LOL that's so adorable. I'm in love with your fish. He seems to have such a good personality!
Finn like's to swim up and down the corners of the tank and swim against the small current my filter makes and than when he sees me looking at him, he just stares. And if he sees me hiding (i like to play hide and seek with him
), he'll come close to where I am to see where I went, and when I pop up he swims in his cave and pokes his head out lol.
