so all of the sudden my hippo tang has been taking my small clam (~2 1/2-3 in) for a joy ride then dropping it around my tank. he doesn't seem to be picking at it. not sure why he started doing this. I seems like he just doesn't like it around anymore. I've had it in the tank for about a month and it's been doing fine. Now i've got this problem. Anybody have any ideas why or has anybody had this happen to them. I really don't wanna lose the clam nor do i wanna get rid of my hippo tang. had him for 3 years. Thanks for any input!
