The larger (older) of my 2 keyholes has been acting strangely this afternoon. At first I was panicking thinking that it was ill as it has been sitting on the bottom in the corner of my tank for the best part of the day. Tonight though, sitting and watching it seems to be that it is guarding the doorway to the coconut cave down in the far corner of the tank. Literally everytime another fish swims near it starts quivering and it's mouth opens up all wierd.
