quick question

i have a couple suckers left over from the other day fishin' that i put in my fish tank,
but i don't know what to feed them. anybody have any ideas??
the minnows love the tropical fish flakes but the suckers don't seem interested.
any help would be appreciated.

I found a couple of things...
    They are omnivorous, eating both plant and animal material along the bottom of streams and lakes.
 
This is from an article about a different species of sucker that they were trying to raise in a hatchery but might explain why they won't eat......
     Fresh, frozen, dried foods -nothing worked. But finally, last year they found the secret to getting the fish to eat. The water at the hatchery was too alkaline. A small change in pH, from about 8.8 down to 8.5 made a big difference. "They went on to feed immediately,"
 
Hope it helps....cheers

thanks for the help guys. i don't have my heater hooked up in the tank so they won't go into shock when i bring them back into the cold. they seem very happy in my tank (except for when my cat jumps on top of it) so hopefully they will be fine if they don't eat. i'll try the pleco wafers too.
 my receipt is valid thru sunday and the weather is looking good (35 degrees).
either hitting lake lonely or burden.
