The fin has been like that for the 2/3 hours or so I had it, it has never been fully extended, that's why I'm confused as well. I'm wondering if it is somehow a mix gender or a gender-less fish or something like thatMissNoodle said:emeraldking ? Shape looks more platy than molly, especially with the dorsal fin but im not familiar with this colouring in either so... i could be wrong.
But i cant tell the gender with the fin like that. Sometimes females can appear to have a pointed fin like males when folded, so i cant say for certain from these photos myself.
