The Amazon leaffish is a carnivorous fish from South America, famous for looking exactly like a drifting dead leaf. Its flattened body carries vein-like markings, and a small leaf-stalk-like projection on the lower jaw completes the disguise. Rather than chasing prey, it hangs almost motionless, creeps closer, and swallows its target whole the moment it comes within reach. Adults reach a maximum standard length of 8 cm, but the mouth is large and small fish count as food. It is rated as suitable for experienced keepers, so food and tank mates need careful planning.

- Care level
- Advanced
- Lifespan
- Few reliable data
- Size
- Up to 8 cm SL (FishBase)
- Temperature
- 22〜25℃
- Diet
- Piscivore (mainly live small fish)
- Water Temperature & Quality
- 22-25°C, pH 5.0-6.0, 5-8 dH (FishBase); Seriously Fish gives 23-29°C and pH 5.0-6.8. Soft, acidic water is essential.
- Aquarium
- Keep lighting dim with floating plants, add broad-leaved plants and driftwood for cover, and keep water movement minimal.
- Tank Mates & Compatibility
- Eats any fish it can swallow. A species tank is best; if mixing, limit companions to medium-sized plecos or armoured catfish.
- Diet & Feeding
- Accepts almost only live food. Juveniles take live bloodworm and small earthworms, but long term it needs live fish and can eat its own body weight daily. It rarely learns to take prepared foods.
- Breeding & Egg-laying
- In soft, acidic water above 25°C, up to 300 eggs are laid under a broad leaf and guarded by the male; they hatch in 3-4 days. Remove the female after spawning.
- Cautions
- Confirm you can supply live fish continuously before buying. Quarantine feeder fish in a separate tank first to avoid introducing disease.

7 things to know before welcoming a Amazon leaffish
1Ambush Hunter
The leaffish does not chase prey. It drifts like a dead leaf, creeps closer, and swallows its target whole in an instant. Think of it as a fish for watching camouflage and hunting behavior rather than active swimming, and your expectations will match reality better.
2Live Food Preferred
Because it strikes at moving prey, the leaffish is generally said to prefer live small fish, and many individuals are slow to accept prepared or frozen foods. Before bringing one home, make sure you can keep a steady supply of suitable feeder fish. Responses differ between individuals, so watch how each one eats and adjust accordingly.
3Not for Community Tanks
Although its maximum standard length is 8 cm, the mouth is large, and any fish small enough to fit is treated as food. Keeping it alone is the safest baseline rather than mixing it with other fish. Even fish of the same species can be a risk when there is a size difference, so be careful.
4Calm Tank, Good Cover
Avoid strong currents and overly bright lighting, and provide cover such as driftwood and plants so the fish can settle in. It spends long periods motionless, so a calm layout with gentle water movement suits it well.
5Handle Water Changes Gently
This South American fish is often described as preferring soft, slightly acidic water. Sudden changes in water quality can be a burden, so take your time with water changes and acclimation. Uneaten live food can also foul the water, so regular observation is essential.
6Quiet, Motionless Temperament
It spends most of its time nearly motionless, posing as a leaf while waiting for prey. Hurried movement in front of the tank or frequent handling of the tank can be stressful, so place it somewhere calm and watch quietly.
7Why It Suits Experienced Keepers
The leaffish is rated as suitable for experienced keepers. The reasons likely include securing live food, limits on tank mates, and the need for careful water management. Setting up the tank and arranging food in advance lets you welcome it home with confidence.
Frequently asked questions about Amazon leaffish
- Q.How long does an Amazon leaffish live?
- A.Reliable lifespan data is scarce, so no firm figure can be given. It is best to plan for long-term care and set up the tank properly before bringing one home.
- Q.How large does it get?
- A.According to FishBase, the maximum standard length is 8 cm. It is small, but the mouth is large, so any fish that fits inside can become prey.

- Q.Can it live with other fish?
- A.Generally no; keeping it alone is the safest approach. Any fish small enough to fit in its mouth may be eaten, and even fish of the same species can be at risk when their sizes differ.
- Q.Why does it look like a dead leaf?
- A.The look is thought to be camouflage that keeps small prey fish from becoming wary. Its flat body, vein-like markings, and leaf-stalk-like projection on the lower jaw all resemble a leaf drifting in the water.
