Treating Tetras with eSHa Exit: Curing White Spot in Sensitive Schools
Tetras are the "canaries in the coal mine" of the aquarium world. Species like the Rummynose Tetra will show physical signs of stress (losing their red face) at the slightest chemical shift. When White Spot (Ich) strikes a school, it can wipe out 20+ fish in a matter of days if the treatment is too harsh.
eSHa Exit is the gold standard for tetras because it avoids the harsh copper found in many legacy Ich treatments, making it safe for even the most sensitive schooling fish.
White Spot vs. Velvet in Tetras
Tetras are susceptible to two main "spot" parasites: **Ich** (Ichthyophthirius), which looks like grains of salt, and **Velvet** (Piscinoodinium), which looks like a fine gold or yellow dust. Most medications only treat one. eSHa Exit treats both, which is vital because Velvet is often deadlier to small fish like tetras.
Safe for Planted Tanks?
Most tetras are kept in beautiful planted setups. Unlike malachite green-heavy treatments that can stain your silicone and melt your plants, eSHa Exit is **plant-safe** at standard dosages. You don't have to choose between your fish and your Aquascape.
Calculated for Your School
Precision is everything for small fish. Use our eSHa Exit calculator to find the exact drop count for your Net Water Volume, ensuring you kill the parasite without stressing the tetras.

- Carbon removal: If you use "Crystal Clear" or carbon media in your filter, take it out. It will remove the medication before it can kill the Ich.
- Oxygenation: Schooling fish have high metabolic rates. All medications can slightly lower oxygen. **Ensure strong surface agitation** or add an air stone during the 3-day treatment.
- Finish the course: Even if the spots disappear on Day 1, you must finish all 3 days. The Ich parasite is only vulnerable to medicine when it "bursts" from the fish—finishing the course ensures you catch the whole cycle.
Can I use eSHa 2000 with Tetras?
Yes. In fact, if your Cardinals or Neons look "pale" or have fuzzy patches along with the spots, we recommend the **Exit + 2000 combo**. It treats the parasite and the secondary bacterial infections simultaneously.
Conclusion
Don't gamble with harsh Ich treatments that might "cure" the disease but kill the fish. eSHa Exit is the professional’s choice for sensitive tropical fish. Be precise with your volume, finish the 3-day course, and keep that water oxygenated.
