Too much flow for 10 gallon?

I just bought a clown for my 10 gallon yesterday. At first, he swam around the whole tank but today when I was watching, he mostly just stayed in the corner next to my pump (assuming this part has the least amount of flow). When he does swim around it looks like he is struggling to fight the current. If I turn the pump off, he seems to use a little more of the tank but still mostly sits in a different corner. I know clowns can have weird personalities, but I'm wondering if he is stressed because of too much flow in the tank. Or do you think it's purely from being in a new tank? This is the pump I have: http://ift.tt/1pco4iO



Thanks for the help!
