The Aru IV locality form is the most widely kept Spotted Blue Eye, displaying a warm golden-yellow body with vivid golden-yellow fin extensions that have been selectively developed through captive breeding to show unusually elongated, dramatic streamer fins. Despite their tiny size, male Spotted Blue Eyes are among the most spectacular display fish in freshwater fishkeeping — the constant fin-fanning courtship display is mesmerizing to watch.\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 \u003cstrong\u003eSera Vipan Baby\u003c\/strong\u003e is the ideal daily staple for this tiny species — crush lightly before feeding.

This species inhabits slow-moving, heavily vegetated streams, billabongs, and swamps.
