Freeze-Dried Blackworms: 100% Real Blackworms, Nothing Added
Our All Natural freeze-dried blackworms are exactly what the bag says: real freshwater blackworms (Lumbriculus variegatus, often called California blackworms) with nothing added. They are farmed by Aquarem in bio-secure aquaculture facilities, raised in spring water on specialized feeds, then frozen and freeze-dried with no preservatives. The result is a 66% protein, shelf-stable fish food that gets the feeding response of live worms without keeping worms in the fridge.
This is the original formula in our blackworm line and the simplest place to start, from 5g trial bags up to 500g for fish rooms and breeders.
Why Fish Go After Blackworms
- Strong feeding response: picky eaters like Discus and Betta that ignore pellets will often eat blackworms.
- Conditioning food: a long-time favorite of breeders for bringing fish into condition.
- High protein: 66% protein to support growth and color.
- Freshwater and marine: suits Discus, Betta, Cichlids, Guppies, Tetras and other tropical fish.
How to Feed Freeze-Dried Blackworms
No rehydration needed. Press a cube onto the aquarium glass and let fish pick at it, or drop it on the surface for surface feeders. For mid-water and bottom feeders, soak a piece in a little tank water until it softens and sinks. Crumble it for small fish. Feed 1 to 2 cubes daily alongside a staple diet, and remove anything uneaten after a few minutes.

Freeze-Dried Blackworm FAQ
Are these real blackworms or tubifex?
Real blackworms, Lumbriculus variegatus, not tubifex worms (Tubifex tubifex) sold under another name. Read why it matters in Not All Blackworms Are Really Blackworms.
Do I need to soak freeze-dried blackworms?
No. Dry cubes stick to the glass or float for surface feeders. Soak a piece in tank water for a minute or two if you want it to sink for bottom feeders.
How much should I feed?
1 to 2 cubes daily, as part of a varied diet with a staple pellet. Blackworms are rich, so start small and feed what your fish finish in a couple of minutes.
Are blackworms better than bloodworms?
Freeze-dried blackworms are 66% protein, higher than most bloodworm products. Many keepers feed both for variety. We compare them in Freeze-Dried Blackworms vs Bloodworms vs Live.
Are freeze-dried blackworms good for axolotls?
Yes. Our Axolotl Munchie Cubes are freeze-dried blackworm cubes sized as a hand-feeding treat.

I started keeping discus around 8 months ago about 12 years into this hobby. Learned pretty fast that discus can be picky eaters, and with having to feed them 3 to 4 times a day for growth... not a great combination.
I saw super cichlids on Amazon and decided to take a chance on them. It's been the best decision I made. Been feeding my discus the freeze dried color enhancement black worms for over a month now.... and boom! The fish are big, healthier, and more colorful than ever in the past 8 months. They are thriving! I whole heartedly feel it because of adding these freeze dried black worms to their diet... not a single worm is wasted.
Been feeding this as one of the foods I feed my discus juveniles and they go crazy for them. Love that it sticks to the glass so that I can visually inspect my fish.
My picky Discus loved these even over blood worms. I am contemplating dropping frozen food and going with these as a replacement.
I fed my fish a variety of blood worms and tubliflex worms. Decided to give black worms a try because of the higher protein levels. My fish LOVE this stuff. More then even blood worms which I’ve stopped feeding them now that the black worms have become a favorite
Great product and they even send a thank you note with candy !!
Nice personal touch!!
Well-priced quality product, I have been feeding this product to my cichlids for years now, with no issues at all. Excellent presentation and packaging.
My Cory’s can’t wait for these to go on the side of the tank. They eat this right out of my hand as soon as it hits the water they are all about the cubes.
Awesome, my froggies love it
All my fish and inverts go crazy for the freeze dried black worms. These are a great substitute for feeding live foods. Highly recommend buying from Super Cichlids. Great customer service, excellent packaging and expedient shipping.
Great food. Finally got my axolotl to eat after weeks of not eating.
Great product. It finally got my axolotl to eat after weeks of refusing to eat.
Our Haps and Peacocks consistently thrive on Super Cichlid cubes, a testament to their quality. We appreciate Lisa's exceptional service, particularly her personalized thank-you notes and the inclusion of samples and Swedish Fish with each order. We commend Super Cichlids for their continued excellence.
I love this as a treat on Fridays all my fish go crazy for it.
Great food for my Discus Fish.
My big South American cichlids LOVE this!
Fish love them!!!
The fish have never seen Premium Freeze Dried Blackworms before, but they devour them. Their color seems brighter and they seem more active. Included as a sample in a previous order, I was overwhelmed how much they loved them, so I ordered some. I feed as a treat every 3 days. A++ for Super Cichlids.
My fish really love them. They’re eaten as fast as I can get them in the tank
Great quality freeze dried black worms. The discus and angel fish devour it as soon as I put it in the tank. I get the power boost to add variety. Great product.
My discus literally tear these out of my hands before I can stick them on the glass, and the personal touch customer service gives with each order is above and beyond, great quality food. I will be back.
fish is slow to eat this food, but they are getting there .thank you
My discus have been happy healthy and parasite free the entire time using these freeze dried black worms. They’re addicted! Fast and friendly shipping and service
I ordered my first bag in the 15 g weight off Amazon and my fish loved them! I am now running a fish room with 13 tanks with hundreds of fish growing out and at different stages of life. I just ordered the 25 g and received it with spirulina power boost this time and to all the tanks large enough to receive these cubes as part of their diet... Well I'll attach some pictures so you guys can see for yourself. The colors and energy levels of my fish are just spectacular. Highly recommend this product and I will certainl
My fish love them. The came sooner than expected. Thanks super cichlids.
From start to cart to shipment and finally feed, this is the best on the market. All my fellas love them, they go crazy for them. Get you some!
Products was ok, price a little high
Fish really like this!!! I put multiple squares out because my larger fish take it right off the glass.
SUPER CICHLIDS IS A TOP NOTCH COMPANY.
Discus & Rams definitely loved this product
Discus love it, definitely should've purchased more.
As the seller suggests, you can just push a cube of these worms against the aquarium glass and your discus will go absolutely crazy about it. Even the most finicky eaters will come out to get some! Thank you - thank you! I and my discus guys love these!
