the difference a heater makes

I put a heater in my 1 gallon tetra halmoon tank and Balthazar is happier than he was without one. :)

what kind of heater did you put in there? What's the model number & wattage?

I have brought a Marina Betta 8w submersible heater which is perfect for 1-1.5 gallon tanks. It keep the water at 80 degrees. I no longer have the 1.5 gallon tank but on a whim I tried using it in my Aqueon mini bow 2.5 gallon tank and its works perfectly. It still keeps the temperature at 80 degrees. I liked it so much when I brought a second 2.5 gallon tank I brought another Marina Betta 8w heater. It's sell for 10.99 in PetSmart.
