If done right...yes. They never worked for me and always fell off or got twisted.What about the suction cups....wouldn't they keep the heater far enough away from the plastic walls?
My bad lol, in some ways I like it more, having right beside my computer chair I have a nice view anytime I look over, and as long as my filtration is keeping the water clear then I have no problem telling the fish from one another.Cool. I meant how do you like it. Viewing from above rather than the side? How well can you differentiate the fish?
