how big is the BGK? despite them being sold as semi-aggressive fish, they are not, they quickly back down to other fish, and are only labeled as aggressive, because when they grow, will eat neons and smaller fish.
check out myinfo button, and see all the fish i keep with mine. because BGKs hide all day, any fish but african cichlids, and aggressive fish (pirannahs, oscars, puffers) i wont keep with them (ohh, and other electric fish, baby whales, elephant noses, other knives)
one fish i wouldn't get though would be a common pleco, as they systimatically hunt down and devour the bloodworms i feed my BGK
if you have any questions, feel free to PM me
