A little experiment.

i think it looks good almost like a picture you'd hang on a wall at your house
 
I like the background if you are getting a pic for ID or to look for details. If it is just for viewing enjoyment, I prefer whatever background is normally there.
 
looks good - reminds me of the way the pics in Cichlids The Pictorial Guide are taken (by the Tepoots)
