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.
Can i use a heat lamp for my betta fish.
Heat lamps are not as effective at maintaining proper temperature as an undertank heater uth.
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.
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.
Many betta lovers do not realize how important correct lighting is for the health of their fish.
Tanks that are smaller than 2 5 gallons can use submersible 7 5 watt heater pads.
A bubbler will do little else in a non planted tank aside from making protein scum build up less.
You would need to have it just the right distance away.
Changes in room temperature especially in buildings or climates that become much colder at night can prove stressful for a betta.
Ideally the water should be between 78 80 degrees fahrenheit 25 5 26 5 degrees celcius for a betta.
Not only do bettas need a consistent water temperature but they also need the proper lighting to set and keep their biological clock in a natural state.
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.
In short no you do not.
These pads don t regulate temperature so you will need to monitor the temperature of the tank often.
This environment keeps bettas happy and also determines their patterns for spawning and feeding.
It is also a great place to display your betta fish because they love being heated.
A heater for your betta fish bowl can be a life saver.
Plus it can also impact the humidity level.
This is a good alternative for people who do not have a lot of space to set up a heater.
