I have Whisper 5-15 gallon heaters, and I'm wondering if it's safe for them to be touching artificial plants and or the plastic walls of the Sterilite that my fishies' tanks will be sitting in. (the plant question is for in the spawning tank.)
thanks. I lost one of the black suction cups, so one of the heaters only has one. The very end of it, which is covered with with a black rubber "cage" is touching the side of the container because it is off balance. I'll have to try to fix that somehow.
