I have posted many times about great websites and online resources for cichlids. One that I think I may have forgotten about is Cichlid-Forum.com. This is a fantastic site and one that any cichlidophile should visit frequently and bookmark. In addition to a very active set of discussion forums, the site hosts volumes of information about cichlids including species profiles and product reviews.
If you haven't visited the site, please do. In fact, if you're a novice in the hobby and need advice or if you're highly experienced and want to give advice, consider becoming an active participant in the forums.
