Have I got a bully?

Just realized you are in England. So your tank is probably in UK gallons. So in US gallons its a 38g tank. Still... A bigger tank for them would help!

A larger tank would help a lot! Your tank is probably only 30-36" in length and 10-12" wide. Not a whole lot of space for this type of fish. A 55g would be a nice upgrade with a 48" length. But these guys really need some more swimming room.

The tank is 48" long, 12" wide and 15" deep. I have had to make sure they cannot run into any dacor when charging around.

The same fish is the one doing the bullying.
