SFBB Bloodworms Cube 1.75oz

San Francisco Bay Brand Frozen Bloodworms, 1.75 oz packs whole Chironomus plumosus midge larvae into 36 small mini-cubes made for desktop and nano aquariums. The tiny cubes let you feed a single betta, a school of small tetras, or a planted nano tank without thawing a full-size portion, so nothing goes to waste. Flash-frozen at their peak, bloodworms tempt even finicky eaters and bring out vivid color in freshwater fish. Browse more of our frozen and prepared fish foods.

Why the 1.75 oz Mini-Cube Pack

• Sized for small tanks. 36 mini-cubes are ideal for bettas, nano communities, and desktop aquariums where a full-size cube is too much.
• Irresistible to picky eaters. A high-value conditioning food that triggers a strong feeding response in shy 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.

How to Feed

1. Pop out one mini-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 pack to the freezer right away to keep the remaining cubes solid.

Frequently Asked Questions

How is the 1.75 oz pack different from the 3.5 oz box?
Both hold the same whole Chironomus plumosus bloodworms. The 1.75 oz pack uses 36 smaller mini-cubes made for nano and desktop tanks, while the 3.5 oz box has 30 full-size cubes for larger aquariums.

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.

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.
