I wanna try the Dainichi cuz its got more color enhancers than any other food out there that i know of, and they are all natural. Plus they are the only pellet food that incoperates Cyclopeze...which is a proven Red color enhancer....AND they have that clay stuff encapsulated around it to help with digestion...it just seems like a whole new level of fish food and I wanna give it a go. I already use NLS, so i was thinkin of gettin some new fish...same species...and splittin a tank into three with dividers. Same # and type of fish, same water, same everything, only difference would be the food. One group would get regular food(they will be the control group), one will be fed the Dainichi pellets, the other the NLS. Should give me results...what'cha think?
