Hello, I have a cycled 60 gallon tank that I recently stocked. I have a endlicheri bichir who is the star of the tank. He is currently about 4 inches. I also have 2 goby knights, 1 gold algae eater, 1 goldfish, and 2 koi angelfish. My LFS told me to feed the tank 2 cubes of frozen bloodworms every other day. Is that acceptable?
