Expert Care Tips for Weather Loach
- Mid-size tank: Weather Loach needs 30+ gallons. Choose a tank at least 2× as long as the fish's adult size (10.0") for adequate swimming room.
- Cool-water species: Weather Loach tolerates temperatures as low as 50°F. In most homes, no heater is needed, but watch for summer overheating above 77°F.
- Adaptable pH range: Weather Loach accepts pH 6.0–8.0. Most tap water falls within this range, but always test and acclimate slowly.
- Peaceful community fish: Weather Loach works well in community tanks. Still, avoid housing with fish large enough to eat them — a 10.0" fish is vulnerable to anything with a mouth bigger than 2×.
- Acclimation: Always drip-acclimate Weather Loach over 30–45 minutes. Match temperature and pH gradually to prevent osmotic shock.
