Here's why:
* Tiger barbs are freshwater fish: They are naturally adapted to freshwater environments, and excessive salt can stress them.
* Salt is a temporary solution: It can help treat some infections but doesn't address the root cause.
* Potential side effects: Too much salt can damage gills, skin, and overall health.
When might a small amount of salt be used?
* Quarantine: Short-term use (a few days) in a quarantine tank for new fish to prevent parasites.
* Treatment: In very specific situations, such as fungal or bacterial infections, under the guidance of a veterinarian or experienced aquarist.
Instead of using salt, focus on:
* Maintaining good water quality: Regular water changes, proper filtration, and appropriate temperature are essential.
* Treating infections with proper medications: Consult with a vet or experienced fish keeper for specific treatments.
Remember: Always research the specific needs of your fish before adding anything to their water.
