Why a secure lid is recommended for betta tanks and what to consider with airflow and equipment.
A betta tank should usually have a secure lid because bettas can jump. Leave room for equipment and normal air exchange, but do not keep the tank wide open.
Even calm bettas may jump during feeding, stress, or exploration. A lid protects against accidents.
Choose a lid that works with the heater cord, filter, and light. Cover large gaps when possible.
Bettas breathe at the surface, so the lid should not seal the tank airtight. Normal aquarium lids allow enough air exchange.
