We bought Rod's Reef (Brian and I share the package). It's a frozen food. It sounds similiar to what a lot of you mix up in your blender - I just can't bring myself to do that (UGH). We only feed it to our tanks occasionally. I use it in my 24 Nano about every 2 weeks. My tank goes crazy. I do break up the chunks when I defrost it but the clown fish make short work of it. Of course I'm feeding a small amount so the expense wasn't a huge issue. I bought it for variety and my lfs recommended it - they use it in their reef tanks weekly. It has squid, brine shrimp, octopus, mysis, etc. I can't say that it's the food (credit should probably go to Ziggy) but my corals are doing great. Pics soon. Got the new camera I've been asking for today. Now I just need to figure out how to get some good pics and post them.
