Fix Flox (Fish Flox) Ciprofloxacin Capsules - Fish & Bird Antibiotic 500 mg
Fix Flox 500 mg (Ciprofloxacin) (often called Fish Flox, Fish Flox Forte, or Aqua Cipro in the hobby community) is a trusted, broad-spectrum fish and bird antibiotic in capsule form for ornamental aquarium fish and non-food pet birds. This ciprofloxacin 500 mg option from the Aqua Soma Labs Fix range is commonly used by hobbyists to help manage bacterial issues in freshwater and saltwater aquariums, including problems often described as fin and tail rot, ulcer-like sores, red sores, columnaris-type patches, or septicemia-type signs that may be associated with gram-negative bacteria (such as Aeromonas or Pseudomonas) and, in some cases, susceptible gram-positive organisms.
Ciprofloxacin is a fluoroquinolone antibiotic that targets key bacterial enzymes involved in DNA replication (commonly described as DNA gyrase and topoisomerase IV), which can slow bacterial growth in susceptible organisms when used as directed.
Fix Flox from Aqua Soma Labs supplies 500 mg ciprofloxacin per capsule and is available in bottles of 30-count or 60-count, giving hobbyists flexible options whether they maintain a single hospital tank, multiple community aquariums, or a busy loft or aviary. It is a convenient choice when you need ciprofloxacin for fish or ciprofloxacin for birds and prefer one product that fits both aquatic and avian collections. If you are searching for fish cipro or fish ciprofloxacin 500 mg capsules, Fix Flox is the targeted ciprofloxacin option in the Fix lineup.
Important Notice: This product is intended for aquarium and ornamental fish and pet birds only. It is not for human consumption or for animals used for food. We do not sell or recommend this product for human use.
Use Fix Flox when you notice early signs of bacterial stress such as persistent fin breakdown, worsening ulcers, red sores or red ulcerations, red streaking, sudden swelling that looks dropsy-like, or a rapid decline in activity or appetite in fish. For pet birds, ciprofloxacin for birds should be used only under avian veterinary guidance when a veterinarian determines ciprofloxacin is appropriate.
Addressing potential bacterial issues early with ciprofloxacin treatment, together with stable water quality, good aeration, suitable housing, and advice from an aquatic or avian professional when available, helps support a steadier, healthier aquarium or aviary.

What Are the Ingredients in Fix Flox (Fish Flox) Ciprofloxacin 500 mg Capsules?
-
Active ingredient: Ciprofloxacin (500 mg per capsule)

For pet birds, use only under avian veterinary guidance.

Side Effects & Safety Tips for Fix Flox (Fish Flox) Ciprofloxacin 500 mg
When used as directed, Fix Flox is commonly used by hobbyists for ornamental fish and non-food pet birds. Possible side effects are often related to temporary stress from treatment, water quality shifts, or incorrect dosing. As with any antibiotic, misuse or prolonged use can increase the risk of antibiotic resistance.
-
Fish (possible side effects): Some fish may show temporary stress or hiding behavior, reduced appetite, or mild lethargy during treatment. Temporary changes in water clarity or color may also occur after adding medication. If fish show severe distress such as rapid gill movement, loss of balance, gasping at the surface, or lying on the bottom, stop treatment, improve aeration, and seek aquatic professional guidance.
-
Birds (safe use): Ciprofloxacin for birds should be used only under avian veterinary guidance. Possible reactions can include reduced appetite, lethargy, or loose or changed droppings, especially if the bird is sensitive or the dose is not appropriate. Discontinue use and contact an avian veterinarian if your bird appears unwell or stops eating.
-
Invertebrates: Whenever possible, treat affected fish in a separate hospital tank, especially if the display tank contains shrimp, snails, or other invertebrates that may be more sensitive to medications.
-
Safe use in your system: Treat in a hospital or quarantine tank whenever you can. Remove activated carbon (and other chemical filtration media) and turn off UV sterilizers during treatment, as they can reduce medication levels. Maintain strong aeration and monitor ammonia, nitrite, and temperature closely. Avoid mixing Fix Flox with other antibiotics unless advised by a professional.
-
Warnings: Avoid overdosing. Antibiotics may harm fish or disrupt beneficial bacteria in the aquarium, especially in the main display system, so careful dosing and water quality monitoring matter.
-
Important safety warning: Fix Flox is intended for ornamental aquarium fish and non-food pet birds only. It is not for human use and not for animals raised for food. Always follow the directions on the label.
-
Storage: Keep capsules tightly closed in a cool, dry place away from direct sunlight, and keep out of reach of children and pets.

