I am currently feeding my 5" male dovii (180g single specimen, 2 Fluval 405's and Bio-Wheel 400 filters) Hikari Gold floating pellets once a day with a second feeding of earthworms (cut to size) or frozen Hikari krill on alternating days is this a good diet for health, color, growth etc.? Is anything missing or can be improved on? Also I have heard of people fasting their fish one day a week is this beneficial? Any imput/suggestions would be greatly appreciated. Thanks
