Planted Nano Tank
I am setting up a planted Nano 10G tank with the intent of housing a Crowntail Betta in there eventually. I have all the equipment I need so far but I am stumped on which filter to get. I would want a filter that does a good job on a 10G (20 x 10 x 12) but that doesn't agitate the water overly so that the Betta doesn't get mad at me in the long run. The tank being small as it is I would like something along the lines of an HOB power filter (so it doesn't take up too much room in the tank) but I'm afraid that the water intake tube may be too dangerous for the Betta's fins to get stuck into (not counting the water return flow which may infuriate the poor fish as it swims along).
Does anyone have any suggestions? Are there any good alternatives out there?
