SFBB Mini-Bloodworms Cube 3.5oz

SFBB Frozen Mini-Bloodworms are bite-sized cubes of whole bloodworms (Chironomus plumosus), a rich, high-protein treat that almost every freshwater fish attacks on sight. The smaller "mini" cut is portioned for community and nano fish, juveniles, and any species with a smaller mouth, so bettas, tetras, and rasboras can take it without a struggle. Each box holds 30 pre-measured cubes, so you thaw only what you need with zero mess.

Pair it with other frozen favorites like SFBB Cichlid Delight and SFBB Beefheart, or browse all of our frozen and prepared foods. Want a smaller pack? This same food also comes in a 1.75 oz size.

Why frozen bloodworms

• Irresistible to picky eaters. The natural red color and scent trigger a strong feeding response, perfect for tempting new, shy, or finicky fish.
• High protein for conditioning. Bloodworms are packed with protein and iron, which makes them a favorite for conditioning adult fish before breeding and for putting weight on thin or recovering fish.
• Mini size for small mouths. The smaller cut suits nano fish, juveniles, bettas, and community species that struggle with full-size bloodworms.
• Clean, portioned cubes. Individually frozen cubes mean no scooping, no waste, and easy control over how much you feed.
• Safely processed. San Francisco Bay Brand freezes its worms to help reduce the parasites and bacteria that can come with live food.

How to feed

Pop one cube into a small cup of tank water and let it thaw for a minute or two, then pour it into the aquarium or target-feed it with a pipette. Offer bloodworms as a treat 2 to 3 times a week alongside a quality staple food, not as the only diet. Feed only what your fish finish in a couple of minutes and net out anything left over. Do not microwave the cube and do not refreeze a thawed one.

FAQ

Are these good for bettas?
Yes. Bloodworms are one of a betta's favorite foods, and the mini cubes are an easy size for them. Offer them as a treat a couple of times a week rather than every day.

Can I feed bloodworms as a complete diet?
No. Bloodworms are a rich supplement, not a balanced staple. Feed them alongside a good flake or pellet so your fish get complete nutrition.

What is the difference between the mini and regular bloodworms?
Only the worm size. Mini bloodworms are the smaller-cut larvae, which suits nano fish, juveniles, and smaller-mouthed community fish. Larger fish can eat either size.

How long does a box last?
Kept solidly frozen, the cubes stay good for months. Just avoid thaw-and-refreeze cycles, which break down the food and can foul your tank water.