Fix Flox (Fish Flox) Ciprofloxacin 500 mg FAQs
Is Fix Flox the same as "fish cipro"?
Fix Flox is a ciprofloxacin-based product used by hobbyists for ornamental fish. The phrase "fish cipro" is a common hobby term for ciprofloxacin-based aquarium use. Always follow the Fix Flox label directions for dosing and handling.
What is Fix Flox used for in aquarium fish?
Fix Flox is commonly used to help manage bacterial concerns in ornamental fish, especially when signs suggest a stubborn issue such as fin breakdown, red streaking, ulcer-like sores, or septicemia-type involvement. For best control and monitoring, many keepers treat in a hospital or quarantine tank.
How does ciprofloxacin work?
Ciprofloxacin interferes with bacterial DNA replication, which can limit bacterial multiplication. It is commonly described as targeting enzymes such as DNA gyrase and topoisomerase IV.
Can Fix Flox treat fungal infections in fish?
Ciprofloxacin is an antibiotic intended for bacterial pathogens, not fungi. If you suspect a fungal problem, consider a product formulated for aquarium fungal issues and confirm the diagnosis when possible.
How do I dose Fix Flox for fish?
Follow the directions printed on your bottle. A common label approach is an extended bath using 1 dissolved dose per 10 gallons (38 L), repeated every 24 hours, with a partial water change between treatments, for 5 to 10 days. If no improvement is noted after 5 days, discontinue use per label and reassess.
Can I use Fix Flox in a display tank?
A separate hospital or quarantine tank is usually the better choice. Treating outside the main display can help protect invertebrates, reduce disruption to the biofilter, and make it easier to observe fish and control water quality during treatment.
Should I remove carbon or turn off UV during treatment?
Activated carbon and UV sterilizers can reduce medication levels in the water. Many hobbyists remove carbon and turn off UV during treatment, maintain strong aeration, and monitor ammonia and nitrite closely during the course.
Does Fix Flox affect beneficial bacteria or water quality?
Any antibiotic used in aquarium water can impact the system, especially if dosing is incorrect or the main display is treated. Watch for changes in water clarity, test ammonia and nitrite, and perform partial water changes as needed between treatments.
Is Fix Flox safe for sensitive fish species?
Sensitivity varies by species and by tank conditions. If you keep delicate or uncommon species, a hospital tank setup, careful observation, and guidance from an aquatic professional can help you choose the safest approach.
Can Fix Flox be used in saltwater tanks or reef setups?
Hobbyists do use ciprofloxacin in both freshwater and saltwater, but reef and invertebrate systems require extra caution. When possible, treat fish in a separate tank to reduce risk to shrimp, snails, corals, and other sensitive tank inhabitants.
Can I use Fix Flox alongside other medications or antibiotics?
Avoid combining antibiotics unless an aquatic or avian professional advises it. Mixing treatments can increase stress, complicate troubleshooting, and make it harder to judge what is helping.
How should I store Fix Flox capsules?
Keep the container tightly closed and store in a cool, dry place away from direct sunlight. Keep out of reach of children and pets.
Can Fix Flox be used for pet birds?
Ciprofloxacin for birds should be used only under avian veterinary guidance. Do not apply aquarium-bath directions to a bird. An avian veterinarian can determine whether ciprofloxacin is appropriate and set the correct mg-per-kg dose and duration.
What if my fish worsens or shows distress during treatment?
If fish show severe distress (gasping, loss of balance, rapid gill movement, lying on the bottom), stop treatment, improve aeration, perform a partial water change, and seek guidance from an aquatic professional. If there is no improvement after several days, follow the label direction to discontinue after 5 days and reassess.
