NeoPlex

  • Broad spectrum antibiotic effective against most external infections
  • Safe for marine and freshwater
  • Minimal impact on bio-filter

NeoPlex™ is a broad spectrum antibiotic effective against most external infections of both marine and freshwater fish. Used as directed, NeoPlex™ will not discolor the water or damage the filter bed. It is well tolerated by invertebrates, although delicate species may be stressed.

Active ingredients: neomycin sulfate (43%) Inactive ingredients: excipients (57%)

NeoPlex™ is appropriate for treating a variety of external infections of both marine and freshwater fish. Below are some of the more common diseases treatable with NeoPlex™. Be aware that many diseases and infections share similar physical and behavioral symptoms, e.g. clamped fins, lesions, loss of appetite.

fin rot
Bacterial infection

Fins appear shredded, frayed, or decaying. Fin Rot is frequently mistaken for damage from fin-nipping fish. Contrary to the name, this is actually caused by bacteria, not fungus.

Suggested Treatment Period:

7 days or until infection clears

Special Considerations

Fin Rot is often found as a secondary infection (that’s an infection that started because the fish was already sick). Make sure to check for additional infections.

baterial lesions
Bacterial Infection

Open wounds or sores on the body or tail of the fish. Bacterial lesions appear on the body or tail of the fish. They often look like an open wound, sore, or deterioration of the skin and flesh of the fish.

Suggested Treatment Period:

Dose in the water 3 weeks

Special Considerations

Bacterial lesions often start due to wounds on the fish, either from travel or from residence in a tank of aggressive fish. Using an antiseptic like StressGuard™ will help to prevent this.

bloat
Symptom of internal infection

Fish’s belly appears swollen and may have trouble swimming. If the scales stick out, this is called Dropsy and is better treated with KanaPlex™. Bloat is often caused by intestinal infections, but can also be a symptom of internal parasites or damage to the fish’s liver.

Suggested Treatment Period:

3 weeks or until fungus clears

Special Considerations

Bloat is a relatively common and easily treated condition in fish. If left alone, though, it can eventually develop into Dropsy, which is much more difficult to treat. NeoPlex™ is very effective against bacterial infections of the intestines, but if the infection spreads to other parts of the body, we recommend treating with KanaPlex™.

mouth rot
Columnaris

Damaged fins, ulcers and yellowish patches on gills, tissue on head and mouth eaten away. This infection appears gruesome, but is entirely treatable. It is common to see fungus-like tufts around the face and mouth in addition to deterioration of tissue. It is essential to catch this disease early to prevent long-term damage.

Suggested Treatment Period:

1 week

Special Considerations

Columnaris is very contagious. If possible, remove the infected fish to treat separately in a hospital tank.

Dosing in Water

Remove all invertebrates - these are extremely sensitive to medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon™ and Purigen®. Use 1 measure (included) per every 8 L (2 US gallons). Repeat this dose every 7 days to a maximum of 3 weeks. This will treat external bacterial infections.

Dosing in Food

Feed the medicated food mix every day until the infection clears or up to 1 week. This will treat internal bacterial infections. This medicated food can be refrigerated or frozen between feedings.

  • 1 scoop NeoPlex™
  • 1 scoop Focus™
  • 1 tbsp food (preferably pellets or frozen food)
  • A few drops of water if using a dry food

To enhance palatability use with GarlicGuard™ or Entice™.

After Treating

When the treatment period is over, NeoPlex™ can easily be removed using activated filter carbon like MatrixCarbon™. It does not linger in the substrate or filter media of the tank. Remove with carbon before turning on UV.

A: NeoPlex™ is safe with most invertebrate life but a better application would be to use our Focus (nitrofurantoin based binding agent) to adhere NeoPlex™ to frozen food and feed it to your fish. Using it in this manner ensures that little if any medication will make its way in your water column.
