My betta lives in a 1.5-gallon tank, which is a difficult size for which to find a reliable heater. I've been trying for the past eight months or so to find one that (a) would keep the water warm enough for the fish but (b) wouldn't boil the fish alive.

In my quest, I've tried two Marineland heaters. Neither one worked the way it was supposed to, and yes -- I DID follow the instructions, to the letter. These are the ones I tried:

1. The Marineland Shatterproof 10-Watt Mini Heater (http://www.amazon.com/gp/product/B00176DUEY/ref=oss_product) for tanks up to 3 gallons. This one barely kept the water at 74 degrees (even though it's supposedly factory preset for 78) and it only worked for a couple weeks. It quit, and I was back to wrapping a human's heating pad around the tank while I searched for a replacement.

2. The Shatterproof Mini Heater 10watt (http://www.amazon.com/MarineLand-SHATTERPROOF-MINI-HEATER-10WATT/dp/B0037PJMMC/ref=sr_1_4?ie=UTF8&qid=1286290350&sr=8-4), also for tanks up to 3 gallons. This one heated the water into the high 80s, even though it, too, was supposedly factory preset for 78. I don't know how much higher it would have gone, and I didn't dare leave it on overnight for fear I'd be facing a boiled fish in the morning. I yanked it out of the tank and went back to the heating pad.

Finally, I found the Elite Submersible Preset Mini Heater 25W - Elite A748. It's compact, it's unobtrusive, and it actually works as advertised. After a little fiddling with the adjustable control, my betta is now comfy and cozy at about 76 degrees. I don't have to worry about it boiling him overnight, and the tank stays warm even now that the nights are starting to get chilly and our house hovers at 69 degrees.

This little guy heats my 1 gallon tank to a toasty 80 degree's for my tropical female betta and shes THRIVING!!!! Lol. I'm planning to get a 2.5 gallon soon (piggy bank is slowly getting heavier), and i'm sure this little heater will do the job.

It was hard to find a heater small enough for my daughter's little 1 1/2 gallon tank that had an adjustable thermostat. We've had this one for a few weeks now and it seems to work perfectly.

Bought this to heat a 2.5 gallon aquarium. Heater easily attaches to the side of the aquarium and is fully submersible. There are no temperature markings on the heater as it is small and there is no room for a temperature display like the 50 watt and higher Elite non-mini heaters.

To properly adjust the heater, first submerge the heater in the aquarium and allow the heater to adjust to the aquarium temperature before plugging it. Allowing the heater to adjust to the temperature of the water will also give time to find out if there is a leak in the heater. Alternatively to check for leaks is to place the heater in a bucket of water for a few hours to see if it takes on water. Do not use a heater that leaks or is cracked or damaged, it will kill your fish and possibly you.

Adjust the heater to the lowest setting. Once the heater has adjusted to the aquarium temperature (and there are no leaks), plug it in and turn the knob to slowly increase the thermostat setting in the heater until the light comes on.

Allow the heater to heat until the light goes out, check the temperature with your aquarium thermometer and allow the heater to cycle on and off for a few hours. If the temperature is not high enough, turn the dial again until the heater turns back on (light will illuminate). Allow the heater to cycle on and off again for a few hours and check the temperature again. Repeat this until the desired temperature is reached.

This is a nice heater for smaller aquariums and I recommend it to others.

Heater arrived in good condition. Stuck it in the tank and plugged it in. Started making good heat right away. Bitty the fish went to Heaven a few short hours later.
This heater brought the temp in his tank from 66 to 82 rather quickly - too quickly. Works great, just be really careful with your small tanks. Bring temp up GRADUALLY, like over a few days. Fabulous heater - efficient cooker. R.I.P Bitty 2010-2011.

I heard a bubbly noise coming from the fish tank. I walked over and looked to see what it was and the heater had water in it. It then proceeded to explode in the fish tank. Thank You Hagen for trying to assassinate my turtles... They evaded your execution attempts once again..

I Unplugged it right as it was bursting so i dont know what kind of damage it would have caused. But the 2 hours seperating glass was a blast.

I have two bettas, one male and one female (both under 6 months old). Each of them has their own 2.5 gallon mini bow tank. I set up their tanks so the current of the filter is broken up, and unfortunately it didn't leave a whole lot of room for a heater. I tried the flat under gravel betta heater and it would just not fit, and I tried another one from walmart that said it was made for 2-10 gallon tanks, also did not fit. Finally after lots of searching I found this one and ordered two of them. I figured if the reviews say it works in a 1.5 gallon it'll fit in my 2.5 gallon tanks. My normally active fish were freezing (and lethargic) in 71 degree water and once I installed this, its amazing how much of a change it made!! Both of them swim non-stop now. The house is normally about 65-68 degrees so I have to turn the heat nearly all the way up to keep them between 78-80 degrees.

My male betta had a love hate relationship with it at first. He half-hung down from his betta leaf hammock and just started at it. Then he swam up, stuck his body against it and just sat there. He tried to bite it, squeezed behind it numerous times, smelled it, and eventually flared at it putting the intruder in its place. Now he's flat out having a love affair with it and so is my female. I catch her rubbing her body against it sometimes. It's hilarious how much they like this thing! It's also made them way more alert and active as well. Active = happy & healthy.

If you have a small tank, DEFINITELY recommend. It works, it has an adjustable knob to alter the temperature and the fish love it.
