Fish vets are rare, and it is easy to freeze in a crisis. This is the one page to have ready — how to find a vet, what to bring, what to tell them, and the questions to ask. Print it and keep it by the tank.

Black & white saves ink and prints cleanly on any printer.

Not sure it's a vet trip yet? Run the symptom checker or the water-parameter interpreter first — many worries turn out to be a water or husbandry fix.

Salt and Pepper Cory — Vet-Prep Sheet

🔍 Find an aquatic / fish vet — before you need one

  • Search the WAVMA aquatic-vet finder (the World Aquatic Veterinary Medical Association) — or search "aquatic / fish / exotics vet near me".
  • Call ahead and ask the key question: "Do you treat fish?" Few vets do — and ask the exam fee while you're on the phone.
  • Find and save one now, while things are calm — not in the middle of a crisis.

📇 Fill this in now — before the crisis

Two minutes now saves ten in a panic. Print it and keep it by the tank.

What I'm seeing

🚨 Is this an emergency now?

Act promptly — starting with a water test — if you notice any of these:

  • Barbels look short, eroded or stubby, or the fish stop rooting in the sand - usually a sign of sharp/dirty substrate or poor water; check the sand and test/change the water, and seek advice if it worsens.
  • Fish sit still, hide constantly, or 'clamp' their fins and lose their busy foraging behaviour - a stress signal. Check that the group is at least 6, test the water, and review temperature and flow.
  • Rapid or laboured gilling, gasping, or repeated dashing to the surface as a group beyond the odd normal air-gulp - test the water immediately for ammonia/nitrite and do a water change; persistent gasping means act, don't wait.
  • White spots, fuzzy patches, red streaks, ulcers, or a bloated/pinecone look - isolate/observe, test and correct water first, and consult a fish-savvy vet or trusted aquatics store rather than guessing at treatments.
  • A new addition looks thin, pale or lethargic - quarantine new fish where possible; a sunken belly often means it was underfed and needs targeted sinking food.

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

🚗 On the way / while you wait

✅ Do

  • Test your water NOW — ammonia, nitrite, nitrate, pH and temperature — and correct the obvious (a big source of trouble is ammonia / nitrite).
  • Keep the fish in its own stable, dechlorinated tank water.
  • Move it to a hospital / quarantine tank if you already have one set up.
  • Keep the tank calm and dimly lit — stress makes almost everything worse.

⛔ Don’t

  • Don’t tip in OTC, aquarium-shop or forum “cures” blindly — many are harmful or just mask the real problem.
  • Don’t make a big sudden water change or swing the parameters.
  • Don’t add salt or medication without knowing the cause.

🎒 What to bring

  • A recent water-test result — ammonia, nitrite, nitrate, pH and temperature. Water quality is the root of most fish illness and the first thing a fish vet asks about.
  • Clear photos and a short video — it may not show the behaviour or symptom in the clinic.
  • A note of your setup and exactly what — and how often — you feed.
  • Only if the vet advises transporting the fish: the fish in a bag or tub of its OWN tank water.

🗣️ What to tell the vet

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

Temperature
22-26 C (about 72-79 F). They tolerate down to ~20 C (68 F), but keep them warm and stable - they are a tropical species and need a heater in most homes.
pH
6.0-7.5 is the safe, comfortable range (they are reported as low as 5.5 and up to ~7.5). Aim for stable neutral-to-slightly-acidic rather than chasing an exact number.
Hardness
Soft to moderately soft: GH roughly 2-10 dGH. They do best in softer water and are not a hard-water/high-mineral fish.
Minimum tank
Keeper-facing minimum is a tank with a base footprint of at least 60 x 30 cm (24 x 12 in) - that works out to roughly 54 L / ~14 US gal. In practice a standard "10-gallon long" (~40 L) is the smallest most keepers use for a starter group of 6, but the honest, bigger-is-better reality is that a longer 20-gallon-long-style footprint (~75 L / 20 US gal) lets you keep the 8-10+ group they actually want and gives them room to forage as a shoal. Swimming/foraging LENGTH matters far more than raw litres for a bottom-dwelling cory.
Filtration & flow
Gentle to gentle-moderate flow. In the wild they live where water movement is weak (lagoons, slow tributaries), so avoid a strong current - baffle a powerful filter or aim it at the glass. They still need a properly sized, cycled filter for water quality; "gentle" means flow, not skimping on filtration.
Diet
Foraging omnivore (scavenger of the bottom, not a "clean-up crew" that lives on leftovers).
Tankmates / temperament
Peaceful, gregarious and busy. A classic non-aggressive community bottom-dweller that spends its day sifting the substrate in a little group.

⚕️ Most fish illness starts with water quality, not infection — bring a recent water test; it's the first thing a good fish vet will ask about. Fish medicine is specialised and few vets treat fish, so call ahead. Many aquarium-shop and OTC 'cures' are harmful or simply mask the real problem, so tell the vet exactly what (if anything) you’ve already added, and treat a sick fish in a separate hospital tank rather than dosing the whole display.

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