🔍 Find a reptile / exotics vet — before you need one

  • Search the ARAV Find-a-Vet directory (the Association of Reptilian & Amphibian Veterinarians), or in the UK the RCVS Find-a-Vet — or search "reptile / exotics vet near me".
  • Call ahead and ask the key question: "Do you see reptiles?" Not every practice does.
  • Ask the exam fee when you call. Knowing the cost up front removes the money-panic in a crisis.
  • Find and save one now, while things are calm — not in the middle of an emergency.

📇 Fill this in now — before the crisis

Two minutes now saves ten in a panic. Print it and keep it with your care notes.

What I'm seeing

🚨 Is this an emergency now?

See a reptile vet promptly if you notice any of these:

  • Swollen, puffy, or shut eyes, or a runny nose, whistling, or open-mouth breathing — possible respiratory infection or vitamin-A issue; see an exotics vet.
  • Soft, spongy, or pyramided shell, or a beak that won't stop growing — signs of poor calcium/UVB and metabolic bone disease.
  • White, red, pitted, foul-smelling, or flaking patches on the shell or skin — possible shell rot or fungal/bacterial infection.
  • Refusing food for more than a week or two once settled, sudden lethargy, or floating lopsided/unable to dive evenly — get it checked.
  • Basking constantly and never entering the water, or staying underwater and never basking — a behavior change worth a vet call once husbandry is ruled out.

When in doubt, a vet call is never wrong — most issues are reversible if caught early.

🚗 On the way / while you wait

✅ Do

  • Keep it warm at a safe transport temperature — a cold reptile crashes fast (a warm car or a covered container with a warm, not hot, pack helps).
  • Keep it calm, dark and quiet in a secure, ventilated container — stress makes almost everything worse.
  • Bring it in its own container so the vet sees it as it lives.

⛔ Don't

  • Don’t offer food, or any OTC, aquarium-shop or online-forum remedy — many are useless or harmful and can mask the signs.
  • Don’t let it get cold on the way in.
  • Don’t handle it more than you must.

🎒 What to bring

  • A short video and a couple of clear photos of the behaviour or sign — it may not show it in the clinic.
  • A note of your setup (basking, cool-side and night temperatures, UVB, humidity, substrate) and exactly what — and how often — you feed.
  • A recent water-test result — water quality is a direct cause of shell, skin and eye problems in aquatic reptiles, and a good vet will ask about it.
  • Your reptile, transported safely in its own secure, ventilated container — kept warm (see below), not in a cold car.

🗣️ What to tell the vet

A general vet may not know this species. Come ready to explain its correct care:

Temperature
A completely dry basking dock (floating platform, cork slab, or above-water ledge) they can climb fully out onto and drip-dry. Map turtles are "aggressive baskers", so make it easy to reach and stable. Basking-surface temperature ~95–100°F (35–38°C), up to ~110°F at the hottest point for large adults (per Austin's Turtle Page), always with a cool side to move to. Lights and basking heat off at night is fine. Room temperature down to the mid-60s°F (around 18°C) is acceptable as long as the water stays in range; if the room gets cold, the water heater keeps the tank stable overnight.
Water temperature
72-76°F (22-24°C) for adults and sub-adults; hatchlings and small juveniles do better a bit warmer at 78-80°F (26-27°C). A submersible aquarium heater (guarded so the turtle can't crack or burn on it) holds it steady.
Water depth
As deep as you can give them — map turtles are powerful, confident swimmers who thrive in deep, open water. Hatchlings start shallower at about 4-6 in with plenty of easy resting spots and structure to climb, then go progressively deeper as they grow. Always provide submerged rest ledges so they can pause without a hard swim to the surface.
UVB & lighting
Real UVB is non-negotiable. Use a linear T5 HO tube — Zoo Med ReptiSun T5 HO 5.0 or Arcadia Forest 6% — running the length of the basking end (about 50-75% of the tank length). Like the closely related slider (Ferguson Zone 3), aim for a UV Index of about 3.0-4.0 on the dry basking surface. Mount a 5.0/6% tube roughly 11-13 in (28-33 cm) above the platform (a 10.0/12% tube goes higher, 17-21 in), never closer than 10 in, and never behind glass or fine mesh — glass blocks ~95% of UVB and mesh ~30%. Replace the tube every 12 months even if it still glows.
Enclosure
Think in swimming volume, not floor space. A single male needs a 75-gallon tank minimum; a single female needs a 125-gallon tank minimum (Austin's Turtle Page). A common rule of thumb is at least 10 US gallons of water per inch of adult shell length. Bigger is always better for these active swimmers — hatchlings can start in a 20-gallon long, but plan for the adult tank from day one.
Substrate
Bare bottom is easiest to keep clean and is perfectly fine. If you want a planted, natural look, use sand or river rock/gravel that's either too large to swallow or fine enough to pass — avoid the small-to-medium gravel a turtle could gulp and impact on.
Diet
Predominantly carnivorous, and mollusc-loving in particular. In the wild females crush snails, clams, and crayfish with their broad jaws while males take aquatic insects and smaller snails. In captivity, base the diet on a quality aquatic-turtle pellet (Mazuri, ReptoMin) plus whole prey — snails, earthworms, crayfish, krill, and the occasional feeder — with some leafy aquatic greens and plants offered too. Feed hatchlings daily; taper adults to protein 2-3x per week with more plant matter, to avoid overfeeding and shell/growth problems.
Supplements
Offer a cuttlebone or calcium block floating in the tank at all times — they'll gnaw it and it buffers the water. With proper UVB, extra vitamin-D3 dusting usually isn't needed; only supplement D3 if you cannot provide good UVB (which isn't recommended). Snails and other whole, shelled prey are also a natural calcium source.

⚕️ Reptiles are ectotherms kept at species-specific temperatures — a cold reptile can’t metabolise medicines properly, so tell the vet your exact temperatures and keep it warm for transport. Reptiles are prey animals and hide illness until it is advanced, so early changes matter. Mention your UVB/lighting and any supplements or remedies you’ve already used, and ask for reptile-safe products and doses.

Then note which of the warning signs (above) you are seeing, when they started, and whether they are getting worse.

❓ Questions to ask

  • Do you routinely see reptiles? If not, can you refer me to a vet who does?
  • What are the likely causes — and could my setup or diet be contributing?
  • What is the treatment plan, the likely cost, and what should I watch for at home?
  • How do I prevent this from happening again?
