Unless it is right under my nose.
They are fully submersible. I had an issue with that same heater, though. It worked fine for a day or two, then it just didn't keep the temp the way I wanted. It might help to simply let it sit in the tank for thirty minutes or so when you first get it so it adjusts to the tank's temp, and then plug it in. Since mine stopped working, I exchanged it for Penn-Plax Cascade Heat 25w (adjustable, about $16). (My fave local pet store swears by it, compared to Hydor.) I'm testing it out in a bucket of water, and it's working fine from what I can tell. Going to test it out for a few more days before I put it in my betta's tank. (It has an on and off light, and unlike Aqueon, you can leave it plugged in all the time.)
