I tried a trio of what I thought were 2 females and one noticeable male with elongated dorsal. they were ok in qt except the submissive one never really ate.
after a few weeks in qt..I put in display 75g and all hell broke out shortly after. I was think the dominant female was starting to change over and wnt to battle with the male over a period of several days, it ended up getting killed, the one that didn't eat ended up dying and the male eventually died as well. not sure why. sucked big time ..fish are stunning for sure and really wanted it to work out.. due to the price not likely to try again any time soon.. I was also told that once they start to transform they cannot change direction.. turning male cannot revert back to full female.. don't know.
good luck
