My fish love this

On a whim I tried these. As soon as I dropped 1 to try my large Pleco came out of hiding and went straight for the food. This was the fastest and strongest reaction he's ever given me to food. After months using this fish food he's still quick to come eat. He's never left any food behind. I can drop 4 to 5 at a time and it doesn't cloud the water, it doesn't turn into a blobby mess and float around the tank. Really happy about these tablets!

Expanding blob of egg drop soup

Expands. Sinks. turns into blob of stuff that resembles egg drop soup and none of my fish or bottom feeders will touch it. Caused ridiculous mess in my 5gal tank. Maybe if you had larger fish in a much larger tank then it would make sense but too much of a mess for me;

Big fan of Cobalt

Love their products and so do the aquatic pets. This will do nicely for my invertebrates and bristlenose plecos.
