How to make my bettas happy :)

In no particular order ;)
1. clean water! 2. lots of places to swim over, under, between, 3. places to rest, like big soft leaves, 4. warm water!, 5. yummmmy food like frozen or live food, 5. mix it up, when you do full water changes you could rearrange their decor or add new ones

I'm sure there's plenty more, those are just the few that popped into my head right away. ^^

Yeah, those are great tips! In repsonse to your question, it doesn't neccessarily make the water dirty, but the filter doesn't work as well and some of the bits it sucks up just go back in the water... so it's better to switch it sometimes! :) And wow, look at your avatar! Moonstone looks amazing, so healthy! :D
