For ornamental aquarium fish only.
Three 100-count bottles, three antibiotic classes: the medicine cabinet for fish rooms, breeders and big tanks.
If you run more than one tank, a 30-count bottle is gone before the course is finished. This pack puts three full 100-count bottles in one box, each from a different antibiotic class, so the right tool is already on the shelf the day an outbreak starts. Fish Flox 500mg (ciprofloxacin) hits the gram-negative bacteria behind septicemia, fin rot and popeye; Fish Penicillin 500mg covers gram-positive and strep-type infections; Fish Sulfa 960mg (SMZ/TMP) is the classic answer to columnaris and body slime. Three classes, no overlapping actives, and enough tablets to carry a whole rack of tanks through a complete course. Built for fish rooms, breeders, grow-out systems and anyone who is tired of reordering mid-treatment, and it is the biggest saving in our range at $34.98 off buying the bottles separately.
What's in the pack (3 bottles):
- Fish Flox 500mg, 100 tablets (sold separately at $109.99)
- Fish Penicillin 500mg, 100 tablets (sold separately at $99.99)
- Fish Sulfa 960mg, 100 tablets (sold separately at $69.99)
Use it for:
- Whole fish-room or multi-tank outbreaks that need repeat dosing across several aquariums
- Large community, grow-out and show tanks where a 30-count bottle runs out mid-course
- Gram-negative infections: septicemia, red streaks, fin rot and popeye (ciprofloxacin)
- Gram-positive and strep-type infections: lethargy, spinning, hemorrhages (penicillin)
- Columnaris, mouth rot and body slime spreading through a group of fish (sulfa/trimethoprim)
Why buy the pack:
- Save $34.98 versus buying the 3 bottles separately ($279.97)
- Everything ships together in one box
- Full-size retail bottles, the same products sold individually on this site
- Sealed bottles with a long shelf life, so the pack keeps until you need it

Intended use & safety
Intended use & safety
This product is sold for use with ornamental aquarium fish only. It is not for human use, not for use in animals raised for food, and not intended for dogs, cats, livestock or any other animal.
Nothing on this page is medical or veterinary advice, and we cannot recommend doses for any animal. If a pet needs treatment, consult a licensed veterinarian who can examine the animal and prescribe appropriately.
Keep out of reach of children and pets. Store in the original sealed container in a cool, dry place away from direct sunlight. Check the lot number and expiry date printed on the packaging before use.
Antibacterial treatments can reduce the nitrifying bacteria that drive your tank's nitrogen cycle. Many aquarists treat in a separate hospital tank, monitor ammonia and nitrite during a course, and plan extra water changes afterwards.
