What I Love About This Fish:

  • Beautiful spots and colorful tail
  • Hardy with plenty of personality
  • Possible to breed in the aquarium
  • Compatible with many other species in a spacious tank


This striking killifish, Aphyosemion Australe Cap Esterias BSWG 97-24 is a favorite for new and old killifish keepers alike! Males are particularly colorful boasting beautiful red spots with a beautiful orange and purple stripe along its fins. As with most killifish, females do not have the color patterns, but they make up for it in personality!

Aphyosemion Australe Cap Esterias BSWG 97-24 will thrive in any aquarium with a well sealed lid with any substrate choice.  This is an excellent candidate for a planted tank.  This is a generally compatible with most fish, but should not be kept with dwarf shrimp and other small, delicate invertebrates. They will co-exist with larger shrimp and snails in a big enough tank.  If spawning is desired, they will require a spawning mop.  If given the opportunity, they will breed in community tanks!

Feeding the Aphyosemion Australe Cap Esterias BSWG 97-24 is simple as they are an unfussy eater.  They prefer a carnivore based diet as their natural food is bugs! High-quality dry, frozen, and live meaty foods are an excellent choice of diet.  A quality and varied diet is key to keeping them looking their best.  The fish you are purchasing have been fed a high quality diet including baby brine shrimp.  Please ensure you have some prepared for their arrival. They may NOT eat flake food right away.
