I have recently acquired a 75 gallon tank from a friend who gave it to me as a moving away gift and i was wondering what would be the easiest build with the least possible maintenance I have a pretty then budget of around 200 bucks for filters and other items,Also i was wondering about cycling and what it is.I am also looking more into the smaller fish with a couple of schools in the tank if you get what i mean,with maybe one or 2 3 inch fish.
