I'm going to be extremely boring and think outside the box on this one. I can safely say I don't own one single book on fish. I used to do way back in my fish keeping days of old.
Nowadays the only fish keeping books I need are these two little beauties pictured below. The black one has been with me since I returned to the hobby in 2015. It is full of all sorts of snippets of info regarding my tanks. The other one is a diary full of water change days and other important dates should my old fading memory fail me, lol.
