Aquarium Advice Addict
I was just at Walmart and found a Junior Heater brand aquarium heater for 2-5 gallon tanks on sale for $5.00, so I picked one up. My question is this.....how do you go about putting a heater in a tank with a fish already in it? This is for my small 2 gallon tank that my betta is in now, until my 10 gallon has finished cycling for him. Will it gradually heat up giving him time to adjust or do I take him out, heat up the tank and then float him in it for a time?
