🔍 Find an aquatic vet

  • Search the WAVMA (World Aquatic Veterinary Medical Association) directory — or search "aquatic / exotics vet near me".
  • Call ahead: "Do you treat marine fish?" Few vets do — find and save one now, while things are calm.
  • Ask the exam fee when you call — knowing the cost up front removes the money-panic in a crisis.

What I'm seeing

🚨 Is this an emergency now?

Quarantine and get help promptly if you notice any of these:

  • White salt-grain spots, flashing, or rapid gill-breathing (possible ich or velvet).
  • Cloudy skin patches, clamped fins, or gasping at the surface.
  • Refusing even an evening feed for days, or a hollow belly.
  • Any new fish added without quarantine.

🚗 On the way / while you wait

✅ Do

  • Test your water NOW — salinity, ammonia, nitrite, nitrate, alkalinity and temperature — and correct anything obviously off.
  • Move the fish to a hospital / quarantine tank if you have one.
  • Keep it in its own stable tank water.
  • Keep the tank calm and dim.

⛔ Don't

  • Don't dose the display tank with OTC or shop “cures” blindly — copper and many meds are harmful to inverts and corals, and they mask the real cause.
  • Don't make a big, sudden parameter swing.
  • Don't add anything you can't explain the reason for.

🎒 What to bring

  • A recent, full water test — salinity, alkalinity, nitrate, temperature (and ammonia/nitrite/pH if you have them).
  • Photos plus a short video of what you’re seeing — it may not show it in the clinic.
  • A note of your system and how you feed.
  • Only if advised: the animal itself, in its own tank water.

🗣️ What to tell the vet / expert

Adult size
About 3 in (8 cm).
Lifespan
About 2–5 years.
Minimum tank
20 gallons for a small group; 30+ is better for a proper shoal.
Temperature
75–82°F (24–28°C).
pH
8.1–8.4.
Specific gravity
1.020–1.026 (≈35 ppt; keep it stable).
Other targets
Calm, low–moderate flow; keep nitrate low.
Diet
Not picky — flake, pellet, frozen mysis and brine shrimp, live blackworms. It's a nocturnal/crepuscular feeder, so an evening feed suits it best.
Temperament
Peaceful and slow-moving — and genuinely social: keep a group (odd numbers, at least 3, ideally 5+). Singles or pairs aren't recommended.
Reef-safe
Yes — definitely reef-safe; it leaves coral polyps and clam mantles alone.
Natural range
Western Pacific and parts of the Indian Ocean (Australia, Fiji, Japan).

⚕️ Most marine illness starts with water quality or acclimation, not infection — bring a full set of parameters (salinity, alkalinity, nitrate, temperature). Marine-fish medicine is specialised and few vets treat fish, so call ahead. Copper and many OTC 'cures' are toxic to invertebrates and corals — never dose them in a reef display; treat a sick fish in a separate quarantine/hospital tank, and tell the vet exactly what you've already added.

❓ Questions to ask

  • Do you treat marine fish?
  • What are the likely causes — and could my water or acclimation be the cause?
  • What is the treatment plan, the likely cost, and what should I watch for?
  • How do I prevent this happening again?
