BGK fish seem to die very easily slight changed in water ther normally the first to go its a shame really i have had a problem with them before

Dont belive this! Just added the knife fish and it looks like its dieing, could it just be stressed?
All the other fish seem fine and have no thing visually wrong with them. The knife fish can swim fine but keeps lieing on the botton like it has no sence of direction or its disorientated. Cheers, Joemuz
