Black Tiger Badis aka Dario sp. 'Myanmar' protecting its cave

This is one of 10 Tiger Badis in this 130G community tank along with tetras, shrimps and otos.
In this video it can be seen protecting its cave among the roots of the Anubias Galabra on left side of the wood. Hoping there are some eggs/fry in there that has made him to territorial.
By far the most interesting fish to watch in the tank.
