Can Aquarium Heater Burn Fish. Like we just established usually an aquarium heater is remarkable cool to the touch. Although its not common for heaters to cause burns on fish or damage tank décor it is possible if the contact is prolonged.
An aquarium heater can overheat and explode the glass tube that let many heater elements out and can catch any flammable things to start a fire. The main risk for heater burn wounds are secondary infections. Aquariums where there is an excess accumulation of gaseous release are also likely to burst if the gas gets agitated by the heat from the tanks heater.
Depending on the fish these can become stuck between the glass and the heater or if the heater is in a horizontal position they decide it is an excellent place to sleep.
An effective heater for your betta fish bowl is a very important accessory for keeping them healthy and happy. Other fish like oscars have even been known to attack aquarium heaters. Your fish wont be able to get to that. I run 9 heaters in different tanks and never had a fish burn themselves on them but not to say it does not happen.
