90% P. lapradei
10% chance for P. bichir
The difference is very hard to tell, when they are so small.
According to recent publications, P. lapradei (former P.bichir lapradei) is no subspecies of P. bichir anymore.
A good indicator is the country of origin, as P. lapradei is spread more in the western areas of africa, P. bichir rather in central africa.
