For sure the trailers that you see on the picture are a left are a giveaway. If the tail on the right is rounded then it is most likely a female, though that's a lot of fin color for a female. I've had some males though that took awhile to get the trailers and had a more yellow color, though this was in a tank with multiple other males. Might just have to watch for a little. I've had a 29 gallon with 2 females and a male that did just fine and had fry that I pulled. A fun fish to watch raise their young.

I agree with the silicone molds, I found a couple that are for water bottle ice cubes, think long and skinny. I mold my repashy in those and then slice off whatever length I need. I did make some using gummy bear molds, cute but too much work for me.
