Something I always find interesting is seeing the species from both angles. What they are like in the aquarium trade, conditions kept in, foods fed, reproduction etc, and how that compares to their cousins in the wild. Example, livebearers. What you see for sale at your lfs is often quite different from what you'd find in the wild. I always find it so interesting to see really where these fish come from, what their natural environment would be like if they were actually wild fish rather than the tank raised variety, etc. Makes one appreciate their fish a bit more when they know "where that fish comes from" so to speak......... Know what I'm saying?
And even though you may not be an expert now, this is your chance to really dig in and do some extensive research, and become somewhat more of an expert. Should be an interesting experience for you.
