🔍 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.
- Refusing food and hiding for days, or a hollow belly (small fish fade fast — act early).
- 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
- Tiny — about 1–2 in (3–5 cm).
- Lifespan
- About 2–6 years, depending on care.
- Minimum tank
- 10 gallons and up — genuinely nano-friendly; 30+ is more forgiving. Give it branching coral or rockwork to perch in.
- 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
- Loves branching coral (or rock) to perch and hide in; keep nitrate low.
- Diet
- Carnivore with a tiny mouth — small meaty foods: gut-loaded brine shrimp, mysis, cyclops. Often wants small or live foods at first, then weans onto frozen. Feed small amounts often.
- Temperament
- Peaceful and timid — a poor competitor for food, so pair it with gentle tankmates. Fine in a small group in a big tank, but keep a single or pair in a nano (they squabble with their own kind in tight space).
- Reef-safe
- Mostly — with a caveat: it may nip the polyps of the SPS/Acropora it lives in (feeding on mucus; spawning can nip polyps too). Damage is usually minor and corals recover, but SPS keepers should know.
- Natural range
- Indo-Pacific — lives among the branches of living Acropora.
⚕️ 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?
