Although I realise this is a different species, I suspect you risk losing your pike if you try and house it with anything too large! There are many instances of this kind of thing happening if you google it.
Yeah i have about a 19 inch LMB in a pond and chubs are his main diet, they are really easy to catch in the small creeks of my neiborhood. the biggest weve ever caught was about 10 inches.Had a 10" creek chub swallowed a 7" northern pike fingerling.
Some predators are so greedy they cant be housed with anything! European perch are another example...
