No not really
No
If you betta is in a small tank, placing it in a location that has a warm ambient room temperature should be enough to keep it to betta preferred warmth. If you do not, then you should look at getting a small heater for your tank, but you may need to get a larger tank to allow for the use of a heater as there are no heater models made for anything smaller than a 2.5 to 5 gallon tank.
As big as you can get
Well, Yes and no. Betta do like LIGHT to be able to distinguish night and day, they also need the warmth, but you can use a heater. betta fish do need light, but it is not good to keep a betta in direct sunlight as it may increase the temperature byy far too much. so just keep it in light at day, or get a lamp.
yes but it would need a heater as they are both tropical fish and you would need to change the water alot.
It is best to invest in a heater. If your betta is in a small tank or bowl then a heater should be relatively inexpensive. Keeping the betta in a warm or heated environment is also a possibility. As an absolute last-ditch temporary fix, it is possible to place the betta's habitat on top of a heating pad. It is important to note that this CAN be dangerous. Heating pads have an associated risk of electrical fires and the potential of leaking water is dangerous.
If your tank is too small for a heater it's too small for the Betta. The answer is simple. Get a bigger tank. A male Betta needs a heater, a filter, a light and living plants to be healthy. It grows to about 2 inches long so that means it needs at least 2 gallons of water ie a 3 gallon max capacity tank.
It is unsafe to heat anything smaller than two gallons. As long as your room temperature is reasonable (68-76ish for a betta) you should have no problems. If not get at least a two gallon tank and heater, one with an internal thermometer unless you want to monitor it 24 hours a day.
Yes, a heater is recommended for Betta eggs to spawn, as they thrive in warm water. The ideal temperature for breeding Betta fish is between 78°F and 80°F (25°C to 27°C). Maintaining this temperature helps ensure proper development of the eggs and fry, promoting a successful breeding process. Additionally, stable water conditions contribute to the overall health of the fish.
For the best health and lifespan of a betta, you should consider something that is at least 2.5 to 5 gallons and can have a small heater (bettas need a water temp of 78F to 80F), and a low flowing filter on it whether that be a small internal filter, or a small HOB (Hang On Back).
Likely yes. Most sucker fish need a filter and heater though, and most betta's are housed without these things.
if you go to walmart you can get a tank, filter, food, water conditioner,and hood with light ,for 25$ and that's a 5 gallon tank and that's more than enough for a betta to live they really don't need a sponge or heater ive had mine for 3 years now and that's all i have
