My Twinspot Hogfish is CONSTANTLY getting sucked into the overflow area... would help if I had eggcrate, but I think they are just small enough to get pulled through.


Edit: After posting this, I glanced at my tank to notice that he wasn't out swimming, so decided to check the overflow, and voila there he was, but he doesn't appear to be swimming properly, doing spins and laying down in the corner.... Wondering if he might have lost a side fin...
