i put my stevenis in 3 feet tank.. when i went back from KL in two weeks time, i found out 5 of them were death.. so i change them into my 4 feet tank with my red empress.. when i went back yesterday (after two weeks time), i found out that all of my steveni were death but one.. the last one is having abdomen problem.. she's eating but her her abdomen is so-so thin.. like never eating anything.. so, how to solve her problem??.. and what happened to the others??.. what kind of disease is this??.. please note that, all other red empress was ok (all juvenile).. n they're not fighting..

i dont really know what happened ar.. really stress me out..

sorry Eziegy, all your Stevenis were gone..
