The Dats seem to be fine, their stripes come and go as usual.. alteast with 4 of my 6 Indos. Two are always good, the others some days are better than others. Depends on their moods
I generally dislike fake plants as well but with some fish you don't have much of a choice. You might be able to use some java fern or moss attached to the driftwood as filler though. That might help tie it all together. Just a thought...
