I have a 5" thin bar datnoid that likes to hide in his pvc pipe almost all the time. I see him out sometimes after the lights are out but he never comes out with the lights on. He only feeds on shrimp every second day in the morning without the lights as well (he should be eating better). He has 2 motoro rays (about 12" each), a 8" HBRTG, 5 1" silver dollars and 2 3" pbass (which are picky eaters as well) for company in a 320g tank.
Is it normal for small dats to be this shy? Do they get braver when they get older or is there something I can do to make him more comfortable? There are no decorations in the tank besides the dats pvc pipe (8" long). He is light colored with dark stripes and looks stable but he doesn't act it.

. Ever since then he has been much more reclusive.
