What this site is
Happy Lucky Fish Club publishes a hobbyist reference for freshwater keepers (goldfish-heavy, with notes where tropicals differ). Content is synthesized from product labels, published textbooks and hobby manuals, and experienced keepers’ protocols.
What this site is not
- Not a veterinary diagnosis, prescription, or treatment plan for your fish.
- Not a substitute for an aquatic veterinarian, diagnostic lab, or current product label.
- Not a promise that any protocol will work for every species, age, or water chemistry.
- Not a place for folk remedies. We do not recommend floating garlic, “energy” cures, or superstitions like “floating food makes fish float.” Floating after dry floating pellets is usually gulped air / constipation / other listed causes — see the floating card.
Salt: use a kitchen scale
Teaspoon measures of aquarium salt vary with crystal size. Weigh salt. Teaspoons are a last resort when you have no scale.
- True supportive 0.1% ≈ 1 ppt = 1000 ppm ≈ 3.8 g per US gallon (~¾ tsp only if your salt is ~5 g/tsp).
- The hobby line “1 tsp/gal ≈ 0.1%” overshoots (~0.13–0.15%). This site follows the mass-based table.
- Never confuse ppm and ppt (
1 ppt = 1000 ppm). A target of 0.1% is not 0.1 ppm.
Full cheat sheet: Treatments → Salinity.
When to escalate
- Multiple deaths after corrected water and a completed, appropriate course
- Chronic wasting / clean scrapes / mycobacteria on the differential (zoonotic caution; gloves; no reliable OTC cure)
- Need for injectables, culture/sensitivity, or necropsy
- Prescription / restricted drugs in your jurisdiction
- Unsure of species-specific salt or heat tolerance (scaleless fish, some koi lines, etc.)
Gaps & honesty
- Named products on this site (Quick Cure, Romet-type foods, Dimilin, injectables, etc.) may be unavailable, renamed, restricted, or vet-only. Prefer current labels + vet guidance.
- Heat protocols (~84–86°F) and harsh oxidizers (e.g. potassium permanganate) are high-risk; parasites first; oxygenate heavily.
- Formalin + malachite green products: toxic, oxygen-robbing; never mix with PP.
- This site is goldfish-centric. Do not copy goldfish salt/heat ceilings onto every tropical.
- Re-check before treating: verify against current labels and vet guidance.
