I'm also curious, since I have a pair now, if they always trend to male resulting in a transition or if some live their full lives as females. @jkcoral how long have you had your pair?
They are too cute to think of as deadly murder beasts!
I added the small female to my male back in April, so 8 or 9 months they’ve been together. So far I’ve not seen any indications of her transitioning, and no changes in behavior, she’s always tied to his hip or somewhere close by. I was interested in the opportunity to watch and learn from their little dynamic over time given the relative lack of knowledge about these little guys. Maybe now that she’s beefed up and healthy, a transition could come, or maybe they are just more likely to stay in that pair dynamic than other wrasse. It be interesting to see.
I’ve also really wanted to watch and learn about group dynamics of possum wrasses. But my possum went full warlord on the other and had almost killed it in less than 48 hours and I had to move it to my dad. I don’t know if it’s just because my possum turned out to be a gangster or not, but I’d like to try again some day.
