new baby bristlenose

I wouldn't really worry about it, they're shy by nature but they'll move when they feel the need. It might also be that he is slowly acclimating to his surroundings. I picked up a baby (size of an oto) albino lf bn about 2 weeks ago and for the first 3 or 4 days I didn't see him at all, the next couple days he could be sited occasionally, now he's right out in the open nomming on the diatoms that wickedly took over his tank.
 
I feel like mine act shy because their eyes are really sensitive to light. I'm not sure, but if the lights are on, they hide, and if they are off, they are all over the tank... not shy at all.
 
man my lil guy didnt eat his algae wafer that I hooked him up with. Instead he seems to prefer the crap thats on the glass. Thats like turning down a filet mignon for a white castle burger.
