not demonstrated.
Source limit: A measured species-matched maintaining-water and enclosure record remains missing. This suitability review is not a claim that the species cannot ever be maintained.

The taxonomic review separates this accepted species from superficially similar Berghia. Older assignments of western Atlantic specimens were sometimes incorrect, so colour alone is insufficient.
Habitat and Distribution
The reviewed records include its Argentine origin and later Brazilian and Caribbean material. These regional records do not determine the collection location of the supplied photograph.
Feeding and Ecology
A tested captive prey list and sustainable feeding plan were not established in this review. A family or genus name cannot justify copying B. stephanieae’s food requirements.
Reproduction and Evidence
Published taxonomy describes reproductive anatomy. A complete species-specific captive-culture protocol remains unresolved.
Aquarium Planning
MLL precaution: keep this as a specialist natural-history profile until identification, food continuity and appropriate housing can be demonstrated. A standard reef care rating would hide the present evidence gaps.
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.
Deeper care evidence review
The molecular study finds B. rissodominguezi and B. stephanieae to be related but distinct species, supported by morphological differences. Close relationship is not evidence of identical prey acceptance or rearing requirements. A species-matched feeding and lifecycle protocol remains unresolved. Remaining evidence gaps: Corroborated numerical water and enclosure limits; Complete long-term captive nutrition and stocking validation; A complete population- and life-stage-specific rearing protocol. Full lifetime husbandry remains unverified.
