I've been reading about the healthy and entertainment benefits that Live Brine Shrimp bring to fish. I was wondering what is the best way to bring this to my fish. Is it easier to purchase live brine shrimp from the lfs or to DIY with a hatchery? I have a mini bug aquarium and an air pump that might be useful as a hatchery.. what makes the most sense? Its more of a treat than a constant food supply if that changes anything...
