I am a 'has been' enthusiast on malawi and tanganyikan cichlids. I have lots of great memories on keeping them and will doubtless return to keeping them in the future. Total 'fun' fish to keep.
If I had a favourite website on rift valley cichlids, it has to be this one:

Lots of activity, great suggestions, Richard who runs it is mad about malawis and keeps a great tone to the forum. Hope the new format works well over there.
