Features
- Beep Alarm, Fault Prompt: Our nano aquarium heater has safety features such as low water level shutdown and overheat protection. When the temp control system detects a malfunction in the equipment, it will give an error code alarm and stop heating to prevent any potential damage or injury. Note: Although the system will automatically turn off the power when a malfunction occurs, residual heat in the heating rod may melt the shell. Please handle it as soon as possible
- Black Look & Mini Size to Hide Easily: The 75-watt Betta heater with a 4" long x 1" high heating element design takes up very little space, which could effortlessly fit into 10-15 gallon small aquariums and is also suited for shallow water turtle tanks
- Adjustable Temperature Control: hygger mini submersible heater includes an external thermostatic temperature controller, you can easily set the temperature by cycling between 59 and 93 degrees, and the digital display makes for intuitive viewing of real-time water temperature. Once the heater is on, an indicator light will tell you whether it is in heating mode or on standby
- Intelligent Automated Heating: This small fish tank heater effectively maintains the water at a steady temperature, when it reaches below your set temp, it kicks on and then turns off when it reaches the desired temp. Also, with the memory function, you don't have to reset the temperature if you get power outages
- Safety Instruction: Please keep the heating rod fully submerged, use the two suction cups to make it easily installed vertically or horizontally on the tank wall. Make sure to unplug before water change or cleaning, cool down the water heater for 15 minutes

It got the tank up to temp quickly. It's easy to adjust the temperature. It's accurate to what the other tank thermometer displays. It's pretty small so it doesn't take up much space. It seems to be staying in place well with the suction cups.

I found a 3 gallon fish tank that someone threw out. After setting it up and deciding on a betta, I realized the room temperature wasn't going to be warm enough. The tank is as long as a 10 gallon, but only 7 inches tall. When I saw this little heater with the name Hygger, my search ended. I briefly skimmed over the details and pressed "add to cart". This was easy to set the temperature and the suction cups are doing the job. Only after installation did I realize it comes with a built-in thermometer! This is perfection for my needs.

This works really well for my betta! I haven't had any issues with it. I wish I knew it existed sooner! Very cool! Extremely adjustable and keeps him comfortable year-round in my drafty room and lets me know with the light everything's good.

Works well, temp seems to be within a few degrees of thermometer. The audible low water alarm is nice. only thing I don't like is how bulky it look in a 3.5 gallon tank (not the heaters fault). All around a great heater.

Best EVER heater for aquariums. I have tried 5 different brands, this being the fifth one. Call me crazy, but I'm extremely paranoid when it comes to my pets. I've read horror stories about heaters breaking, zapping fish, or overheating and cooking fish. Any time a heater has any kind of temperature issues or temperature control issues, I throw it in a box and return it. I don't play when it comes to my creatures' safety. I had three heaters, two of which were brand new, that we're heating to higher temperatures than I was setting. In addition, they would constantly turn on and off before reaching the desired temperature, taking a long time to heat up. I would have to adjust these heaters constantly depending on my room temperature, but not with this one. This heater heats quickly and doesn't burn you or any fish. I've previously touched my heaters before in the tank while they were running and got scorched. Imagine if a small fish touched that. Oh no!!! While you can buy a plastic heater guard for these traditional heaters, they cost $15-25 for each guard. Yikes! That's as much as the heater itself! This one has a plastic guard built-in with it's design already. Genius. I can touch the heater without being burned and so now I'm sure my fish and snails will not be burned. It also has a remote to make it easy to adjust the temperature without putting your hand in the water. I do notice the thermostat reads 2 degrees lower than my regular tank thermostat, so I set the water to 76F degrees and it achieves a consistent heating of 78F degrees for the tank. Although this is a minor inconvenience, the pros far outweigh the cons. Every day it's kept the tank at a consistent temperature and I don't feel scared to constantly check the temperature like how my other heaters had me checking. Love LOVE this heater and will be buying the 100w and 200w versions for my 20 gallon and 30 gallon tanks. My 50w heater here pictured is in my 10 gallon Betta tank.

I use this in a mini cube tank for my Betta. Works very well so far. holds tank at a steady 78f degrees . Kicks on and off with no issues. Seems like pretty good quality so far, fingers crossed it holds up for a long time.

Great.. easy to set, easy to use... clearly says temp of water and when it's on or idling... really like that it has digital temp that is so easy to read compared to most tank thermometers.. would definitely buy this again
