blocked nostril

[Dev_Man]

I was looking at my BP yesterday evening and notice one of his nostrild seems to be blocked by what looks like a small pebble like thing...is there anyway i could remove it?and what could it be?

thanks for the help

well, first make sure that it is a foreign object before you try to remove it. could it be your substrate? if you have a loose substrate, this could be the problem. bps are skittish about their heads, so it might be difficult to get it out. is it affecting his breathing?
