What can the bartlett's do...............
As you would expect, the only potential issue is with one of the existing females not tolerating the intruder/new guest and converts to a male.
The only other consideration (not knowing your LFS) is that Bimac Males don't always transfer/ ship well and can be challenging during quarantine/ acclimation.
I honestly wouldn't do it. One of your females will eventually change.
Bimacs are awesome fish...probably my favorite Anthias.
A bit hard to see what is in the picture but bimacs, squas, Bartletts, hutchi, dispars and carberris where some species in the display. Overstocked for sure but it workedNice! Bimacs, lyretails ..... Bartletts? Male bimac has the 'I'm the boss' expression for sure.
