Man I hate the, "can you eat them" line. Its like hurr hurr yeah lets go grill em up right now. Of course its to be expected from people who dont know any better. I would say sometime down the line we could exchange a few fire reds to keep the stock genetically diverse ....... but since we got them from the same souce and all. lol. Although if my CRS ever breed id be happy to sell you a few cheap.
Anyways that light looks good, reminds me of the marineland LED systems. I also not sure how I feel about that heater. I mean hydor is a good brand, at least from what I know about their inline heaters. But for a shrimp tank I dont think its needed, personally. But if it works for you then thats all that matters.
Also for the HC do you plan on getting co2? It will really NEED it to grow at all. It wont die without it, it just wont grow. A homemade yeast co2 setup will do just fine.
