🔥Description🔥

With an adjustable thermostat range from 18°C to 32°C (64°F–89°F), automatic on/off operation, and a light indicator, it maintains consistent water temperature for tropical fish and planted tanks. The slim 21 × 2 × 2 cm form factor fits neatly inside most aquariums and mounts securely using the included suction cups.
