I don't have a clown yet as I am waiting to get one from one of the members on here. Although they had resided in the same tank for the last month, my LTA ate my yellow clown gobie, before then, he had not gotten really close to it. However, the LTA had just moved behind the rocks to the side of the aquarium, one of the places my gobie used to travel to get to another 'hang out' spot in the tank. Darn it. Do they have a habbit of doing things like that?
