Targeted treatment for internal bacterial infections in ornamental fish. Fast-acting, effective, and safe for sensitive species.
When to Use
Certain species of bacteria—such as Pseudomonas, Aeromonas, and Vibrio—can infect fish internally, often without early visible signs. These infections can lead to serious health issues if left untreated.
Use this treatment if fish display:
Lethargy or inactivity
Clamped fins
Loss of appetite
Red blotches or streaks on fins or under the body
Prompt treatment helps restore fish health and prevent the spread of infection.
How to Use
Calculate your aquarium volume in litres
(length × width × depth in cm) ÷ 1000
Or use our Dosage Calculator for quick help.
Shake the bottle thoroughly before each use.
Mix the required dose with 1 litre of aquarium water in a separate container.
Add slowly to the aquarium, distributing evenly.
This treatment can be repeated every other day, up to four applications if needed.
Advanced dosing:
If your aquarium water has a KH of 12 dKH or more and a pH of 7.5 or higher, the dose can be safely doubled for stronger infections.
Safe for Community and Sensitive Species
Anti-Internal Bacteria is designed to be safe for tropical, coldwater, and sensitive fish when used as instructed. Avoid using with invertebrates unless confirmed safe.
