The golden body with red spots and flowing lyretail makes this one of the most elegant killifish in the hobby. \u003cem\u003eAphyosemion australe\u003c\/em\u003e is one of the most popular and accessible killifish in the hobby — colorful, manageable, and genuinely rewarding. As a non-annual species it lives considerably longer than the dramatic but short-lived \u003cem\u003eNothobranchius\u003c\/em\u003e, making it an excellent introduction to killifish keeping.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin-bottom:16px;background-color:#e0f0f8;border:1px solid #b0d0e8;padding:14px 18px;color:#0a2a3a;\"\u003e\u003cstrong\u003eFeeding \u0026amp; Care Tip:\u003c\/strong\u003e Killifish are carnivores that thrive on a varied diet of frozen and freeze-dried foods. \u003cstrong\u003eHikari Frozen or Freeze-Dried Bloodworms\u003c\/strong\u003e, \u003cstrong\u003eHikari Frozen or Freeze-Dried Baby Brine Shrimp\u003c\/strong\u003e, and \u003cstrong\u003eHikari Frozen Daphnia\u003c\/strong\u003e form the core diet — offer variety rather than relying on a single food. \u003cstrong\u003eHikari Micro Pellets\u003c\/strong\u003e are accepted by most killifish as a dry staple. Feed small amounts 2–3 times daily. Varied feeding is especially important for annual species given their compressed lifespan.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin-bottom:16px;color:#2c2c2c;\"\u003eNative to slow-moving streams, swamps, and pools of coastal West Africa — Cameroon, Gabon, and surrounding areas. Inhabits heavily vegetated, shaded water with soft, slightly acidic conditions. \u003cem\u003eAphyosemion australe\u003c\/em\u003e is a non-annual killifish — it lives in permanent water bodies and breeds in the standard fashion without requiring a dry period for eggs. Lifespan of 2–3 years in good conditions.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin-bottom:16px;color:#2c2c2c;\"\u003eKeep one male with two or more females. Males are territorial with each other in small spaces but can be kept in groups in larger, well-planted aquariums. Peaceful with most small, peaceful community fish. Dense planting and floating plants are appreciated.\u003c\/p\u003e\u003cp style=\"font-family:Georgia,serif;font-size:1.05em;line-height:1.8;margin-bottom:24px;color:#2c2c2c;\"\u003eBreeding is straightforward compared to annual killifish — eggs are deposited on plants, spawning mops, or fine substrate and receive no parental care. Remove eggs or fry to a separate container to prevent predation. No dry period is required — eggs can be incubated in water. Lyretail forms require clean water and gentle filtration to maintain fin integrity — strong currents damage the extended rays.\u003c\/p\u003e\u003ch3 style=\"font-family:Georgia,serif;font-size:1.05em;font-weight:normal;letter-spacing:0.1em;text-transform:uppercase;color:#0a2a3a;border-top:1px solid #b0d0e8;padding-top:18px;margin-bottom:14px;\"\u003eCare \u0026amp; Ideal Parameters\u003c\/h3\u003e\u003ctable style=\"width:100%;border-collapse:collapse;font-family:Arial,Helvetica,sans-serif;font-size:0.92em;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:9px 14px;background-color:#e0f0f8;color:#0a2a3a;font-weight:600;width:38%;border:1px solid #b0d0e8;\"\u003eDifficulty\u003c\/td\u003e\n\u003ctd style=\"padding:9px 14px;background-color:#e0f0f8;color:#2c2c2c;border:1px solid #b0d0e8;\"\u003eEasy — Moderate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:9px 14px;background-color:#ffffff;color:#0a2a3a;font-weight:600;width:38%;border:1px solid #b0d0e8;\"\u003eTemperament\u003c\/td\u003e\n\u003ctd style=\"padding:9px 14px;background-color:#ffffff;color:#2c2c2c;border:1px solid #b0d0e8;\"\u003ePeaceful — males mildly territorial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:9px 14px;background-color:#e0f0f8;color:#0a2a3a;font-weight:600;width:38%;border:1px solid #b0d0e8;\"\u003eTypical Adult Size\u003c\/td\u003e\n\u003ctd style=\"padding:9px 14px;background-color:#e0f0f8;color:#2c2c2c;border:1px solid #b0d0e8;\"\u003e2.5 inches (6.3 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:9px 14px;background-color:#ffffff;color:#0a2a3a;font-weight:600;width:38%;border:1px solid #b0d0e8;\"\u003eMin.
