Doxycycline belongs to the tetracycline antibiotic class and is one of the most versatile aquarium antibiotics available. Unlike standard tetracycline, doxycycline remains stable and effective in both freshwater and saltwater tanks — it does not bind to calcium ions and lose potency in hard or salt water. It is a top choice for treating tail rot, gill infections, swim bladder disease, and slow-healing wounds, and is widely considered one of the best all-around antibiotics for ornamental fish.\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003eAbout This Product\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDoxycycline Hyclate is a broad-spectrum tetracycline-class antibiotic effective against a wide range of gram-negative and gram-positive bacterial microorganisms. It works by inhibiting bacterial protein synthesis — preventing bacteria from reproducing and allowing the fish's immune system to clear the infection naturally.\u003c\/p\u003e\n\u003cp\u003eEach capsule or tablet contains USP-grade Doxycycline Hyclate 100mg, available in a 100-count. A key advantage of doxycycline over standard tetracycline is its stability in both freshwater and saltwater environments — it does not bind to the calcium and magnesium ions found in hard water and marine tanks, making it fully effective regardless of water chemistry. It is one of the most widely used and recommended antibiotics in ornamental fishkeeping.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eAlso commonly searched as: fish doxy, doxycycline for fish, aqua doxy equivalent, fish doxycycline 100mg, tetracycline fish antibiotic, aquarium doxycycline.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003eCommonly Treats\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eTail rot \u0026amp; fin rot\u003c\/li\u003e\n\u003cli\u003eGill disease \u0026amp; gill infections\u003c\/li\u003e\n\u003cli\u003eSwim bladder disease (bacterial)\u003c\/li\u003e\n\u003cli\u003eSlow-healing wounds \u0026amp; ulcers\u003c\/li\u003e\n\u003cli\u003eBacterial hemorrhagic septicemia\u003c\/li\u003e\n\u003cli\u003eDropsy\u003c\/li\u003e\n\u003cli\u003eColumnaris (mouth rot)\u003c\/li\u003e\n\u003cli\u003eInternal \u0026amp; systemic bacterial infections\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003eDirections for Use\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eDetermine your dose: Use one 100mg capsule or tablet per 10 gallons of aquarium water.
