Buddha ....... it has nothing to do with a difference of opinion, and everything to do with understanding the basic principles behind training a fish to eat - whatever you decide to feed it. If you can't train a "cichlid" to eat NLS I feel sorry for you. While I agree that with some fish it's not always easy, I've lost count as to how many fish I have personally trained, or seen trained, to eat whatever the owner decides that the fish will eat. (literally thousands of fish) Many of these fish were wild caught specimens, and had never seen a pellet in their life.
It's not rocket science, but there is some skill involved, and in some cases you need to have
great patience, and be smarter than the fish.
If an obligatory predator such as a V. lionfish can be trained to come to the surface of the tank, and eat floating NLS pellets, then training a cichlid should be mere child's play in comparison. Sometimes this can take days, sometimes weeks, and yes I clearly understand that in the mean time those chewed up (or ignored) pellets will make a mess. So clean up the mess, and carry on.
The reason that I showed those vids is they showed fish that are not always easy to convert to pellets, or wafers. The NLS wafers are also very hard, they stay firm for several hours once in the tank, yet not only can stingrays be trained to eat them, even the Asian aro in that one link grabbed one & chomped it down.
When I brought in my last flowerhorn from Bangkok it was a skinny malnourished fish that had never seen a pellet in its life, fed exclusively on bloodworms for its entire life. So i outsmarted the fish & soaked the NLS in bloodworm juice, and even still it took a solid 10 days or more before he readily accepted the pellets from my hand. Lots of leftover food & mess in the mean time, but that's what god created pythons for.
Now look at this beast in the making.

What, you don't think that at 50+ yrs of age I haven't tried other foods? I'm old enough to remember when dried ant eggs were considered a premium food.
FYI -
years before I had any vested interest in NLS I was promoting the product. Several yrs ago I was a mod on cichlid-forum in the Health, Nutrition, and Disease folder, and I promoted NLS just as much as I do now, perhaps even more back then. I don't work for New Life, I'm not a paid rep or marketing agent, and I don't sell to hobbyists who hang out on forums.
I also clearly stated to Ogrim
If you are happy with feeding Hikari then by all means carry on
I'm not holding a gun to anyones head, or insisting that anyone spend
days/weeks attempting to train their fish what they want it to eat.
I was simply offering many years of experience to my young mate in AU who has only been keeping cichlids for only 1 year. If he chooses to stick with Hikari for no other reason than it makes his fishkeeping easier, I have no problem with that.
