Hi! I am somewhat new to the hobby. I have always had small tanks but nothing too "complicated." I just purchased a 45 gallon tank. Currently i just have rocks placed. My Molly and Betta are in another tank awaiting their new home. I have been told contradicting things in regards to the cycling period for this size - 1 week and 4 to 6 wks. What is the average time to cycle for a tank this size? How long must I wait between introducing new fish? Most importantly, what fish would you recommend? I was thinking 2 types of schooling fish but again, im a beginner!
