{"product_id":"t-r-gold-laser-corydoras-medium","title":"T.R. Gold Laser Corydoras","description":"\u003cp\u003e\"Laser\" strains in the cory trade describe a selectively bred metallic sheen — a reflective quality layered into the skin that causes the fish to catch light at angles that wild-type corys don't, almost like a moving mirror embedded in the body. 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.
