The temperature is fine, – theres no need to do more about that.
Regarding feeding, in my understanding two times is far too much.
Paros are really fish that are very hardy when it comes to food. In their natural habitat food can be very little in periods, so they can survive (and does often in nature) with very low supply of food.
I feed mine once a day, – but many I think feed every second day. In some ways this could even be more healthy.
Unless of course there are fry in the tank, these needs more food.
Paros are not used to so much food, and it may be even unhealthy to over-feed with two times a day. Certainly is not their natural way of eating.
