LOL Alberto I hear ya. Lots of folks use all sorts of different stuff in thier mixes. I believe Erik B has about everything bt the kitchen sink in his
.
I keep mine pretty simple (because i am lasy). Fish/corals/inverts and such have basically the same needs chemically (yes certain species of each can have special requirements if so then just add it to the mix) To give them this I use shrimp, scallops, salmon, nori and selcon. The contents of these basically provides all they need. The main thing you want to do is to make sure you have the right size particles, specially when it come to corals. So when making the blend make sure you get a good selection from fish size chunks to microscopic. For my tank I feed one ice cubes worth a day. For my tang I have to throw in about a quarter of a head of lettuce a day, but that is a different story.

You will find that enriched blend like this will be far superior to any live food you could use.
