Great prise !
Nah, shouldn't be a issue. Bichirs will eat almost everything but it can take some time (couple of days) for it 2 become hungry enough 2 start eating other stuff if its not interested at the begining.
What are u planning 2 feed it with? Make sure 2 use Pellets, its the best
Good price, although I am can almost guarantee it's not 16 inches. My guess is either that they're exaggerating the size, or that's it not a del at all. Could be an endli, I've seen people confuse the two.
