Dylan, it is hit or miss what they will host, or "bond" For example I have one in my 29G, and he loved my hammer coral. For whatever reason I moved the hammer coral to another tank. He was fine without anything, but now hangs around with the Frogspawn. I just recently got two Sebae Clownfish (last weekend actually) for my 38G, and they hang around the hammer coral during the day, and bed in my Xenia at night. I guess long story short, it really depends on the fish, and you'll just have to wait and see.
