Your aquarium does need a heater and I’m surprised you have gone this long without one. Guppies are tropical fish and the water temperatures need to be in the mid 70s at minimum. I imagine your fish are starting to be put under stress from it. Guppy fish call out for tropical water conditions of 70-78 degrees Fahrenheit. If your tank isn’t within that range constantly… then you need a heater. I’m trying to hold back on being mean, but you need to better research your pets before you just dump them into a habitat. Your fish could easily die from a variable like this that you neglected to follow. When buying an aquarium heater, figure on 5 watts per every gallon of water in your tank. So.. you said your tank is 10 gallons, that means the heater needs to be 50 watts. Local fish stores overprice heaters so I suggest buying online. Here is a .The total electric cost of running a 10 gallon aquarium per month, as estimated above, is $1.92 dollars, $23.04 annually, for a 10 gallon freshwater fish tank with no live plants, or $3.08 dollars, $36.96 annually, for a 10 gallon saltwater fish tank supporting live plants or coral. This tank size is cheapest and great for people with a small budget. The 10 gallon tank size is also the most inexpensive to setup, as less strong lights and heaters cost less than stronger counterparts. The Aquatop Quartz 50 watt comes in at 8.5" x 1.25". The heat will run consistently 2 degrees warmer than it is set to, making it reliable when properly set. By using a second thermometer you can easily find the right setting for your tank.

The main yet minor issue the Aquatop has is setting the heat. The dial on top of the heater is difficult to turn, especially when wet. However once it is set correctly you don't need to worry about the settings being changed on accident.

The light/heating element on the Aquatop comes on for one minute intervals to ensure the water is not heated too quickly. This is a key feature many heaters miss when it comes to heating 10 gallon fish tanks.

One of the bigger draw backs this low cost 10 gallon aquarium heater has is the fragile design. While the glass is shatter resistant it is nowhere near shatter proof. Take caution when moving the heater around rocks or to the sink for cleaning. Holding the cord when walking to the sink was how I cracked my first heater. One glass 10 gallon aquarium;
