Some others that I have found useful at one time or another include:
- great for getting concise info on many species
- very comprehensive site with plant profiles and other info
- great site for those getting into shellies from Lake Tanganyika
- another great site on aquarium plants
These are just a representative sample. I've bookmarked 28 web sites just dedicated to cichlids of various kinds and another 22 on planted tanks. I probably visit about a half dozen sites on a regular basis.
