It can grow up to 45 cm in length, while juveniles are described as “vivid yellow tiny swimming dice with crisp black polka dots”. Their diet consists mainly of algae, sponges, crustaceans, molluscs, worms and small fish. And when stressed or threatened, Yellow Boxfish can secrete a toxic substance (ostracitoxin) through their skin, which can poison nearby fish. Definitely a risky tank mate for your home aquarium.\u003c\/p\u003e\n\u003cp\u003eThis year’s ink is quintessentially Robert Oster: Goldilocks flow (not too wet, not too dry, just right), well-behaved, extremely readable (for a yellow), and fantastic for watercolour and art.\u003c\/p\u003e\n\u003cp\u003eCrafted in \u003cstrong\u003eSouth Australia\u003c\/strong\u003e, these inks offer smooth flow, subtle shading, and a refined palette suited to both everyday writing and thoughtful creative work.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eA drink for your pen.\u003c\/em\u003e\u003c\/p\u003e\n\u003c!-- SECTION 2 — About Robert Oster and Robert Oster Inks --\u003e\n\u003cp\u003e\u003cstrong\u003eThe Remarkable Robert Oster\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRobert Oster is a South Australian colour creator whose inks reflect his passion, creativity, and deep connection to the Australian landscape.
