I feed
1. Spectrum marine pellets
2. Kent Reef Herbivore Pellets
3. Spectrum RX pellets
4. Omega Kelp Pellets and flakes
5. Frozen Mysis shrimp and bloodworms soaked in Zoe, Zoecon, and Selcon and garlic extract.
6. Seaweed selects brown,red, and green
7. Spectrum optimum flakes (soaked in garlic right from manufacturer)
I've used tetra flakes before......not very impressed with them. I like pellets much better than flakes.
I keep six tangs all happy and fat. A couple have gotten really big in not much time at all.
