🔍 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:
- Fish gasping at the surface, hanging in the filter outflow, or lethargic can signal too little oxygen or flow — increase surface agitation/turnover and test the water.
- One fish hiding constantly, clamped, or with nipped fins in a small group means the group size is wrong — you likely have too few; move to a single fish or increase to 5-6+ and add cover.
- Any ammonia or nitrite reading above 0 ppm, or a sudden loss of appetite, means test the water now and do a water change — this species does not tolerate an immature or dirty tank.
- Rapid colour fading or persistent dark blotching can indicate stress (aggression, poor water, or wrong temperature); check parameters, flow and tankmates before assuming illness.
- White spots, cottony patches, rapid gilling, or a fish sitting listless on the bottom are triage signs — isolate if needed, test water, and seek advice from a fish vet or an experienced fishkeeping community rather than guessing at treatments.
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
- 22-27 °C (72-81 °F). They sit comfortably in the typical community-tropical band of about 22-26 °C; they come from cool, oxygen-rich hill streams, so avoid the warm end of tropical for long stretches.
- pH
- 6.5-7.5 (neutral, slightly soft to slightly hard is fine).
- Hardness
- Soft to moderately hard: GH about 2-12 dGH. They are not fussy about hardness as long as it is stable and the water is clean and well-oxygenated.
- Minimum tank
- Keeper-facing minimum around 80-90 L (about 20-24 US gal) on a footprint of at least 90 x 30 cm (36 x 12 in). Reality: swimming LENGTH and flow matter more than volume here — for a settled group of 5-6+ a 90-120 cm long tank (roughly 120 L / 30+ US gal) is much kinder, because these are stream fish that dart and graze across open, current-swept surfaces.
- Filtration & flow
- Wants brisk, well-oxygenated water — this is the single biggest key to success. Aim for turnover comfortably in excess of 10x tank volume per hour; a canister with a spray bar and/or an added powerhead creates the linear stream flow and high oxygen it evolved for. Provide smooth rocks and driftwood for grazing surfaces and current breaks.
- Diet
- Omnivore and, above all, a biofilm/aufwuchs and algae grazer. It rasps the film off rocks, wood and glass, and also takes small meaty foods and quality sinking vegetable-based foods.
- Tankmates / temperament
- Peaceful toward unrelated tankmates but genuinely spiky toward its own kind and similar-shaped fish — expect a pecking order with charging and fin-flaring, not gentle schooling.
⚕️ 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?
