Aquarium care
Specialist leaf-mimic ambush predator requiring soft acidic water, dim lighting, floating plants, broadleaf cover, and almost no current. Species tank strongly preferred. Will generally accept only live foods long-term (feeder fish / occasional river shrimp); not for keepers unwilling to supply live prey. Sensitive to water-quality declines and very flighty.
Feeding
Obligate live-food piscivore in practice; juveniles may take bloodworm/earthworms but adults typically need live fish. Can consume roughly their own body weight daily.
Compatibility
Species tank preferred; SF allows medium loricariids/armoured catfish. Predatory toward anything swallowable.
