I was thinking of using a separate 10g aquarium for raising bloodworms. Is this a good food for cory cats/fathead minnows/black kuhli loaches/ghost shrimp? I figured corys would eat them because bloodworms naturally sink, and I figured the loaches would eat them because they are always on the bottom. But I'm not sure about any of these.

My plan is to put my current bloodworms (from a bucket in my yard) into the 10g and add about 2" of water. I'll add a piece of driftwood and feed them crushed triops food or zucchini/algae wafers. (Do bloodworms eat stuff like I plan to feed them?) Then I'll put a screen-cover over it, and just extract bloodworms from it to feed my fish.

Is this a good idea?
