No, probably not. I have 4 pink squares that I purchased from Biota so they arrived all female no transition. Over the past year I've seen one start to transition and it has a very clear color difference. On the fish that is starting to transition to male you will see pronounced purple lines running along the body. The lower fins will also start to become more lavender or purple. The body will have a few blotches on its body for lack of a better word. It will look more or less the same as the others but the purple / lavender color will be brighter and more pronounced. How long it takes to go from this to the more traditional male we see I don't know - my first time seeing this happen.
Also you will start to see it head butt the other anthias, not nip at their fins. At least I have not witnessed this and none of my fish have torn fins, ever. It will dart down towards the substrate then turn and go vertical up to the others. Then it will dart really fast left to right. Basically it will be herding them with a bit of chasing to keep the hierarchy in check or harem. This also happens during feeding. In your earlier thread asking about this I noted that I feed hourly from 0830 to 1830 with two frozen mixes in between. Upon arrival it was clear that one was getting more attention than the others as it relates to their chasing which lead to less food it was getting. I saw its retreat area, I watched what food it preferred, and made sure to target feed the area it was at so it got food. Now it doesn't matter while it is still smaller than the others it manages to get food on its own without me paying attention.
For food I rotate through tdo x-small, small, medium, pe mysis, and hikari. Frozen I feed LRS reef, fish, nano, PE calanus, plankton, mysis, brine, and a few other cubes. The dry is mixed. The frozen I rotate through. All small portions. They arrived maybe 1 to 1 1/2 in size but now closer to 4 or 5" in total. Very active. Very aggressive at eating. Striking food with an intent to get everything they can. Very large mouths.
