Pacu was someone who liked to start useless threads to get people all riled up...people were getting mad at him on the other boards, so he tried moving to cephs...he's now "moved on". You should search his threads...they're amusing...kinda.
Well, I at least learned something from this thread. I knew the two species that "bimac" stood for, but I didn't know that bimaculatus was the less common. I was kind of curious - if I purchased a bimac, how would I know which one I got? Now it seems like it most likely won't be a bimaculatus.
Bimaculatus is a deeper water species. It is harder for the collectors to catch them. They can be ID by the broken chain in their ocellus.Bimaculoides has a unbroken chain. The arms on bimaculatus are also longer. The other fact that seperates the two is their egg size. Bimaculatus lays small eggs and bimaculoides lay large eggs that hatch into benthic young. Bimaculatus grows to be about twice the size of bimaculoides.
