Some of my picky eaters that don't like Spectrum pellets, are going after PE pellets.
Even my nassarius snails are coming out looking for food, they only do that when I feed frozen food. Pretty impressive
Only down side is the 1mm is really small. I've always fed my fish Spectrum 1mm, and this seems to be quite a bit smaller. I already ordered the 2mm, which should be perfect. I'll probably end up mixing the two, that way my smaller fish can eat the 1mm and the larger tangs can eat the 2mm.
Anyways, it's good stuff, give it a try!
