Why we recommend the San Francisco Bay Frozen Mysis Shrimp
When a fish refuses dry food, frozen mysis is one of the most dependable tricks in the hobby. These small whole shrimp deliver natural, protein-rich nutrition in a form fish instinctively recognize as prey, which is why even picky marine fish and newly imported specimens usually take them eagerly. San Francisco Bay packages them in pre-portioned cubes, so you can pop out exactly what you need without thawing a whole slab.
Mysis is more than a treat. It is a genuine conditioning food, widely used to fatten up thin fish, encourage breeding behavior, and support strong color and growth. A simple routine works best: thaw a cube in a little tank water, rinse it briefly through a net to remove excess pack juice, and then feed. That small step keeps dissolved waste out of the water and your parameters steady.
Who it’s for
This is a staple supplement for reef keepers, marine fish-only tanks, and freshwater hobbyists alike. It is especially valuable for anyone trying to get a stubborn new fish eating, or for breeders conditioning a pair before spawning. Because it is a rich protein food rather than a complete diet, rotate it with quality pellets, flakes, or dried algae so your fish get balanced nutrition across the week.
The Bottom Line
Frozen mysis is one of the most reliable ways to tempt difficult eaters and condition fish for breeding, and San Francisco Bay's cubes make it convenient. Thaw, rinse, and feed for a protein boost almost every fish loves.

Frequently Asked Questions
Do I have to thaw it first?
Yes. Thaw a cube in a little tank water and rinse it through a net before feeding to keep excess waste out of the tank.
Is mysis good for both fresh and saltwater?
Absolutely. It is a favorite across reef, marine, and freshwater tanks as a protein-rich treat and conditioner.
Can I refreeze leftover thawed food?
No. Thaw only what you need, since refreezing degrades quality and risks fouling. Feed promptly and discard excess.
Will it help my fish breed?
Mysis is a well-known conditioning food that supports the strong nutrition many fish need to come into breeding condition.
How often should I feed it?
A few times a week as a supplement works well. Keep it part of a varied diet rather than the only food.
