Viral Reddit video: An adult snakehead swims beside a dense school of bright orange fry and briefly surfaces to drive away a bird. Both parents often guard their young for several weeks, improving juvenile survival. Commenters linked the behavior to the species' invasive risks — one recalled a released snakehead that led to a pond being drained. Experts warn never to release nonnative fish and urge reporting unusual sightings to wildlife authorities.
Watch: Protective Snakehead Guards Bright Orange Fry — A Parenting Trait That Fuels Its Invasion

A widely shared Reddit video captures an adult snakehead patrolling beside a tight school of bright orange fry and even briefly breaking the surface to chase off a circling bird.
Both parents of many snakehead species are known to fiercely guard their young for several weeks, keeping the fry together and protected from birds and predatory fish until they can fend for themselves. The behavior seen in the clip helps explain why snakehead populations can establish and expand rapidly when introduced into nonnative waters.
"Snakeheads are famously fiercely protective parents compared to most fish species. Both parents actively guard their orange/red school of 'fry' (babies) from birds and other predatory fish for several weeks until they are large enough to fend for themselves," the post explains.
Commenters reacted with fascination and concern. One recalled a local incident in which a released snakehead reportedly began preying on ducks, prompting authorities to drain the pond years later to remove the fish. That anecdote underlines the ecological risks when a top predator with strong parental care gains a foothold outside its native range.
Why This Matters
When more offspring survive thanks to parental protection, populations grow faster and become harder to control. For an invasive predator like the snakehead, that increased survival can raise pressure on native fish, waterfowl and other wildlife, disrupt food webs, and complicate management efforts.
What You Can Do
- Never release aquarium pets, bait fish, or nonnative species into ponds, lakes, or streams.
- Learn which fish are native to your region so you can spot unusual species early.
- Report unusual fish sightings to local wildlife or fisheries officials rather than attempting to remove them yourself.
Once an invasive species becomes established, removal is often expensive, disruptive and sometimes impossible. The Reddit clip offers a striking glimpse of natural parenting behavior — and a reminder of how that same behavior can become an ecological advantage when species move beyond their native ranges.
