A bubbler will do little else in a non planted tank aside from making protein scum build up less.
Can i use a heat lamp for my betta fish.
Lamps are not the best choice for heating as betta fish do not like bright lighting.
Many betta lovers do not realize how important correct lighting is for the health of their fish.
Ideally the water should be between 78 80 degrees fahrenheit 25 5 26 5 degrees celcius for a betta.
Yes you can use a desk lamp as long a sit cant get splashed but usually the bulbs are the wrong wave length of light usually causing serious algae issues just keep that in mind.
Changes in room temperature especially in buildings or climates that become much colder at night can prove stressful for a betta.
Your best option is to buy a uth that is one size smaller than recommended for your aquarium i have a 20 gallon tank and i bought a uth for a 10 gallon and place it under the dry side of the tank opposite the water dishes and not in the middle of.
However a filter so long as it isn t too strong and won t knock the fish around or rips fins allows a tank to cycle as well as not need 100 water changes.
You would need to have it just the right distance away.
This environment keeps bettas happy and also determines their patterns for spawning and feeding.
A heater for your betta fish bowl can be a life saver.
Tanks that are smaller than 2 5 gallons can use submersible 7 5 watt heater pads.
Plus it can also impact the humidity level.
Heat lamps are not as effective at maintaining proper temperature as an undertank heater uth.
I have actually used a desk lamp as a heat source for my brine shrimp hatchery jars but i would never rely on it for a fish.
This is a good alternative for people who do not have a lot of space to set up a heater.
It is also a great place to display your betta fish because they love being heated.
In short no you do not.
1 because bettas are often kept in very small tanks or bowls heating can be a challenge.
