Nls is great. I have found great success with omega-1 super colour cichlid pellets. It is a fair bit less money than nls, at least where I am located. I was using xtreme aquatic foods and it clouded up my water pretty much by the 3rd day of using it. The fish seem to really hit the o-1 for me though. Good ingredients. Just starting to use hiKari carnivore and it’s mixed opinions amongst my fish some love it and others spit it out and watch it hit the ground.
