Getting back to your original question jaws7777 -- cool as they are, I personally wouldn't call Datnoids very interactive fish, esp. when they're younger and more shy -- in a decorated tank they'll likely be hiding as much as swimming about, so it's possible your son might lose interest in a Dat after a bit, they're such slow growers it seems to take a lot of patience. I've had my Thinbar/NTT for about 6 months now -- just finally hitting a nice little growth spurt now, but he's still quite shy compared to most other fish I've had. krichardson has mentioned he'll likely get bolder as he gets bigger/older, which I'm sure is true, but again quite a bit of patience involved to where most Dats could be considered mildly interactive (and could never compare to say an Oscar or Flowerhorn in this regard). Just my 2 cents bro (and based on limited Datnoid ownership), not trying to totally turn him off about Dats, they really are awesome fish, just not what I would really call super interactive as bigger fish go.
Also the bigger ones I've seen at LFS (~18"-22") aren't shy at all, but they just float around chilling, and again don't seem particularly lively or interactive, impressive though they may be.
Btw, have you considered a Flagtail? Really cool fish, will clean the living daylights out of any tank and they have quite a bit more character than most Dats imho.
Actually my Dat and Flagtail are best buddies (the Dat uses the FT as kind of a big dither fish, makes him more confident to come out. Then he has the audacity to steal food from right in front of the the FT's mouth lol).
