SFBB Bloodworms Cube 3.5oz

San Francisco Bay Brand Frozen Bloodworms are whole Chironomus plumosus midge larvae, flash-frozen at their peak to lock in the natural color and nutrition freshwater fish crave. A long-standing favorite treat, bloodworms tempt even finicky eaters and bring out vivid coloration in community fish, bettas, discus, cichlids, loaches, and gouramis. Each 3.5 oz box holds 30 pre-portioned cubes for clean, mess-free feeding. Browse more of our frozen and prepared fish foods.

Why Frozen Bloodworms

• Irresistible to picky eaters. A high-value conditioning food that triggers a strong feeding response in shy, stressed, or newly added fish.
• Rich in protein and iron. Supports growth, energy, and the deep coloration hobbyists love in bettas, tetras, and cichlids.
• Cleaner than live. Flash-freezing reduces the parasites and bacteria that live bloodworms can carry, so you get the appeal of live food with less risk.
• Pre-portioned cubes. Thirty individual cubes per box let you feed exactly what your tank needs with no thawing waste.

How to Feed

1. Pop out one cube and thaw it in a small cup of tank water. Never microwave or refreeze.
2. Feed as a treat 2 to 3 times per week alongside a staple flake or pellet.
3. Offer only what your fish finish in a couple of minutes, then net out anything uneaten.
4. Return the box to the freezer right away to keep the remaining cubes solid.

Frequently Asked Questions

Which fish eat frozen bloodworms?
Almost all freshwater community fish relish them, including bettas, tetras, barbs, danios, rasboras, gouramis, loaches, discus, and cichlids. They are especially useful for conditioning fish before breeding.

Do I have to thaw the cubes first?
Thawing one cube in a cup of tank water is best. It keeps feeding clean and lets you pour off excess liquid before adding the worms to the tank.

How often should I feed bloodworms?
Feed them as a treat 2 to 3 times a week, not as the only food. Bloodworms are high in protein but work best alongside a balanced staple diet.

How do I get it home still frozen?
We keep it in our freezer until you pick up, and we recommend an insulated bag such as the SFBB Fish Food Icebox for the trip home. Do not refreeze once it has thawed.
