Your more than welcome
I think though that your tank is too small for both of your paradise fish, it's wise to have at least 11 litres of space for just your male. The plants and rocks take up more space but you need these. The male is going to feel very cramped and will continue to bully.
If you wanted to keep a community tank with more fish breeds then you will need a tank of at least approx 100 litres for the breeds compatible with the paradise.
I'd be tempted to take your male paradise back and swap it for a female paradise as females live ok together. I wouldn't be adding anymore fish though apart from a catfish for the tank bottom as the tank is to small.
I wish my advice was happier but imo thats whats wrong at the mo
