Wow, so small! Yeah poly's can act kinda clumsy. Bumping into things is normal as they don't have that great of eye sight. Mine usually plows into any tank decorations at full speed whenever he gets spooked.
Cute little dude you got there AK!
at 1 inch, normally polys should grow into 2" to 3" in a month with adequate food. however albinos kinda grow slower. but who knows?! Good Luck!
