I started to get back into the hobby half a year ago and it is so addictive and fun that it keeps me really happy and excited every day. Initially I had a goldfish long time ago when I went to school and couldn't keep an aquarium for different reasons. Now I have a 5 gallon, 10 gallon and 20 gallon and I have plans to expand. There is so much to watch, build, plan and experiment which is just what I needed. I currently have two wonderful swordtails, three otocinclus and (way too) many gold-black mollies which have multiplied incredibly fast from just three molly fish. Some of them have already found a new home with fish keepers in our local aquarium club.
