That is just too precious...I would have had heart failure and probably died myself. They are so full of surprises and so naughty at times... :
As far as I know they would be very injured if you had to remove them from a tight spot. The only and best way to prevent this is to follow a few short rules for tank decor:
When you purchase a decoration with entries into it for the fish to explore, make sure that there are more than one entry for them to go straight through or the size of the ornament needs to be at least 3" in diameter for the fish to be able to do a turn about inside so they can get out. The entry doors or windows (all of them) need to be large enough for the fish to go into with no problem. Tiny windows and little narrow doors will be a cause for alarm and probably a death trap. Also nothing made of Lava Rock should be used with a betta. It will snag fins and rip them.
Move all decorations away from the edges of any wall or other piece of decor by at least 1" to give them room to "swim through".
Heavily planted tanks should be planted with a good inch at least between the plant bases and more if it is a wide leafed plant. They go in and around plants and get tangled.
Hope this helps.
