Your Scissortail Rasbora Vet-Prep Sheet
Finfern honest freshwater care · finfern.com Scissortail Rasbora — 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.
🚨 Is this an emergency now?
Act promptly — starting with a water test — if you notice any of these:
- Fish gasping at the surface, hanging near the filter outflow, or unusually lethargic - stop feeding, test the water immediately (ammonia, nitrite, nitrate) and do a water change; gasping often means an ammonia/nitrite spike or low oxygen.
- The whole shoal clamping fins, going pale, hiding, or dashing/glancing off objects - a stress or water-quality/parameter-swing signal; check temperature, test parameters, and review recent changes rather than assuming disease.
- A fish found on the floor or repeatedly leaping - your lid is not sealing; close every gap around cords and filters at once.
- White spots (like grains of salt), fuzzy patches, rapid gill movement, or persistent flicking/scratching - possible signs of common illness like ich; isolate/observe, keep water pristine, and seek advice from a qualified aquatic vet or a trusted fishkeeping source. This is triage, not a diagnosis.
- Sudden loss of appetite in a normally eager eater, or a fish hanging apart from the shoal - treat it as an early warning: test the water first, then watch closely.
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 (72-79 F). SeriouslyFish gives 22-25 C; most keeper guides sit around 23-26 C. Aim for a stable point in the low-to-mid 20s C rather than chasing the extremes.
- pH
- Around 6.5-7.5 is ideal (roughly neutral, leaning slightly acidic; ~6.6 is often cited as a sweet spot). The species tolerates a wider 5.0-8.0 depending on wild origin, but a stable value in the ideal band beats a "perfect" number that swings.
- Hardness
- Soft to moderately soft: GH about 2-12 dGH. They adapt to a fair range, but genuinely soft, slightly acidic water shows them at their best.
- Minimum tank
- Keeper-facing minimum for a proper shoal is about 114 L (30 US gal). You will see 75 L (20 gal) quoted, and a small young group can start there, but the honest bigger-is-better reality is that these are strong, restless swimmers: SeriouslyFish recommends a 120 x 45 cm (48 x 18 in) footprint for adults, roughly 240 L (64 gal). Swimming LENGTH matters far more than raw volume - a long 90-120 cm tank beats a tall one every time.
- Filtration & flow
- Gentle-to-moderate flow suits them well - a filter that turns the surface over and hints at a gentle stream current is ideal (a light powerhead is fine in a long tank). Keep them well filtered on a fully cycled tank; they are active and need clean, oxygenated water, but you do not need whitewater.
- Diet
- Omnivore leaning micro-predator. In the wild they eat small invertebrates and insects; in the tank they readily take quality flake or micro-pellet as a staple, best supplemented with small frozen/live foods.
- Tankmates / temperament
- Genuinely peaceful and non-aggressive - not a fin-nipper. The catch is energy: they are fast, busy, near-constant swimmers, so their activity can unsettle slow or long-finned tankmates even though they never intend harm.
⚕️ 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?
