I have a lovely little weird catfish, Crysichthys Ornatus aka Chris who only ever comes out properly at 7am every morning and he comes to the front glass and does continuous loop the loops without stopping for half an hour (i dont bother trying to stop him any more, he just gets up set!) and then he gets his prawns for breakfast and then he goes back to bed in his upright 'chimney' (was a biorb decoration!)
