Here is my f1 rio mag blue umbee. This umbee i had with a group of his siblings and was by far the most dominant and ended up killing the one i left with him/her and sold the rest since they were being pretty bullied. I am hoping this is a male but is hard to tell sometimes because i thought he would have more blue coloring in its body by now. It is pushing the 5" mark now. It's finnage is also starting to elongate which is also signs of a male. This fish also grew much faster than all the others which is another sign of a male so with all those things i am thinking and hoping i have a male. What do you all think? I have bright led lights on this tank so it makes the fish look a lot lighter like a female at times. i turned on my blue lights with a mixture of white lights at the end of the video to try and show more of his blue coloring.
