None of my fish like this.

These are little sponge like squares. The feeding instructions say to open container and tap desired amount into tank. I broke one up as best as I could. None

My Fish Won't Eat It

My fish would not eat this product. They'll nibble it and spit back out. I used it with my guppies, tetras, angel fish, danios, and pet bluegill in separate tank

My turtles like these cubes, after I break them up.

These cubes must be tasty to my turtles. I break them up so they don't choke on them.

I love that these are parasite and disease free!

So many other worms carry destructive worm eggs to a healthy tank. I can feed these to my fish without concern.

The amount of worms in the container.

With the small amount of worms I received it was not a good value.
