I've never bought a fish that will get too big for the tank because I joined this forum months before I even got my first tank so I learned to research well beforehand.
I have however bought fish that are too small for a tank. This is because I have bought fish thinking they were big enough, got home, realised that they weren't as big as I thought they were and could get eaten or bullied or both, have to put them in a different tank to grow a bit.
