I plan on adding 4 guppies to my 10 gallon tank with my 3 endlers. I can't get another tank, will this QT setup work? 3 gallon bucket Tetra Whisper Filter with air pump Tetra 25watt heater Simple hide and plant. Would this work? Do I have to cycle it if it is just for a week or two? How far up do I fill it? Sorry if these are silly questions, I've never done a QT tank.
