I need a little help. I am such a newbie to the fish world. My daughter got a tiny dime sized fish she called Maggie. It killed the other fish twice it's size so it became my fish. This thing is a monster five years later. I bought a 75 gallon tank and rinsed the rocks, bought two Penguin 300 filters and now have to fill it. My issue is Maggie is at least a foot long and I am not sure how to transfer her into the new tank. I almost killed her when I went from a 10 gallon to 30 gallon. I knew nothing about fish. I know I have to let the water sit for awhile but how long? I have water tester but I really don't understand the whole cycle thing. Lol... I know, I know !!! Here is my other problem... The 30 gallon tank is leaking somewhere and I have to move her pretty quick. I have well water that I use for my 20% changes and Maggie loved the new water. My well water usually tests perfect for her. A nice high PH and the temperature is all I need to worry about. How should I move Maggie? Should I use a bucket? A plastic bag and let her acclimate? Should I try to save as much water from the 30 gallon to use in the 75 gallon? Ugh... I am so scared I will kill her! Help!
