Aquarium Setup Aphyosemion bivitattum “Lagos”
Aquarium Filtration
Use an air-driven sponge filter or gentle internal filter to maintain clean water without excessive current. Soft, slightly acidic water (pH 6.0–6.8) and low hardness (1–8 dGH) are ideal.
Aquarium Plants
Dense planting with fine-leaved species such as Java moss, Water Sprite, and Rotala is highly recommended. Floating plants like Salvinia or Amazon frogbit help diffuse light and mimic shaded forest streams.
Aquarium Lighting
Low to moderate lighting enhances colouration while creating a calm, natural environment. Avoid intense lighting, which may cause stress or encourage excessive algae.
Aquarium Heating
Maintain temperatures between 22–25 °C. Stability is essential, as these fish are sensitive to sudden changes. Use a precise heater, especially in cooler environments.
Aquarium Substrate
Use dark sand or fine gravel to replicate their natural habitat. A darker substrate also enhances their colours and supports live plant growth.
Aquarium Decorations
Incorporate driftwood, leaf litter, and spawning mops or caves for shelter and breeding. Visual breaks are essential to reduce aggression between males. Avoid sharp decor and maintain open swimming space in the mid to lower levels.
