Treating a Goldfish with a Shredded Tail After Filter Entrapment

Injury Context

10‑year‑old comet stuck in filter by tail; tail shredded, large blood patch. Now in hospital tank with “damaged tissue” medicine. Fish off‑balance but alive. Babies spotted in pond.

Likely Cause

Post‑spawning weakness led to entrapment. Spawning near pump intakes is common.

Treatment Protocol

• Aquarium salt – 1 Tbsp/3 gal (supports osmoregulation).
• MelaFix – Natural antibacterial, promotes healing.
• Antibiotics – Maracyn (erythromycin) for internal infection prevention.

Prognosis

Fish heal remarkably; tail may not regain original shape but fish can return to pond after recovery. Main risks: infection and bullying (avoided in hospital tank).
