so i have recently dropped my 55 gal stock to just 2 jack dempsey's, and from what i have read, one is male and one female. i have just started to feed krill, its wardey's brand. well they love it and im now feeding it more than other food i normal feed them. is there any advantages to krill, i have heard it brings out more colors, if thats true how long intill i will see any results.
