Wow.....Did you really bump your thread after it was only open for 42 minutes?
And Aquatik, Dovii are normally pretty skittish until they get a bit larger. I'm sure they'll come out of it. Mine really turned into a grade A #&$ hole banging on glass and attacking the algae scrubber at about 9".
And they'll likely color up once they're acclimated to their new home and grow a bit. Mine didn't really get great coloring until about the 8" mark, and now he's awesome. Give it time, good food, and good water quality, and I'm sure they'll be stunners.
As a side note, Dovii change colors. Mine goes from light blue to dark purple for the fins and head and the side changes colors as well, and he can vary from really colorful to washed out depending on mood (mostly), substrate, lighting, and if he knows he's going to be fed or not.
