The question, Do Betta fish need a heater , is fairly common.
Yes, they need a heater. Betta fish need a temperature of 78-82°F which is ideal for them.A temperature of 76-82°F is good
too.The biggest effect is temperature fluctuations, being too low or too high.The temperature below 74°F or above 85°F affects the health of the betta.
Cool environment is the best for the betta fish although majority of them will fail to survive in such climate. This is the reason as to why the heater will be needed to avoid fish sickness. This heater is also useful in case you do not have a heater installed. Bettas and any type of fish are usually sensitive to tank temperature and constant temperature fluctuations
You can do without a heater if only the water in the tank is at a constant temperature. Heaters are sold at fairly affordable prices. They are very important because they help to keep the betta healthy. If the temperature is too cold, that is, temperature below 74°F,it causes distress to your fish which may cause them to die.
As soon as temperature of the water in the tank begins to drop, automatically your fish becomes sluggish. A fall in temperature results in a slow down of metabolism as the fish tries to regain energy. Cold temperature also induce stress for in the betta fish making them unable to feed.Once the fish can not eat,the immune system weakens adding them more stress.
To identify if the temperature has fallen,the betta will try to stay deep below the tank in an effort to seek heat. The colour of the betta too begins to fade right from the skin to the scales.
In cold temperature,the betta can also succumb to a disease known as dropsy.
For the fish living in too hot temperature
Too hot temperature may rise up to 84°F or 85°F.This kind of heat will eventually cause the betta to overheat.
The fish lives in cold environment simply because they are cold-blooded. Erratical swimming of the fish shows that the temperature is abnormal or too high.Extra heat weakens the immune system of the fish.
To reduce or prevent the water temperature, having a fan at the top of the tank is viable.The fan helps to evaporate excess heat keeping the tank cold.
