I bought Ocean Nutrition Formula Two Frozen food for my cichlids and rainbows but i have not got any on them to eat it. It is hard to break up the gel cubes to fish size bites. It just clumps up and goes to the bottom. It has 2% garlic so i thought that might help temp the fish but they do not even respond to it as food. What is the problem? Anyone else not like this product? All fish are eating normal flake/pellet diet.
