Aqueon Submersible Aquatic Flat Heater Mini Up to 2.5 Gallons, Black, 5 Watts

Thanks to Walmart for giving me a free month; it really helped me try to save my sick fish—though she is still ill, and I pray for her recovery. This heater is excellent; despite lacking a temperature indicator, it is a lifesaver for fish, especially in very cold homes. I recommend keeping the water level at a minimum of 4 liters to prevent overheating. Another important tip is to avoid covering the aquarium, as this can cause a sudden temperature spike. The heater works efficiently with 7.5-liter tanks. Be sure to follow the included instructions precisely: maintain the water level (refill the tank if water evaporates), do not touch the heater while it is plugged in, and do not remove it from the water before unplugging it. Handle electrical equipment in water with caution—this heater is designed for your safety and the safety of the aquatic life. Best of luck to everyone.

Literally the only product I will get for my 2.5 gallon betta tank

I love 💕 that I was able to find a small filter for my Betta to make his water 💦 comfy

This has been in our beta tank for about a week now. It keeps the water consistent between 78-80 degrees. It small which is great for our 2 gallon tank.

Very small size and seems to be heating without any issue. I would like to be able to see a light when it is on or something, but it is working, so no complaints. I am just glad it was small enough to fit inside my tank without taking up a lot of space. I have a 3 gallon betta tank.

It seems like a good product for the price.

i cant control the heat i am afraid of cooking my fish That's not funny

Over all good but I think got the water to hot and killed my beta

just too toyish

it DOES NOT WORK how do I get my money back
