Your Crystal Red Shrimp Vet-Prep Sheet
Finfern honest freshwater care · finfern.com 🔍 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.
🚨 Is this an emergency now?
Act promptly — starting with a water test — if you notice any of these:
- Shrimp dying off after a water change, a new dose of anything, or a temperature swing — the source warns "sudden fluctuations can quickly prove fatal"; check for instability and copper exposure.
- Any detectable ammonia or nitrite, or rising nitrate — CRS are "extremely sensitive"; test and correct the water immediately.
- Failed molts, shrimp stuck half-out of the old shell, or no breeding despite mature adults — usually a sign water parameters (gH/kH/TDS/pH) are off; recheck against the target ranges. (A shrimp simply hiding for a day around a molt every 3–4 weeks is normal.)
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
- 16.5–24.5 °C / 62–76 °F (The Shrimp Farm)
- pH
- 5.8–7.4 (The Shrimp Farm)
- Hardness
- gH 4–6, kH 0–4, TDS 100–200 (soft, low-mineral — The Shrimp Farm)
- Minimum tank
- ~19 L / 5 US gal can sustain a colony; ~38 L / 10 US gal is easier for beginners (The Shrimp Farm)
- Filtration & flow
- Gentle sponge filter; stable soft acidic water; NO copper (lethal); cycled tank only
- Diet
- Omnivore/grazer — algae and aufwuchs plus a quality shrimp food and occasional blanched veg
- Tankmates / temperament
- Peaceful and vulnerable — best in a shrimp-only or shrimp-plus-snails tank
⚕️ 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?
