I brought my new betta yesturday, and he was great in the LFS and my tank... But today he seems to be sad. All he does he stay still at the top of the tank. Yesturday he greeted me everytime I came to front of tank, but today he doesnt. He wont feed today even though he eat 2 flakes yesturday and still looks at me if he wanted more... Is this normal. Because Im starting to worrie.
