I agree Krich. Bold colored dats just seem to know they look pretty and they seem to cruise the tank much more than unstable ones...OP..If your new to dats, I recommend just enjoying and learning your new dats. Indos are a tough, inexpensive dat species and a great species to get some familiarity with dats. If the color really concerns you now.. the problem many times gets worse as he grows, but again I recommend keeping them and forget about stability for a while
