Everything we sell is intended for ornamental aquarium fish. These products are not for human use, not for use in animals raised for food, and not a substitute for veterinary care. If a pet other than an ornamental fish needs treatment, please consult a licensed veterinarian, who can prescribe the correct product and dose for that animal.

The right choice depends on the condition. Broad-spectrum options such as amoxicillin or cephalexin are common starting points for general bacterial problems like fin rot and skin ulcers. Doxycycline and minocycline are used for respiratory and gill issues. Metronidazole targets anaerobic organisms and protozoan parasites such as Hexamita. Ciprofloxacin and levofloxacin are used against gram-negative organisms including Pseudomonas. Our treatment packs group these by condition if you would rather not pick individually.

The milligram figure is the amount of active ingredient per capsule or tablet — a 500 mg capsule contains twice as much as a 250 mg capsule. Which strength suits you depends on your tank volume and the number of doses you expect to need. Larger tanks, ponds and fish rooms generally get better value from the higher strengths and the 100-count bottles.

They can. Antibacterial treatments reduce populations of the nitrifying bacteria that drive your tank's nitrogen cycle, and broad-spectrum products tend to have more effect than narrow ones. Many aquarists treat in a separate hospital tank for this reason, monitor ammonia and nitrite closely during a course, and plan for extra water changes afterwards.
