Avoid Direct Sunlight
Sunlight causes relentless algae blooms.
Temperature swings of 5°C+ through the day stress fish.
Position at least 1 meter from any window.
Stable Stand

Use a dedicated aquarium stand or a solid hardwood furniture rated well beyond tank weight.
Floor must be level and rigid.
Electrical Access
GFCI outlet within 1 meter, with drip loops on all cables.
Avoid extension cords and power strips on high humidity lines.
Low Traffic
High foot traffic stresses shy species.
Keep away from doors and hallways.

Water change siphon run to a drain or large bucket station.
