We bought a Juwel 60litre tank for our daughter about three weeks ago and all was fine for the first week or so, but then the temperature dropped from 26 to 19. We assumed it was the heater and got a new one sent to us, but that one doesn't seem to work either! We have them in a bucket now, and they are warm, but not hot. Do you know, should they be hot to the touch? And if they are not the problem, then what could it be?? I'm beginning to wish we'd never started this!
