All recommendationsComplete shopping list
Adjustable 50W Aquarium Heater
Bettas need stable tropical temperatures; an adjustable heater is safer than relying on room temperature.
Aquarium Sponge Filter
The safest filter style for shrimp fry and long-finned bettas because it provides biological filtration without a hard intake.
Filter Intake Pre-Filter Sponge
A cheap safeguard that prevents shrimp fry from entering hang-on-back filters and softens intake pull.
Digital Aquarium Thermometer
A separate thermometer catches heater drift before livestock are stressed.
API Freshwater Master Test Kit
Ammonia, nitrite, nitrate, and pH tests prevent the most expensive beginner mistake: adding livestock to an unsafe tank.

Can a betta live in a 5 gallon tank?
Yes, if the tank is heated, filtered, cycled, and maintained.
Should I buy fish the same day as the tank?
No. Set up and cycle the tank first so ammonia and nitrite are safe.
