Common name
Amphipods
Scientific name
Amphipoda spp.
Category
Live-food culture
Group
Crustacean live foods
Environment
Species-specific freshwater, brackish or marine culture
Origin
Worldwide; culture identity and source must be documented to species or the narrowest practical taxon
Care level
Intermediate
Adult size
Unknown at group level — amphipod size varies greatly by species
Expected lifespan
Unknown at group level
Minimum housing
Dedicated escape-resistant culture vessel sized to the species and harvest goal; keep at least one separate backup culture
Temperature
Unknown at group level — species-specific
pH
Unknown at group level — species-specific
Hardness / minerals
Unknown at group level — match the identified freshwater species or use complete marine saltwater for marine taxa
Salinity
Species-specific; freshwater, brackish and marine amphipods are not interchangeable
Lighting
Low to moderate, matched to any algae or macroalgae used as feed
Placement / zone
Dedicated culture area away from display aquaria and chemical sprays
Filtration
Use no strong conventional intake. Provide species-appropriate biological surface area, a guarded air-driven sponge or measured water renewal, and retain juveniles during every harvest or water change.
Aeration
Provide gentle continuous aeration sufficient to keep oxygen stable without ejecting animals, drying splash zones or collapsing delicate shelters. Increase exchange as density and feeding rise.
Maintenance
Feed measured clean material, remove uneaten food and mortalities, thin before crowding, inspect under magnification for contaminants, harvest only a minority, and maintain a physically separate backup culture with separate tools.

Identity and search names

Order-level live-food culture guide only. Amphipoda contains many unrelated freshwater, brackish and marine species; record the narrowest credible identity, source and salinity and do not treat one culture recipe as universal.

Search names: Scuds, Gammarids, Marine amphipods, Freshwater amphipods

Environment and housing

Use a dedicated lidded vessel with species-appropriate aeration, biological surface area and removable shelters. Protect air lines and drains from escape.

Social structure: Culture density is species-specific

Feeding and nutrition

Feeding ecology: Species-specific detritus, algae, biofilm, plant matter or prepared aquaculture feeds

Feeding routine: Feed small measured amounts and remove leftovers before fouling

Breeding, reproduction or spread

Females brood eggs and developing young in a ventral brood pouch; juveniles emerge as miniature amphipods rather than free-swimming larvae.

Detailed care and app-ready planning

Identity scope
Order-level live-food culture guide only. Amphipoda contains many unrelated freshwater, brackish and marine species; record the narrowest credible identity, source and salinity and do not treat one culture recipe as universal.
Adult size and space
Adult size and density are species-dependent. Use a dedicated escape-resistant vessel with enough submerged surface, shelters and oxygen for the full mature culture, plus at least one physically separate backup.
Social structure
Mixed-age breeding colony. Retain males, brood-bearing females and juveniles; do not harvest so heavily that reproduction collapses.
Swimming zone or placement
Bottom, surfaces, shelters and water column according to species. Keep all occupied zones oxygenated and accessible without unguarded drains or intakes.
Feeding ecology
Species-dependent detritivory, algivory, scavenging or omnivory. Nutritional value reflects both amphipod identity and the clean feed used to condition the culture.
Feeding plan
Offer small measured portions of clean species-appropriate algae, biofilm, plant material or prepared aquaculture feed. Add more only after the previous feed is consumed without odour or bacterial clouding.
Water stability
Keep ammonia and nitrite at zero, oxygen adequate and salinity stable. Culture-specific numbers remain unknown until the species is identified.
Habitat structure
Dedicated lidded vessel with removable shelters, high biological surface area, species-appropriate water, escape control and no shared wet equipment.
Compatibility plan
Culture alone. Do not combine unidentified amphipods, wild water, predators, hydra, planaria, fish parasites or display-aquarium stock.
Breeding or reproduction plan
Females brood eggs and young in a ventral marsupium. Maintain mixed ages, stable water and shelter; harvest a minority and preserve a separate backup rather than chasing maximum density.
Quarantine
Keep new starter cultures isolated and observe several generations before combining or feeding valuable stock.
Welfare checks
Check activity, moulting, brood-bearing females, mortality, odour, oxygen, waste and contamination.
Biosecurity and release
Never release amphipods, culture water, wet feed, substrate or equipment rinse-water. Securely kill and contain unwanted cultures and verify current Australian and state requirements before import, collection, sale or movement.
Main risk
Using an unidentified or contaminated culture and spreading predators, parasites or invasive organisms.
Adult projected load
Project load from the entire mature culture, feed input, moults, faeces, mortalities and decomposing shelters. Culture biomass can rise rapidly and exhaust oxygen before animal numbers look excessive.
Filtration
Use no strong conventional intake. Provide species-appropriate biological surface area, a guarded air-driven sponge or measured water renewal, and retain juveniles during every harvest or water change.
Aeration
Provide gentle continuous aeration sufficient to keep oxygen stable without ejecting animals, drying splash zones or collapsing delicate shelters. Increase exchange as density and feeding rise.
Maintenance
Feed measured clean material, remove uneaten food and mortalities, thin before crowding, inspect under magnification for contaminants, harvest only a minority, and maintain a physically separate backup culture with separate tools.
Overridable warnings
Non-overridable: do not mix salinity types or unidentified cultures, share wet tools with display systems, depend on one vessel, or release live culture material. A knowledgeable user may vary vessel size, shelter and feed only when identity, oxygen, purity and containment remain demonstrably protected.
Identity
Order Amphipoda contains many freshwater, brackish and marine species. Record the supplier, source water and the narrowest credible identification.
Culture Vessel
Use a dedicated lidded vessel with species-appropriate aeration, biological surface area and removable shelters. Protect air lines and drains from escape.
Culture Feed
Use clean species-appropriate algae, biofilm, detrital plant material or measured prepared aquaculture feed. Remove uneaten food before it fouls the medium.
Harvest
Harvest only a small fraction at a time with a fine net or removable shelter. Rinse cultured amphipods in clean matched water before feeding.
Backup
Maintain at least one physically separate culture using separate tools. Restart from the backup rather than repeatedly rescuing a crashing vessel.
Water Medium
Use dechlorinated freshwater for freshwater species or correctly mixed marine saltwater for marine species. Exact temperature, pH and minerals are unknown without a species identity.
Contamination
Inspect for hydra, planaria, predatory larvae, fish parasites, snails, algae blooms, mould and chemical contamination. Never add wild water directly to a culture.
Use
Potential live food for suitably sized fish and other aquatic predators. Nutritional value varies with species and feed, so amphipods should be part of a varied diet.
Reproduction
Females brood eggs and developing young in a ventral brood pouch; juveniles emerge as miniature amphipods rather than free-swimming larvae.
Culture Density
Unknown as a universal figure. Thin the culture before oxygen falls, waste accumulates or growth slows.
Biosecurity and release
Never release amphipods or culture water. Bag and freeze or otherwise securely kill unwanted cultures before disposal according to local rules.

Compatibility, welfare and risk

Compatibility: Culture alone; predators, hydra, planaria and mixed unidentified crustaceans can collapse or contaminate production

Welfare: Maintain active mixed life stages, normal moulting, brood-bearing females, clean odour and stable oxygen. A motionless, foul-smelling or single-stage culture is already failing.

Main warning: “Amphipods” is not one culture species. Do not mix freshwater and marine taxa, wild-collected organisms or unidentified cultures into display systems.

Biosecurity and release

Never release amphipods, culture water, wet feed, substrate or equipment rinse-water. Securely kill and contain unwanted cultures and verify current Australian and state requirements before import, collection, sale or movement.
