The black body never changes. As these shrimp grow and moult, the white pattern over it shifts into a luminous metallic blue or a deep emerald, depending on the individual. Other sellers list the same line as the Black Base Galaxy Boa; we name it for the colour you end up seeing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAbout the photo.\u003c\/strong\u003e The shrimp pictured is High or Collector grade. We ship unsexed juveniles, selected for early signs of metallic potential — treat the photo as the target, not the arrival. Coverage thickens, the body stripe sharpens and the metallic shift builds over successive moults. If you want the metallic look straight away, contact us about adults.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003clabel class=\"sz-acc__row\"\u003e\u003cinput type=\"radio\" name=\"sz-acc-metallic-black-boa\"\u003e\u003cspan\u003eColour \u0026amp; Care\u003c\/span\u003e\u003c\/label\u003e\n\u003csection class=\"sz-acc__panel\"\u003e\n\u003cp\u003eFive traits define a true Boa, and each keeps developing after arrival.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe hood:\u003c\/strong\u003e The defining hallmark — white spreading over the head and carapace, down to the cheeks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe body stripe:\u003c\/strong\u003e A thick “fishbone” stripe running down the back and reaching close to the edge of the belly — either a clean, straight-cut “boa” look or a saw-edged “jagged” look. Both are correct; the fewer breaks in it, the better.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShell thickness:\u003c\/strong\u003e A thick shell looks shiny and solid.

What changes is the tone of the white: at the size we ship there is already some blue in it, and it deepens and spreads from the head across the whole body pattern with age — blue on some, green on others. The strongest, most metallic tone typically arrives after a female has carried eggs (been “berried”) for the second time, at roughly three to four months old. Males colour up less than females.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpider legs:\u003c\/strong\u003e The body pattern carried onto the legs — black patches with white, and the white takes the same tone the body does, only subtler. Leg colour follows shell thickness, so the higher grades show it first.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eTwo things that are normal, not faults: the pattern keeps expanding and shifting as the shrimp ages, so a Boa looks better with time; and every shrimp arrives pale from the trip, colouring back up within hours to a few days.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003clabel class=\"sz-acc__row\"\u003e\u003cinput type=\"radio\" name=\"sz-acc-metallic-black-boa\"\u003e\u003cspan\u003eGrading\u003c\/span\u003e\u003c\/label\u003e\n\u003csection class=\"sz-acc__panel\"\u003e\n\u003cp\u003eWe grade by the traits that genuinely vary within a batch.
