I use Hikari. For pellets I use Staple, Gold, Bio Gold Plus, Excel, and algae wafers.
For treats I use: Frozen and Freeze Dried Krill, Frozen Bloodworms, Frozen Market Shrimp, Live ghost shrimp, freeze dried river shrimp, Live nightcrawlers, live mealworms, and fry's.
Read the ingredients, The first ingredient is typically the number one ingredient and the most in the food. By far NLS wins hands down. There is some other upcoming foods that are getting close as good.
90% what we feed is it. We do supplement some HBH veggy flake & some soft pellets to some fishes. Also hikari frozen to Discus, other SA & salt water.
...no. Read the omega one ingredients, its basically the same thing. Instead of "fish meal" like in most brands, they say "*specific seafood species* meal"
I'm pretty sure that listing all the specific types of fish that go into it is mostly marketing.
