Betta White Patches & Goldfish Lumps: Salt, Diagnosis & Treatment

Betta: Not Ich, Likely Fungal/Bacterial

White patches on tail/fins (not body) suggest Columnaris (cotton wool disease) or fungal infection—not Ich (which appears as salt-like speckles on body). Salt is not curative here.

Betta Treatment

1. Quarantine in 1–2 gal heated tank (78–80°F), cycled filter.
2. Antibiotic: Kanaplex (kanamycin) or Furan-2 (nitrofurazone) — follow label.
3. Indian Almond Leaves or StressGuard for slime coat support.
4. Salt only as mild preventative (0.5 tsp/gal), not primary treatment.

Pond Salt vs. Aquarium Salt

Both are sodium chloride. Check labels: Pond salt may contain yellow prussiate of soda (anti-caking) — safe at pond doses but unnecessary. Pure aquarium salt or non-iodized kosher salt works fine.

Comet Goldfish Lumps

Lumps on a single fish in cool water (60°F) with healthy tankmates suggest:

• Benign tumors (common in older goldfish) — no treatment.
• Carp pox (viral) — waxy, resolves with warmth.
• Abscess — if red/inflamed, may need antibiotic injection (vet).

Do not medicate the pond for one fish. Isolate if worsening. Most lumps are cosmetic.
