different hunting strategy from many actively swimming puffers.\n    Rather than constantly searching the aquarium for prey, it often buries almost its entire body beneath fine sand, leaving only the eyes and mouth visible before launching upward at passing food.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    The “Red” in Red Congo Puffer describes a desirable colour expression of \u003cem\u003eTetraodon miurus\u003c\/em\u003e, but colour is naturally variable.\n    Individual fish may shift between red, orange, reddish-brown, brown, grey, or darker tones depending on genetics,

where “inactive” does not mean unhealthy.\n    A properly settled \u003cem\u003eTetraodon miurus\u003c\/em\u003e may spend a large part of the day buried beneath the sand with only its eyes visible.\n

Burrowing is one of the defining behaviors of \u003cem\u003eTetraodon miurus\u003c\/em\u003e.\n    In nature, the fish positions itself beneath soft substrate and waits for prey to pass above.\n

This species is an ambush predator that hides beneath soft substrate and attacks prey from below.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\u003cstrong\u003eDoes a Red Congo Puffer stay red?\u003c\/strong\u003e\u003cbr\u003e\n    No colour is guaranteed permanently. The species can change between red, orange, brown, grey and darker shades depending on the individual, mood, substrate, surroundings and stress level.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\u003cstrong\u003eWhat substrate does a Red Congo Puffer need?\u003c\/strong\u003e\u003cbr\u003e\n    Fine, smooth sand is essential. It should be deep enough for the fish to bury most or all of its body without being scraped by coarse particles.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\u003cstrong\u003eCan Red Congo Puffer live with other fish?\u003c\/strong\u003e\u003cbr\u003e\n    We strongly recommend keeping it alone. It is a highly effective ambush predator and may bite or kill tank mates even if they appear compatible initially.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\u003cstrong\u003eCan I keep two Red Congo Puffers together?\u003c\/strong\u003e\u003cbr\u003e\n    We do not recommend it.
