Everyone has been great so far. It's been over 30 years since I had an aquarium so any old habits I had are long forgotten. A blessing of old age (or curse depending on what you have forgotten) Back then I bought a tank, threw a bunch of fish in and by some miracle all seemed to go well. I had that tank for a long time, but when I got married and moved the tank stayed behind. I keep thinking of lots of questions, such as is sand or gravel the best substrate, I was going to put some tetras in the tank, cause I read somewhere that was good for the Discus, is that true?, what kind of bottom fish work best with Discus if I decide to put a couple in? Is the 3D backing I see advertised any good in a discus tank? Can I collect driftwood along the river and use that in my tank, and how should I clean it first. I have been doing a lot of reading on-line but it all kind of runs together after a while because there are so many different opinions. I joined Simply Discus because a bunch of people cared enough about their fish to get organized and help each other and that sounded right to me. Thanks again everyone, I may be a bit of a pest for awhile.
