Tank tips for Chennai homes
- No heater for most fish; watch for overheating above 31°C in May-June.
- Aeration matters more than heating in Chennai's warmth.
- Cyclone season: keep a battery air pump for long power cuts.
- Water source: if you use tanker or bore water, test hardness and pH before using it for soft-water fish.
Fish that fit Chennai's climate
Warm-water fish such as guppies, mollies, bettas, gouramis and tiger barbs. Goldfish need a cooler room or a fan.
Bringing fish home: the first 24 hours
- Float the bag in your tank for 15-20 minutes so the water temperature evens out.
- Mix tank water into the bag a little at a time over another 15-20 minutes.
- Net the fish into the tank and throw the bag water away instead of pouring it in.
- Keep the lights off for a few hours and do not feed on the first day.
