My Bettas go into tanks w/o filters. I have one 10g with a filter, but that's only because I got the filter free. It's a 20gal turtle filter. If I could get a bunch of really cheap 20g turtle filters, I would use them. They are silent and in the tank. I do not want HOB or other filters on/in/around these tanks.
BTW, heaters that need to hang on the side suck. Only reason is how high the water has to be and how they don't fit snug on. Other wise, they are awesome.
