  • Beta tank
Size: 25W
This was a good find for a small tank. I have been using it for a month now and it keeps the tank at the perfect temperature for our beta.

  • it works
Size: 25W
I appreciate how simple this is and that it requires no configuration at all. The temperature is kept pretty consistent in my 6 gallon tank. I would prefer a temperature setting for different fish that may have different preferences, but this does work well for the Betta fish I am keeping.

  • Great for small tanks
Size: 25W
This is great for my betas small tank! I could tell a difference immediately, he seemed happier and swimming around. Only complaint is the cord is a little short but overall perfect buy.

  • good affordable buy
Size: 25W
I recently purchased the Pamaner 25W Small Aquarium Heater for my mini fish tank, and I must say, I'm impressed! This heater is compact yet powerful, providing consistent and reliable heating for my aquatic friends. I love that it comes with a preset temperature of 78℉, which is perfect for tropical fish species. Installation was a breeze, and the heater quickly reached the desired temperature without any fuss. The compact size is great for smaller tanks, and the sleek design blends in seamlessly with my aquarium setup. Overall, I'm very satisfied with this mini fish tank heater from Pamaner and would highly recommend it to fellow fish enthusiasts! ... show more

  • Runs hot, closer to 82 F
Size: 25W
I am an Amazon Vine reviewer, and I chose this item, which I received for free, in return for an HONEST review. (I do pay taxes on all Vine products.) I am reviewing the 25W small aquarium heater preset to 78F sold by the pamaner store. I chose this heater for my 10 gallon aquarium. I have guppies in there and 78F is a pretty ideal temperature for them. I like that this heater is compact and didn’t take up a lot of room in the aquarium. Since I didn’t have a similar size bucket to test this heater, I went ahead and placed it in the aquarium early in the morning, so I could keep a close eye on the temperature of the tank. After about 4 hours, the temperature of the tank had increased from 78F, which is what I had the old thermometer set at, to 82F. I had to take this thermometer out because 82 F is just too hot for guppies. I checked the temperature with the analog thermometer in my aquarium, as well as two separate digital thermometers that have been calibrated. Unfortunately, this is a no go for me. If I had fish that liked warmer water, like a Betta, this might be a good fit, but for tropical fish, it just made the water too warm. This is the last time I try a thermometer that isn’t adjustable. I am not able to recommend this product, as it was about 4 degrees hotter than the preset temperature. I might be able to use it in my greenhouse to produce warm humidity for my plants, but that’s about it. I hope this review helped and happy shopping! ... show more
