Where standard OEBTs display dark tiger striping across a blue body, the OERBT was created by selectively breeding stripeless OEBT specimens across successive generations. Through that process the striping disappeared entirely and the blue intensified, producing a solid deep royal blue shrimp with no banding and strikingly vivid orange eyes. The result is both more visually uniform than standard OEBT and more reliable to breed, as OERBTs produce notably fewer culls than their striped parent line. They are active, confident grazers that spend most of their time working algae and biofilm from plants, glass, and substrate, and they are more aggressive feeders than most dwarf shrimp. Adults reach approximately 1.2 inches.

Orange Eye Blue Tigers carry dark tiger stripes across the body; Orange Eye Royal Blue Tigers were developed specifically by selecting stripeless individuals until the banding disappeared entirely. The blue that remains is deeper and more intense than the base colour of striped OEBTs, reading as a uniform, saturated royal blue across the whole body.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eVivid orange eyes are the signature feature of the Orange Eye Tiger group.\u003c\/strong\u003e The bright orange eye colouration is the characteristic that names the entire OE Tiger line and is what makes these shrimp so immediately recognisable. In high-grade specimens the eyes are intensely orange, close to fluorescent against the deep blue body. Lower-grade shrimp in the broader Tiger group may show browner eyes, but the orange eye trait is the reason the line exists and is what buyers are paying for.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eProduces significantly fewer culls than standard OEBT.\u003c\/strong\u003e One of the practical advantages of the OERBT line is breeding consistency. Standard Orange Eye Blue Tigers throw a wide range of offspring including clear and poorly coloured shrimp. Because OERBTs were developed through generations of selecting against striping, the line is more stabilised and produces a higher proportion of well-coloured offspring. For a keeper looking to establish a colony rather than just maintain a display, this matters considerably.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eDark substrate and hardscape make the royal blue read at maximum depth.\u003c\/strong\u003e The solid blue body has real depth against dark aquasoil, dark hardscape, and green plant colour. Because there is no striping to break up the body, the colour reads as a single uniform block, which makes substrate choice more impactful for this variety than for patterned shrimp.\u003c\/span\u003e\n    \u003c\/div\u003e\n\n    \u003cspan class=\"section-label\"\u003eCare\u003c\/span\u003e\n    \u003ch2\u003eRequirements \u0026amp; Setup\u003c\/h2\u003e\n    \u003cdiv class=\"bullet-list\"\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eRemineralised RO water is required. This is an intermediate-level shrimp.\u003c\/strong\u003e OERBTs need controlled, stable water chemistry that tap water cannot reliably provide. Use RO water remineralised to GH 5 to 8 with KH 0 to 2 and TDS 100 to 200. Parameter stability matters more than hitting an exact number, so a steady pH of 7.0 is better than one drifting between 6.6 and 7.5.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eTigers prefer higher pH than most Caridina, sitting at 6.6 to 7.5.\u003c\/strong\u003e This is an important distinction. Taiwan Bee Caridina like Blue Bolt and Crystal Red require pH 5.8 to 6.8 over active buffering substrate. Tiger shrimp including OERBT prefer neutral to slightly alkaline conditions and do not need an active soil buffering the water down. This makes them noticeably easier to keep than Taiwan Bee lines and a good first step into Caridina keeping.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eRoom temperature suits them well. No heater required in most homes.\u003c\/strong\u003e OERBTs thrive at 64 to 78°F and generally do not need supplemental heating. Cooler water within that range tends to produce better colour and longer lifespans than sustained warmth at the upper end.\u003c\/span\u003e\n      \u003cspan class=\"bl-item\"\u003e\u003cstrong\u003eLow flow, well-cycled tank with aged water and abundant grazing surface.\u003c\/strong\u003e These shrimp are continuous grazers and need established biofilm to feed on.
