Tambaqui

Tambaqui are generally peaceful but may compete for food. Keep with similarly sized or larger species to reduce stress. Avoid small or delicate fish that may be nipped. Provide ample space and hiding spots. Observe behavior to prevent dominance issues. Feed all fish adequately to reduce competition. Maintain water quality to reduce stress-induced aggression. Use visual barriers if necessary to separate individuals. Avoid overcrowding to promote harmony. Provide environmental enrichment to promote natural behavior.

Tambaqui require very large aquariums or ponds with stable, warm freshwater conditions and are not suitable for standard home tanks long-term. Maintain temperatures between 24–30 °C and a pH of 5.5–7.5. Soft to moderately hard water is preferred, with GH 2–10 and KH 2–8.

Provide extensive open swimming space, strong filtration, and regular water changes to support their rapid growth and high bioload. Use driftwood and rocks for environmental enrichment while keeping wide open areas free of obstruction.

Tambaqui are generally peaceful but can become stressed or competitive in confined environments. Monitor tank mates carefully and avoid overcrowding. Maintain a balanced diet and high water quality to promote long-term health and longevity.

Tambaqui are omnivores, feeding on fruits, vegetables, and small animals. Provide high-quality omnivore pellets as staple food. Supplement diet with fruits like melon, peas, and cucumbers. Offer occasional protein sources such as shrimp or fish. Feed 2-3 times daily according to size. Monitor feeding behavior to prevent competition. Avoid overfeeding to maintain water quality. Introduce variety to support optimal nutrition. Remove uneaten food to prevent decomposition. Adjust diet according to growth stages.

Tambaqui breed in large tanks mimicking floodplain conditions. Spawning occurs in shallow areas with submerged vegetation. Females lay eggs that are fertilized externally by males. Provide nutrient-rich diet for breeding pairs. Separate eggs or fry to prevent predation. Juveniles need soft, small foods initially. Gradually increase food size as fish grow. Monitor water quality to ensure fry survival. Maintain space to reduce adult-fry interactions. Adjust tank conditions as fry develop to mimic natural habitat.
