Hi,when i first got my 2.5 gallon tank and a betta in the summer, the temp was around 78 most of the time, but now its starting to drop with the weather changing, is there any way i can keep the tank warmer untill i can get a small heater at the weekend?
If it's only until the weekend you could wrap a towel round it at night. Day time temps in the average house with central heating will be fairly reasonable but a heater will keep the tank at a constant temp so its good that you're getting one.
