Apparently, they need a temperature between 68-75F but from many other forums, I have heard of people keeping them in cold water too. I did forget they needed a tank of at least 24 inches for a group, my bad haha
Pygmy cories would be nice but they are pretty tough to get a hold of, or at least over here they are, would you believe no-one has even heard of them lol
Depending on your betta's personality you could keep ghost shrimp. I'm not sure how effective they are with cleaning as I've never kept them myself, however I did have RCS and my betta totally wiped them out
so I would recommend some hiding places and plants lol.
The main key to keeping the tank clean is regular water changes and gravel vacuuming but it is helpful when you have fish that give a little back too haha
