Mini pre-set heaters are configured at 25 C° (77 °F) to ensure an ideal temperature in small aquariums. The new JOLLY PRESET is unbreakable thanks to a plastic shell. They are compact with minimum space
requirements, practical, precise, and reliable because the temperature is pre-set and regulated by an integrated circuit. Available in multiple wattages for multiple small aquarium
sizes, the JOLLY PRESET is an ideal heater for Betta fish, neons and amphibians.
