Choose an accessible home
Use a fish-safe container without a chemical-use history. Place it on a stable support you can easily reach. Watch how sunlight moves across it during the day. Avoid crowding a small volume of water.
A practical kit
Have a thermometer, water conditioner, water tests, a dedicated clean bucket, siphon and net. A filter should provide gentle flow with a fry-safe intake. Size equipment for the actual water volume.
Clear water is not proof of readiness
Remove harmful disinfectants using a suitable product as directed. A newly fitted filter is not a mature biological filter. Establish and test the system before adding fish; do not use a crowded stocking as a readiness test.
Introducing the fish
Avoid transferring fish abruptly between different water conditions. Acclimate with attention to transport conditions, then watch breathing and balance. Prepare a separate observation container before introducing newcomers to an established group.
