The Miyazakura × Himitsu Heiki base was reportedly managed as \u003cstrong data-start=\"1254\" data-end=\"1264\"\u003ePrince\u003c\/strong\u003e, which later helped produce Neptune and other Savanna lines. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1365\" data-end=\"1858\"\u003eNeptune combines traits from all three parent lines. \u003cstrong data-start=\"1418\" data-end=\"1432\"\u003eMiyazakura\u003c\/strong\u003e contributes complex color and blue lame contrast, \u003cstrong data-start=\"1483\" data-end=\"1500\"\u003eHimitsu Heiki\u003c\/strong\u003e contributes dense, high-coverage lame, and \u003cstrong data-start=\"1544\" data-end=\"1555\"\u003eSaboten\u003c\/strong\u003e contributes large reflective lame and fin shine.

Some individuals show stronger blue shine across the head and shoulders, while others show more silver or pale gold sparkle. They look best in \u003cstrong data-start=\"2160\" data-end=\"2187\"\u003eblack or dark gray tubs\u003c\/strong\u003e, which helps tighten the blue color and bring out the metallic lame. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"2296\" data-end=\"2715\"\u003eBecause Neptune carries aurora\/lame traits, offspring can show some variation. Breeders should select for strong blue head expression, dense back lame, clean body shape, and good reflective shine. Japanese sources also mention Neptune types such as standard Neptune, Golden Type, and Silver Type, so selective breeding is important if you want to keep the line leaning blue\/silver. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 data-section-id=\"1bh9odr\" data-start=\"2717\" data-end=\"2745\"\u003eTraits Seen in This Group\u003c\/h2\u003e\n\u003cp data-start=\"2747\" data-end=\"3078\"\u003e• Japanese import Neptune line\u003cbr data-start=\"2777\" data-end=\"2780\"\u003e• Blue-silver metallic body\u003cbr data-start=\"2807\" data-end=\"2810\"\u003e• Heavy lame sparkle across the back\u003cbr data-start=\"2846\" data-end=\"2849\"\u003e• Blue shine on head and shoulder area\u003cbr data-start=\"2887\" data-end=\"2890\"\u003e• Silver, blue, and subtle gold reflective scales\u003cbr data-start=\"2939\" data-end=\"2942\"\u003e• Normal body type\u003cbr data-start=\"2960\" data-end=\"2963\"\u003e• Clear\/translucent fins\u003cbr data-start=\"2987\" data-end=\"2990\"\u003e• Good top-view and side-view appeal\u003cbr data-start=\"3026\" data-end=\"3029\"\u003e• Best color in dark tubs or display containers\u003c\/p\u003e\n\u003ch2 data-section-id=\"1rv6da7\" data-start=\"3080\" data-end=\"3106\"\u003eBreeder \/ Project Notes\u003c\/h2\u003e\n\u003cp data-start=\"3108\" data-end=\"3455\"\u003eThis is a great strain for collectors and breeders who like blue-based medaka with high-end lame expression. For breeding, keep the fish with the strongest blue head, cleanest silver-blue body, densest back lame, and best body shape. Cull or separate fish that are too pale, too yellow\/gold, weak in lame, or lacking the Neptune blue\/silver shine.\u003c\/p\u003e\n\u003ch2 data-section-id=\"1xvzvcg\" data-start=\"3457\" data-end=\"3464\"\u003eCare\u003c\/h2\u003e\n\u003cp data-start=\"3466\" data-end=\"3779\"\u003eNeptune Medaka are kept like other Japanese ricefish. They do well outdoors in tubs or indoors in aquariums with clean, stable water. Strong natural sunlight or bright aquarium lighting helps bring out the best blue-silver shine and lame sparkle. Use a black or dark gray container for the best color development.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003ePhotos show the actual Neptune import group.
