🔍 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.

🚨 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.
- Hiding and refusing food 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 3–4 in (7.5–10 cm).
- Minimum tank
- ~30–55 gallons with plenty of live rock to forage through and hide in.
- Temperature
- 72–78°F (22–26°C).
- pH
- 8.1–8.4.
- Specific gravity
- 1.023–1.026.
- Other targets
- Lots of rockwork to hunt through and sleep in; keep nitrate low.
- Diet
- Carnivore — frozen mysis, brine and krill plus small marine preparations, 2–3× a day. It also hunts pests (pyramidellid “clam-parasite” snails, flatworms, bristleworms, pods) — but this varies a lot: some are voracious pest-hunters, others ignore pests once used to easy frozen food.
- Temperament
- Peaceful as a juvenile, but develops a real semi-aggressive, territorial streak with age — it harasses newcomers and fish of similar shape. Keep ONE per tank, and add it LAST, after the calmer fish are settled.
- Reef-safe
- Reef-safe with corals — but not fully invert-safe: it can pick at ornamental crabs, small starfish, clams, and desirable pods/small shrimp.
- Natural range
- Indo-West Pacific and the Red Sea.
⚕️ 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?
