I was reading through guidelines posted on the original site, and I saw a few things. An article said to use river rocks from Home Depot for the tanks and to never use sand. We all know that isn't the best option. Also, the feeding section didn't mention gel foods. I'm not being petty, but I thought maybe perhaps some updates to some of these articles might be a good idea. I didn't read through all the articles, so those were just a few things I noticed. I understand if the changes just aren't that big of a deal or its not important enough to change, I just thought I'd point that out!
