Excellent quality food. I feed this to my fish about 4x a week as a treat. They eat it fast.

    • Saved our fish that refused to eat! Great purchase!
Size: 0.28 Ounce (Pack of 1)
I am not sure how to rate flavor, I am not about to taste a blood worm. However, based on the fish’s response to the food, it gets 5 stars! Overall, Tetra Blood Worms Freeze Dried Treat saved our Betta. I would recommend this to anyone with a Betta. But more specifically, one that has no idea what they are doing with a fish and are at that point where their child has bugged them enough for a fish, that you finally cave. We received our fish mid-April as a birthday gift for my son and had Betta food that was recommended at the pet store. It did not seem like the fish was eating the food. After a few weeks the fish started looking rough. It was losing its gorgeous color and its fins seemed to be deteriorating. We thought, for sure, the fish was not going to make it and started prepping for how to handle this with our young son. As a last ditch effort, I started searching the web for what may be wrong with our Betta and found many open ended answers. The fish seemed to take in the food we had and spit it out. One site said they were eating and taking small bites, another said maybe it was too big? One site someone commented how their Betta loves Blood Worms and gets excited when they see it coming. I laughed about it, and thought, we will give it a shot. Then I can at least tell my son we tried. So, the food came just in the nick of time. It was on the bottom of the tank, blackish looking...the beautiful blue and orangey red it originally was, gone. The fish was on its last leg/fin. I put a little food in and watched intently for about 10 minutes. Finally, the Betta went up and nibbled. A piece went in his mouth, then out. This happened a few times, and I figured same thing. Failure. But then, another bite, and it stayed in! I watched it continue to nibble. I fed it again that night. The next morning, it’s color already started coming back and it was more active. Today is day 4 on the food. The fish is back in action! Color is coming back beautifully and super active. Dare I say, it even gets excited when it sees me coming with the food?! Tetra Blood Worms Freeze Dried Treat Is a must for anyone with a Betta! ... show more

This fish food has worked really well in my aquarium. My fish took to it quickly and seem active and healthy when eating it. It’s easy to feed, and a small amount goes a long way, which makes it convenient for daily use. It doesn’t cloud the water much and helps keep the tank cleaner compared to other foods I’ve used before. The fish stay interested at feeding time, and I’ve noticed steady growth and good color over time. Overall, it’s a reliable fish food that’s easy to use, keeps fish happy, and helps maintain a clean, healthy tank. ... show more

    • Great Product
Size: 0.25 Ounce (Pack of 1)
I have this product as a subscription. It is fabulous for my tetra fish community. I only feed these to them 3 times a week. I will admit, frozen bloodworms are better. I add these with my bug bite food and my fish go crazy. I don't like frozen foods for my larger aquarium because that falls down into the water column and hits the bottom. With these, they float on the top of the water and I can remove them if my fish don't eat them all. Helps me keep the tank a bit cleaner. I do want to mention that not all of the bloodworms are consistent in size. This works well for my tank because the bigger fish will eat the larger pieces. The powder and smaller pieces are excellent for my baby fish in the breeder tank. Really nothing goes to waste for me. I also have a Venus flytrap plant that I feed these to. Overall, I am happy with this product and will continue with my subscription service! ... show more

    • No need for a “Beta” test. These are great.
Size: 0.25 Ounce (Pack of 1)
My daughter uses these for her Betas and I have used them for a newborn hatchling turtle. There is like a million little blood worms in this bottle. They are super tiny, so they work great for feeding your fish. No bad smells or fouling up your water either. Just be sure to not over feed your fish unless you have some kind of bottom feeder that will take care of all the tiny bloodworms that sink down and settle in the rocks. For anybody that has never used these before, they are dried, so it’s not like you are dealing with some type of moist slimy food. I think your fish will really dig these. So atleast give them a shot. The price is a pretty good deal, so it’s not like you are gonna have to break the bank whenever you need to buy more. Plus you could just use these as a secondary food source so you pet can be getting a balanced diet. It’s always best to have a few different foods on hand so you can mix it up a bit, and this is one to definitely have in your selection. I, with no hesitation will suggest this for your fish. You’ll see just how fast they dart at these when you try them out for yourself. ... show more
