When conditioning fish for breeding, high quality foods are a must. Brine shrimp is an excellent conditioning food, as well as a perfect treat for any fish. Although fresh brine is ideal, frozen, freeze dried and flakes are an excellent source of nutrition for all your fish. Here are my top frozen brine shrimp choices.
1. San Francisco Bay Brand Brine Shrimp
San Francisco Bay has long been the top of the line in frozen brine shrimp. Available in cubes and flats of various sizes. Frozen foods don't always ship well during the summer months. Price what you want online then check your local pet shop to see if they carry it. 
2. Brine Shrimp Plus Frozen
Brine Shrimp Plus has seafood, plankton and Caulerpa algae added to the brine shrimp. You won't find a better all purpose enhanced brine shrimp product.
3. Tetra Delica Brine Shrimp
Suspended in a nutrient gel, is a unique method for offering brine shrimp. Initially the fish weren’t sure what they were, but once they found out they readily accepted them. This is a great alternative to live brine shrimp, which are often hard to find.
