I had a Stealth 12 and you can put a good amount of bait in it. I had as much as 2 kayak scoops of anchovies in there which is too much (tipping the bait guy goes a long way). They started dying off so I just released some until they stop dying. One scoop is a pretty good start, the less bait in the tank the longer they last.

For sardines one kayak scoop did fine with only a few of the weaker ones dying off.

For macs it depends on the size. I'd be good with up to a half dozen usually, then make more later if needed. I never really tried to see how many I could stuff in there. With macks sometimes you get calm ones that kinda of just sit there allowing you to have a few more, or you get these crazy energizer macks that will beat up anything in their path, meaning you can't keep too many at a time.

Also, with bait (anchovies especially) I found it critical to turn down the water flow valve so they didn't get tired out and die. Better yet, make sure to use a 6v battery for the pump along with turning the flow valve down a lot. What they need is fresh water, what they don't need is a tsunami to swim against.

If your bait has bloodied red noses, you probably have too many stuffed in the tank.
