My 3"-4" juvies love this stuff, but a couple of things to note if you are just starting out feeding pellets...1) fish that have been fed flake and freeze-dried foods will "taste" these pellets as they fall but generally spit them out or ignore them altogether for a while, so start off with just a very small amount, let the pellets sink, and the discus, in their normal habit of searching around for food after the main feeding, will eventually find the pellets on the bottom and begin eating them.  It's harder to control in a planted tank, so remember to turn down your filters if adjustable, then hold the pellets underwater with your fingertips while releasing a few at a time.  That way you can control to some degree where they fall...I have left a couple of bare areas on the substrate so that the majority of sinking pellets fall there rather than into my plants, although after your fish get hooked...pun intended...on these they will hunt them down even in the densest vegetation. 2) the pellets are relatively hard so even after the discus begin eating them, some of your pickier fish will continue to take them in then spit them out until they soften enough to be crushed and eaten. 3) do be careful not to over-feed.  I had to recently "hospitalize" one of my larger piggies (you know the type...thinks ALL the food is just for him), who gorged himself to the point of bloating and had to have a 24 hour regimen of Epsom salt in the hospital tank to correct his gluttony...poor sucker was swimming upside down for half a day until he got his swim bladder re-regulated and the laxative did it's job overnight.

Anyway, this is great stuff...my 12 discus really go for it, and along with Discus Hans flake food and freeze-dried Hikari blood worms, constitute the entire diet for my fish, which are growing like weeds and are now taking food directly from my fingertips after about a month on the pellets.
