Pike Cichlid won't eat

[Maura]

We recently inherited a pike cichlid at the LPS where I work. I've tried what seems like everything and I just can't get him to eat.
I've tried:

• Beefheart (which is what the old owner fed him)
• Large feeder goldfish
• Small feeder goldfish
• Feeder guppies
• Tropical flakes
• Cichlid pellets
• Superworms
• Mealworms
• Waxworms

I need ideas...
Help please?

Check for bumps to see if it is sick if you find signs of disease then anti biotics you do not find signs of disease maybe bigger tank or pike cichlids love live guppies or wait a while then feed them.
