I like to use the minnows under a bobber and to tip the jigs while spider rigging. SO with this in mind I acquired a large tank like the bait stores have and got it rigged with aquarium bubblers just like when i take them in the boat. So I go out and get two pounds of medium minnows and add them in the tank after getting the water adjusted for them. But I have been loosing quite a few as of lately and was wondering what you guys who buy minnows in bulk do to keep your alive for a long period of time.

Insight is the root to all is well. Any pictures of setups will also be welcomed.
