Good to see someone knows a little about Latin nomenclature, I can't believe how many people on this site miss-use the word "species".....
So you're saying P. bichir bichir isn't really an actual subspecies, and the second "bichir" is just added so people don't confuse it with P. bichir lapradei. IE It should really just be called P. bichir (not P. bichir bichir)?
