Quick answer
X-ray Tetras live in Coastal Amazon rivers and floodplains. Within that range they pick microhabitats that supply cover, food (Omnivore (small invertebrates, plant matter)), water, and breeding sites — and they disappear where those features are lost.
Key takeaway

X-ray Tetra native habitat
X-ray Tetras (Pristella maxillaris) are tied to Coastal Amazon rivers and floodplains. Look for sites that match their diet (Omnivore (small invertebrates, plant matter)) and movement style; seasonal rains or prey shifts can expand or shrink local occupancy.
Microhabitats x-ray tetras prefer
Cover for resting, access to food, and safe breeding sites decide day-to-day use. Edge habitats can help adaptable populations but fail specialists that need continuous wild land.
How people change X-ray Tetra range
Farms, suburbs, and roads create opportunity for some individuals and lethal risk for others. Fragmentation without corridors isolates x-ray tetra groups and raises local extinction risk.
Conservation geography for x-ray tetras
Status in our guides: <strong>Least Concern</strong>. Protecting linked habitat often beats a single fenced reserve. Watch from a distance and never feed wild x-ray tetras.
Safety in schools
X-ray tetras are shoaling fish that feel secure in groups, moving and turning together in loose schools. A school confuses predators and lets the fish spot danger sooner, which is why they are most comfortable and colorful when kept in numbers.
A hardy survivor
Unusually for an Amazon tetra, this species tolerates a wide range of water conditions, including the slightly brackish coastal floodplains where many fish cannot live. That toughness has made it both a successful wild fish and a long-time favorite in home aquariums.
