bullying discus

[friendlyfish]

hi got a few problems with my discus at the moment it bullied its friend to death and now looks around for it all the time the problem is I would like to get more but am now worried it will do the same to them. The other problem is they both have never eaten the discus pellets that I was told they had been eating the only thing it eats is aquarian tropical flakes and blood worm I know that these will keep him sustained but not so sure about there nutrional value can anyone shed some light thanks

Yes i think everyone who has owned cichlids have had the same thing happen in their tank. Id stop the bloodeorms and use Mals dried blackworms as they just dont fun the risk of going off through the transport / shop chain of handling. Do you have any idea of the sex of this fish? How many can the tank hold?
