It does not guarantee full removal, and we will not pretend otherwise.\u003c\/strong\u003e Ich is only killed in its free-swimming stage, and a short treatment window can miss cysts entirely; worm burdens can survive a single dose. Clearing an animal takes the full quarantine window — 40 to 90 days depending on the species — which is exactly what the \u003ca href=\"\/collections\/quarantine-program\"\u003eQuarantined listing\u003c\/a\u003e is for. This tier buys you a lower parasite load and a fish we have watched eat, not a cleared animal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWe condition the fish on our end.\u003c\/strong\u003e Every animal we medicate is brought back onto prepared food on our own systems and is eating before it leaves — in practice it is rare for a lightly medicated fish to ship out and arrive sick. Do the same at your end: get it eating in your aquarium before you count it settled.\u003c\/p\u003e\u003ch3\u003eWhen it ships\u003c\/h3\u003e\u003cp\u003ePlan on \u003cstrong\u003e3–5 days\u003c\/strong\u003e on our systems for the treatment course, and it does not leave until it is eating. \u003cstrong\u003eIf the animal is not already in our systems we source it first — allow up to two weeks for it to reach us before that clock starts.\u003c\/strong\u003e From the day you order, plan on roughly two and a half weeks in total.\u003c\/p\u003e\u003ch3\u003eThe guarantees\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShipped orders:\u003c\/strong\u003e 24-hour live guarantee from confirmed delivery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn-store pickup:\u003c\/strong\u003e 7-day live guarantee — bring a water sample from your aquarium so we can test it before your livestock goes home with you.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWant the full program — treated, observed, confirmed eating, and covered for 28 days on pickup?

The T.R. (tank-raised) designation means these are captive-bred specimens, not imports, which translates directly to faster acclimation, better disease resistance, and a fish that adjusts to captive water parameters without the stress load a wild-caught specimen carries from a months-long collection and shipping chain.\u003c\/p\u003e\u003cp\u003eCorydoras are social, shoaling catfish from South American streams and river margins — \u003cem\u003eCorydoras\u003c\/em\u003e species number in the hundreds across the genus — and they do everything better in groups. A single cory is a fish that spends its time looking for company; a group of six or more is a coordinated bottom-cleaning crew that visibly schools and communicates through fin posture in a way that’s genuinely interesting to watch. The gold laser grade pairs that social behavior with a color that reads as surprisingly vivid at substrate level where most golden-toned fish never venture.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eScientific name:\u003c\/strong\u003e Corydoras sp.
