Jumpingspider identification

[Mathijsd]

Hi all!

I just found myself a tiny jumpingspider (my best guess is the Heliophanus aeneus) and I would love to know a bit more about it (actual spiecie, gender, feeding habbits,...). He is about 3mm in length and I found him sunning on a metal plate next to the long grass. If possible, I would love to keep it for a while to observe it's behavior and shoot some clips.
Much appreciated!

Generic jumping spider should be fine. Fairly dry, food half the size of the body, potentially something for it to web to (sticks, bark, etc.).
