Sorry guys i have tried alot of different Brands Hikari is the best period the food is specie specific and as result works!!!!!In the end Good is not cheap and Cheap is not good!!!!That's just my Opinion...
I have the same size nls pellets and had the same problem. And the answer I found is that your pellets are too big for your bass. The pellets are too hard for the bass and nls is supposed to be swallowed whole not chewed unlike massivoure. I switched back to the 6mm pellets and they went right back to happily taking the pellets. My 16 inch kelberi is the only fish that will take the bigger pellets and eat them
its because there is no science behind NLS. its just a big turd pellet.
The NLS 10mm pellets are waaaaay to big & dense for a 6" cichla, no question about that. Seeing as you already have the food, I would take a hammer & break it up into smaller pieces, 3mm or so, and see how that goes. It worked for a friend of mine.
