@Cthulukelele yes, @OrionN has been helpful for me as well. The fish I'm not certain about the sex right now I think might still have a chance to change to female if it is a male. I think it might be still in the juvenile stage.He is a fantastic resource and always happy to help. Idk the article you've read, but my understanding is in this species they gain 1 extra dorsal spine that is slightly more pronounced and grow significantly bigger. My cherub angel (very close relative) definitely transitioned from female to male while in my tank
