What are your favorite "sleeper" fish?

Diamond Tetra's are my favorite. They were not really that great looking in the store, but I had seen some nice pictures on the internet. I have 6 in my 55 gallon and they are beautiful. They look like someone sprinkled glitter all over them. They are constantly on the move and are one of the larger tetras so quite eye catching.
 
Yeah rainbows are definately sleepers. People don't realize they are a beautiful, active fish with colour and intelligence at the LFS o.o

it takes a week or so to get'em coloured up and happy =)

When was the last time you saw a male in full display colours at the LFS?

As for me the answer would be uhmm "never" lol :joke:

The ones I bought showed great colors in just one day. But they seem to be getting brighter as the days went by.
