🔍 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:
- Deflated, mouth gaping, or “insides” coming out — a stressed or dying anemone; test water immediately and be ready to remove it before it fouls the tank.
- Constant wandering and never settling — usually light or flow it doesn't like, or unstable water; a roaming anemone is also at risk in pumps.
- Shrinking, losing colour or turning translucent (bleaching) — light, feeding or water-stability problem.
- Detaching and tumbling in the flow — check it hasn't drifted toward a powerhead, and stabilise conditions.
🚗 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
- Typically 4–8 in across in aquaria (up to ≈12 in).
- Lifespan
- Very long-lived — effectively indefinite in a stable, well-fed tank; it can outlast the aquarium itself.
- Minimum tank
- A mature, established tank (≥6 months). A single BTA suits many reef tanks; allow 75+ gallons for multiples.
- Lighting
- Strong reef lighting — roughly 250–350 PAR. Bright light drives the bubble-tip shape and colour.
- Water flow
- Moderate — enough to bring it food, but avoid a direct powerhead stream that can tear it.
- Placement
- It chooses its own spot. Expect it to wander for the first weeks until it settles its foot into a rock crevice; give it open rock and space away from corals.
- Temperature
- 75–82°F (24–28°C) — stability is critical; rapid swings stress it badly.
- pH
- 8.1–8.4.
- Specific gravity
- 1.023–1.026 (reef-standard ≈35 ppt).
- Feeding
- Photosynthetic (via zooxanthellae) PLUS meaty foods 2–3× a week — mysis, chopped silversides or anemone pellets. Feeding drives growth and splitting.
- Growth & spread
- Splits (asexual reproduction) into more anemones when it's healthy and well-fed — one BTA can become several over time.
- Temperament
- A mobile, stinging animal — it can sting neighbouring corals and catch small fish. Give it room.
- Reef-safe
- With caution — it stings and it moves; site it with space from corals and screen your pumps.
- Natural range
- Indo-Pacific.
⚕️ 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?
