Two-banded killifish
Aphyosemion bivittatum
The body is elongated and slightly laterally compressed. The base coloration is brown-yellow with two characteristic dark longitudinal bands: one median and one lower. The fins are often tinted red or orange in males. Females are duller. This species is very active and generally stays near the surface. It is peaceful and can coexist with other small calm fish. Adult size is 5-6 cm. Lifespan is 2-3 years. Reproduction is easy: eggs are laid on fine-leaved plants or mops.

Care notes
A 30-liter aquarium is sufficient for a pair or trio. The tank should be planted with shaded areas and floating cover. Filtration should be gentle (sponge). Ideal temperature is 22-26°C, pH 6.0-7.0, hardness 2-8 dGH. Diet is carnivorous: artemia, daphnia, bloodworms, small insects. Avoid overly large or aggressive fish. Water changes should be moderate (10-15% weekly). A lid is essential. Reproduction is simple: remove eggs to incubate separately.
