SFBB Mini-Bloodworms Cube 1.75oz

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. This 1.75 oz box holds 36 individually portioned mini-cubes, an ideal size for desktop and nano aquariums, so bettas, tetras, and rasboras get a clean, no-mess feeding without a lot of leftover food.

Pair it with other frozen favorites like SFBB Cichlid Delight and SFBB Beefheart, or browse all of our frozen and prepared foods. Feeding a bigger tank? The same food comes in a larger 3.5 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.
• Made for small tanks. The 36 mini-cube pack is sized for desktop and nano aquariums, nano fish, juveniles, bettas, and community species that struggle with full-size bloodworms.
• Clean, portioned cubes. Individually frozen mini-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 mini-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 and nano tanks?
Yes. Bloodworms are one of a betta's favorite foods, and the 36 mini-cube pack is sized for small desktop and nano aquariums. 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.
