It was sold in the hobby for years as \u003cem\u003ePseudomugil paskai\u003c\/em\u003e before being formally described as a distinct species in 2016. The colouration of adult males in peak condition is extraordinary for a fish barely 1.2 inches long -- the body glows red to orange-red, the eyes are a vivid electric blue, the fins carry scattered black spots and pale yellow-white markings on the tips, and a vivid blue iridescent stripe runs along the dorsal surface. In subdued lighting against dark substrate the fish appears to emit its own light. Native to blackwater habitats stained with tannins from leaf litter, it performs best in soft, slightly acidic water and a heavily planted setup with floating plants to diffuse overhead lighting. One of the most shrimp-compatible fish in the hobby due to its tiny mouth and peaceful disposition. Note: the species is IUCN Endangered in the wild due to habitat destruction -- most available specimens are captive-bred, which is strongly preferred.\u003c\/p\u003e\n    \u003cdiv class=\"stat-row\"\u003e\n      \u003cdiv class=\"stat-card\"\u003e\n\u003cspan class=\"stat-value\"\u003e5.5–7.5\u003c\/span\u003e\u003cspan class=\"stat-label\"\u003epH\u003c\/span\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"stat-card\"\u003e\n\u003cspan class=\"stat-value\"\u003e1–10\u003c\/span\u003e\u003cspan class=\"stat-label\"\u003eGH (dGH)\u003c\/span\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"stat-card\"\u003e\n\u003cspan class=\"stat-value\"\u003e75–82°F\u003c\/span\u003e\u003cspan class=\"stat-label\"\u003eTemperature\u003c\/span\u003e\n\u003c\/div\u003e\n      \u003cdiv class=\"stat-card\"\u003e\n\u003cspan class=\"stat-value\"\u003e1.2 in\u003c\/span\u003e\u003cspan class=\"stat-label\"\u003eMax Size\u003c\/span\u003e\n\u003c\/div\u003e\n    \u003c\/div\u003e\n    \n    \u003cspan class=\"section-label\"\u003eAppearance \u0026amp; Display\u003c\/span\u003e\n    \u003ch2\u003eThe Glow Effect\u003c\/h2\u003e\n    \u003cdiv class=\"bullet-list\"\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eGlowing red to orange-red body with electric blue eyes -- appears fluorescent under aquarium lighting.\u003c\/strong\u003e The body colouration of a peak-condition male \u003cem\u003eP. luminatus\u003c\/em\u003e has a neon quality that few freshwater fish match at any size. The red-orange is saturated and vivid, the blue eyes create a startling colour contrast at the head, and the overall impression under appropriate lighting is of a fish generating its own light rather than reflecting ambient light. This effect is most pronounced in subdued lighting against a dark substrate -- the brighter the tank, the more the colour washes out.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eScattered black spots on fins with white to yellow markings on the tips -- intricate fin patterning at close range.\u003c\/strong\u003e The fins of adult males carry scattered dark spots against a pale base, with white to yellow-white markings on the fin tips and the upper edge of the pectoral fins.

The blackwater aesthetic -- tannins, Almond Leaves, dark substrate -- suits both the fish and Caridina shrimp simultaneously.

The glowing red-orange of the fish moving through tannin-stained water above the patterned CRS below, with the warm dark aesthetic of the blackwater setup unifying everything, creates a display that reads as complete and intentional from every viewing angle. Feed small live or frozen foods daily for peak colour, maintain stable soft water, and this setup delivers an ongoing visual reward that few other fish-and-shrimp combinations can match.\u003c\/p\u003e\n\u003c\/div\u003e\n    \u003ca href=\"\/collections\/freshwater-fish-parent\" class=\"cta-block\" title=\"🐠 browse more freshwater fishbrowse our full freshwater fish collection. →\" aria-label=\"🐠 browse more freshwater fishbrowse our full freshwater fish collection. →\"\u003e\u003cspan class=\"cta-icon\"\u003e🐠\u003c\/span\u003e\u003cdiv class=\"cta-text\"\u003e\n\u003cstrong\u003eBrowse more freshwater fish\u003c\/strong\u003e\u003cp\u003eBrowse our full \u003cspan style=\"color:#F40909;font-weight:500;\"\u003eFreshwater Fish collection\u003c\/span\u003e.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cspan style=\"color:rgba(255,255,255,0.4);font-size:1.4rem;\"\u003e→\u003c\/span\u003e\u003c\/a\u003e\n    \u003cdiv class=\"policy-bar\"\u003e\n      \u003cspan\u003eBefore placing your order, please review our\u003c\/span\u003e\n      \u003ca href=\"\/pages\/doa-policy\" title=\"Doa policy\" aria-label=\"Doa policy\"\u003eDOA Policy\u003c\/a\u003e\n      \u003ca href=\"\/pages\/shipping-info-practices\" title=\"Shipping info\" aria-label=\"Shipping info\"\u003eShipping Info\u003c\/a\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/body\u003e","brand":"Superior Shrimp \u0026 Aquatics","offers":[{"title":"1","offer_id":45089097482448,"sku":null,"price":9.0,"currency_code":"USD","in_stock":true},{"title":"3","offer_id":45089097515216,"sku":null,"price":27.0,"currency_code":"USD","in_stock":true},{"title":"6","offer_id":45089097547984,"sku":null,"price":54.0,"currency_code":"USD","in_stock":true},{"title":"12","offer_id":45089097580752,"sku":null,"price":108.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/2895\/9184\/files\/paskali-red-neon-pseudomugil-luminatus-placeholder-graphic-540.webp?v=1785437655","url":"https:\/\/www.superiorshrimpaquatics.com\/products\/red-neon-blue-eye-rainbowfish-pseudomugil-luminatus","provider":"Superior Shrimp \u0026 Aquatics","version":"1.0","type":"link"}
