Sedation in Goldfish

Fish · Carassius auratus · typical adult weight 0.01–3.00 kg

2 cited drugs treat Sedation in goldfish: Alfaxalone, Tricaine Methanesulfonate.

Pharmacologic sedation for diagnostic procedures, minor surgical interventions, and pre-anaesthetic premedi-cation. α2 agonists (dexmedetomidine, medetomidine), phenothiazines (acepromazine), and benzodiazepines (midazolam) form the backbone of veterinary protocols.

The overview above describes Sedation across species; the citations below are the ExoticRx dose rules scoped to goldfish — a reference list, not new species-specific clinical guidance.

Alfaxalone(Alfaxan)

Anesthetic
RouteDoseFrequencyDurationIndicationEvidenceSource
Immersion (bath)6 mg/L water (immersion bath)single immersion to effectContact time = immerse to the required plane. At 6 mg/L: sedation 5.89 +/- 0.40 min, light anaesthesia 13.79 +/- 1.04 min, surgical anaesthesia 19.75 +/- 1.84 min. Recovery times did not differ significantly between the three concentrations. The paper prints no maximum tolerated exposure time, so the endpoint is the anaesthetic plane, not a clock.Sedation and surgical anaesthesia for diagnostic handling and minor proceduresModerateLeonardi F, Costa GL, Interlandi CD, Rosa J, Ghidelli A, Musico M.
