Review: Little beta blanket - This thing works like a charm! Just plug and play. Ever since I put it in my Fishtank, my little beta fish are so happy and warm. It’s automatically controlled by the thermostat set at the factory. I was a little freaked out at first when I thought of the idea of buying something that was controlled automatically, but no boiled fish yet! They’re warm and cozy and happy. If you’re on the fence about buying this for your beta fish, look no further than this heater. Buy your little beta fish a blanket before they freeze to death. I’ve been using it for about three months now and it’s held up so far. It’s the perfect size to fit into a 3 gallon aquarium.
Review: Perfect! - This is perfect for my 3 1/2 gallon beta tank! Keeps it the perfect temperature for him. His name is Gill.
